  1. Q1. What is the overall stopping distance at 30 mph on a dry road?

    1. A. 12 metres (40 feet)
    2. B. 23 metres (75 feet) Correct answer
    3. C. 36 metres (118 feet)
    4. D. 53 metres (175 feet)

    Explanation. At 30 mph: thinking distance 9 m + braking distance 14 m = 23 m (75 feet) overall.

  2. Q2. What is the overall stopping distance at 70 mph on a dry road?

    1. A. 53 metres (175 feet)
    2. B. 73 metres (240 feet)
    3. C. 96 metres (315 feet) Correct answer
    4. D. 120 metres (396 feet)

    Explanation. At 70 mph: thinking distance 21 m + braking distance 75 m = 96 m (315 feet). The Highway Code quotes 96 m.

  3. Q3. In wet weather, how much longer can stopping distances be?

    1. A. The same
    2. B. Twice as long Correct answer
    3. C. Three times as long
    4. D. Four times as long

    Explanation. Wet roads significantly reduce tyre grip. Braking distances can be at least twice as long — double your following distance in the wet.

  4. Q4. On icy roads, stopping distances can be up to how many times greater than on a dry road?

    1. A. Twice
    2. B. Five times
    3. C. Ten times Correct answer
    4. D. Fifteen times

    Explanation. On ice stopping distances can be up to ten times greater. Drive at very low speeds and leave a massive following gap.

  5. Q5. What is the two-second rule?

    1. A. Allow at least two seconds to pass a junction
    2. B. In dry conditions, stay at least two seconds behind the vehicle in front Correct answer
    3. C. Check mirrors every two seconds
    4. D. Use two-second intervals when changing lanes

    Explanation. The two-second rule ensures a minimum safe following distance in dry conditions. Double it in the wet and multiply by ten on ice.

  6. Q6. What is "thinking distance"?

    1. A. How long the brakes take to slow the car
    2. B. The distance travelled while the driver perceives a hazard and decides to brake Correct answer
    3. C. The gap between two vehicles
    4. D. The time to check mirrors

    Explanation. Thinking distance is the distance your vehicle travels between you seeing a hazard and your foot actually pressing the brake. At 30 mph it is 9 metres.

  7. Q7. What is "braking distance"?

    1. A. The distance from the car to the vehicle ahead
    2. B. The distance the car travels once the brakes are applied until it stops Correct answer
    3. C. The total stopping distance
    4. D. The distance travelled while thinking

    Explanation. Braking distance is the distance the vehicle actually travels while decelerating from the moment the brakes are pressed to a complete stop.

  8. Q8. Which factor does NOT affect braking distance?

    1. A. Tyre condition
    2. B. Road surface condition
    3. C. The colour of the vehicle Correct answer
    4. D. Vehicle speed

    Explanation. Braking distance is affected by speed, tyre condition, road surface, weather conditions and the vehicle's braking system. The colour of the vehicle has no effect.

  9. Q9. You are following a large vehicle on a motorway. Why should you leave a large gap?

    1. A. Large vehicles are heavier and take longer to stop; a large gap also improves your view of the road ahead Correct answer
    2. B. Because large vehicles use air brakes which take time to activate
    3. C. There is no special reason — treat it like any other vehicle
    4. D. To give you more time to change lanes

    Explanation. Large vehicles have greater stopping distances and restrict your forward view. A larger gap gives you a much better view of what is ahead and more time to react.

  10. Q10. What should you do if you are being tailgated?

    1. A. Brake sharply to warn the driver behind
    2. B. Gradually increase the gap between you and the vehicle ahead, giving yourself more stopping room Correct answer
    3. C. Speed up to create space behind you
    4. D. Flash your brake lights

    Explanation. If you are tailgated, creating extra space in front of you gives you more time to brake gradually. Sudden braking can cause a rear-end collision.

  11. Q11. At what speed does your overall stopping distance double compared to 30 mph?

    1. A. 40 mph
    2. B. 50 mph Correct answer
    3. C. 60 mph
    4. D. 70 mph

    Explanation. At 30 mph stopping distance is 23 m; at 50 mph it is 53 m — more than double, due to the non-linear relationship between speed and braking distance.

  12. Q12. Why do cars take longer to stop on roads that have been freshly surfaced with loose chippings?

    1. A. The chippings damage the tyres
    2. B. There is less grip between the tyres and the surface Correct answer
    3. C. Cars are not designed for such roads
    4. D. There is more grip

    Explanation. Loose chippings reduce tyre-road contact and therefore grip, increasing braking distances. Slow down and increase following distances on freshly surfaced roads.

  13. Q13. You are driving on a foggy night using fog lights. When can you turn the rear fog light off?

    1. A. As soon as you leave the foggy area
    2. B. When visibility improves to more than 100 metres Correct answer
    3. C. Only when you reach your destination
    4. D. Fog lights should remain on until you have parked

    Explanation. Rear fog lights must be switched off when visibility improves above 100 metres — they dazzle drivers behind and can obscure brake lights.

  14. Q14. What affects how quickly a driver can react to a hazard?

    1. A. Speed only
    2. B. Tiredness, alcohol, drugs, distractions and health all increase reaction time Correct answer
    3. C. Only age
    4. D. Nothing — reaction time is constant for each driver

    Explanation. Reaction time (and therefore thinking distance) is increased by tiredness, alcohol and drugs, distractions, illness, and age. Anything that slows your mental processing extends thinking distance.

  15. Q15. You are driving at 60 mph and the vehicle ahead brakes suddenly. What is the likely stopping distance needed?

    1. A. About 23 metres
    2. B. About 53 metres
    3. C. About 73 metres Correct answer
    4. D. About 96 metres

    Explanation. At 60 mph the overall stopping distance is approximately 73 metres (240 feet). You must always keep enough clear distance to stop within the distance you can see to be clear.

  16. Q16. In dry conditions at 30 mph, roughly what overall stopping distance should you allow?

    1. A. 9 metres
    2. B. 14 metres
    3. C. 23 metres Correct answer
    4. D. 36 metres

    Explanation. At 30 mph the typical overall stopping distance in good, dry conditions is about 23 metres (6m thinking + 14m braking).

  17. Q17. A typical overall stopping distance at 20 mph in dry conditions is about:

    1. A. 6 metres
    2. B. 12 metres Correct answer
    3. C. 20 metres
    4. D. 30 metres

    Explanation. At 20 mph you need around 12 metres overall (6m thinking + 6m braking) in dry conditions.

  18. Q18. What is the approximate dry stopping distance at 40 mph?

    1. A. 23 metres
    2. B. 36 metres Correct answer

    1. A. 73 metres
    2. B. 84 metres
    3. C. 96 metres Correct answer
    4. D. 120 metres

    Explanation. At 70 mph the overall stopping distance is roughly 96 metres, about the length of a football pitch.

  22. Q22. On a wet road, stopping distances should be treated as roughly:

    1. A. The same as dry
    2. B. Twice the dry distance Correct answer
    3. C. Three times the dry distance
    4. D. Ten times the dry distance

    Explanation. Wet roads typically double the overall stopping distance compared to dry.

  23. Q23. In snow or ice, stopping distances can increase by as much as:

    1. A. Twice as long
    2. B. Four times
    3. C. Seven times

    Explanation. On icy surfaces distances can be up to ten times greater than on dry roads.

  24. Q24. Thinking distance is best described as:

    1. A. The distance the car travels after the brakes bite
    2. B. The distance travelled while you react to a hazard Correct answer
    3. C. The total stopping distance
    4. D. The distance to the car in front

    Explanation. Thinking distance is the distance covered during the driver's reaction time before braking begins.

  25. Q25. Which factor most obviously increases thinking distance?

    1. A. Worn brake pads
    2. B. Tyre pressure
    3. C. Tiredness or distraction Correct answer
    4. D. Road surface

    Explanation. Fatigue, distraction, alcohol or drugs all slow reactions and extend thinking distance.

  26. Q26. The two-second rule applies in:

    1. A. Heavy rain
    2. B. Icy conditions
    3. C. Good dry conditions Correct answer
    4. D. Thick fog

    Explanation. The two-second rule is only a guide for dry weather; poorer conditions need longer gaps.

  27. Q27. In wet weather you should follow the vehicle in front using at least:

    1. A. A one-second gap
    2. B. A two-second gap
    3. C. A four-second gap Correct answer
    4. D. A ten-second gap

    Explanation. Double the two-second rule to four seconds when the road is wet.

  28. Q28. How can you measure a two-second gap?

    1. A. Look at the speedometer
    2. B. Pick a fixed point and count after the vehicle ahead passes it Correct answer
    3. C. Count car lengths
    4. D. Watch the brake lights

    Explanation. Choose a fixed roadside point; when the car in front passes it, say "only a fool breaks the two-second rule" before you reach it.

  29. Q29. Aquaplaning happens when:

    1. A. Brakes overheat
    2. B. A layer of water lifts the tyres off the road Correct answer
    3. C. Tyres lose air pressure
    4. D. The clutch slips

    Explanation. Water builds up in front of the tyres and the vehicle effectively floats, losing grip and steering response.

  30. Q30. If your car begins to aquaplane, you should:

    1. A. Brake hard immediately
    2. B. Steer sharply to the nearside
    3. C. Ease off the accelerator and keep the steering straight Correct answer
    4. D. Engage a lower gear suddenly

    Explanation. Release the accelerator, avoid braking and steering sharply, and allow speed to drop until grip returns.

  31. Q31. Driving close to the vehicle ahead is called:

    1. A. Overtaking
    2. B. Tailgating Correct answer
    3. C. Hogging
    4. D. Shadowing

    Explanation. Tailgating reduces your reaction time and is both dangerous and illegal.

  32. Q32. Why is it unwise to follow a large lorry too closely?

    1. A. It wastes fuel
    2. B. You cannot see past it and the driver cannot see you Correct answer
    3. C. It blocks your radio reception
    4. D. Your tyres will wear faster

    Explanation. Large vehicles have significant blind spots and block your view of the road ahead.

  33. Q33. When driving downhill, your stopping distance will:

    1. A. Be shorter
    2. B. Be longer Correct answer
    3. C. Stay the same
    4. D. Depend only on tyre type

    Explanation. Gravity works against braking on a descent, increasing the distance needed to stop.

  34. Q34. The best way to control speed down a long steep hill is to:

    1. A. Ride the brakes continuously
    2. B. Select a lower gear and use engine braking Correct answer
    3. C. Put the car in neutral
    4. D. Switch off the ignition

    Explanation. A low gear lets the engine help slow the vehicle, reducing brake overheating.

  35. Q35. Continuous heavy brake use on a descent can lead to:

    1. A. Better stopping
    2. B. Brake fade Correct answer
    3. C. Improved fuel economy
    4. D. Clearer vision

    Explanation. Brakes overheat and lose effectiveness — known as brake fade.

  36. Q36. In freezing conditions, how can you tell that the road may be especially slippery?

    1. A. The tyres hum loudly
    2. B. Steering feels unusually light and there is little tyre noise Correct answer
    3. C. The engine runs rough
    4. D. The wipers judder

    Explanation. Very light steering and quiet tyres are classic warnings of black ice.

  37. Q37. The safest way to brake on a slippery road is to:

    1. A. Stamp hard on the brake
    2. B. Brake gently and progressively in a straight line Correct answer
    3. C. Pump the brake rapidly while steering
    4. D. Use the handbrake

    Explanation. Gentle, progressive braking in a straight line gives the best chance of keeping grip.

  38. Q38. Cadence braking is used:

    1. A. In vehicles without ABS to keep steering control while braking hard on slippery surfaces Correct answer
    2. B. Only in automatic cars
    3. C. To warm up cold brakes
    4. D. Only when reversing

    Explanation. Cadence braking — easing on and off the pedal — helps retain steering in non-ABS cars on low-grip surfaces.

  39. Q39. Anti-lock brakes (ABS) are designed primarily to:

    1. A. Shorten stopping distances on all surfaces
    2. B. Prevent the wheels locking so you can continue to steer Correct answer
    3. C. Reduce tyre wear
    4. D. Stop the engine stalling

    Explanation. ABS keeps the wheels turning so the driver retains steering control under heavy braking.

  40. Q40. When ABS activates during emergency braking you should:

    1. A. Release the pedal immediately
    2. B. Keep firm pressure on the brake pedal Correct answer
    3. C. Pump the pedal rhythmically
    4. D. Pull the handbrake as well

    Explanation. With ABS, maintain steady firm pressure and steer around the hazard.

  41. Q41. ABS may be less effective on:

    1. A. Dry tarmac
    2. B. Loose gravel or deep snow Correct answer
    3. C. Smooth motorway surfaces
    4. D. Heated garage floors

    Explanation. On loose surfaces locked wheels can actually build a wedge that shortens stopping; ABS prevents this benefit.

  42. Q42. A fully loaded vehicle will generally:

    1. A. Stop sooner
    2. B. Need a longer braking distance Correct answer
    3. C. Handle identically
    4. D. Use less fuel

    Explanation. Extra mass increases momentum and braking distance.

  43. Q43. In thick fog you should drive:

    1. A. With full beam on and speed up
    2. B. Slowly, using dipped headlights and fog lights if visibility is under 100 m Correct answer
    3. C. Close behind the car in front to use its lights
    4. D. With hazard lights flashing

    Explanation. Reduce speed, use dipped headlights, and switch on fog lamps only when visibility is seriously reduced.

  44. Q44. When must rear fog lights be switched off?

    1. A. At night on unlit roads
    2. B. When visibility improves beyond 100 metres Correct answer
    3. C. In heavy rain
    4. D. When following another vehicle closely

    Explanation. Rear fog lights dazzle other drivers and mask brake lights when visibility is adequate.

  45. Q45. On a snow-covered road, the best approach is to:

    1. A. Use the highest possible gear and gentle controls Correct answer
    2. B. Brake sharply to test grip
    3. C. Keep the revs high in first gear
    4. D. Drive in the wheel tracks of others at normal speed

    Explanation. Pulling away and driving in a higher gear with very gentle inputs helps prevent wheel-spin and skids.

  46. Q46. If you skid because you braked too hard, the first action is to:

    1. A. Pull the handbrake
    2. B. Release the brake to let the wheels turn again Correct answer
    3. C. Steer sharply the other way
    4. D. Switch off the engine

    Explanation. Release the brake so grip returns, then steer gently to correct.

  47. Q47. Overall stopping distance is the sum of:

    1. A. Thinking distance and braking distance Correct answer
    2. B. Reaction time and speed
    3. C. Engine braking and brake pedal force
    4. D. Tyre grip and road camber

    Explanation. Overall = thinking + braking distance.

  48. Q48. At 70 mph your thinking distance alone is approximately:

    1. A. 6 metres
    2. B. 12 metres
    3. C. 21 metres Correct answer
    4. D. 38 metres

    Explanation. Thinking distance is roughly one foot per mph, so about 21 metres at 70 mph.

  49. Q49. Braking distance roughly:

    1. A. Doubles when speed doubles
    2. B. Quadruples when speed doubles Correct answer
    3. C. Halves when speed doubles
    4. D. Stays the same

    Explanation. Because kinetic energy rises with the square of speed, braking distance roughly quadruples.

  50. Q50. Tyres with low tread depth will:

    1. A. Grip better in the wet
    2. B. Increase braking distance especially on wet roads Correct answer
    3. C. Reduce tyre noise
    4. D. Last longer

    Explanation. Low tread cannot clear water, causing longer wet stopping distances and higher aquaplaning risk.

  51. Q51. The minimum legal tread depth across the central three-quarters of a car tyre is:

    1. A. 1.0 mm
    2. B. 1.6 mm Correct answer
    3. C. 2.5 mm
    4. D. 3.0 mm

    Explanation. UK law sets 1.6 mm across the central three-quarters of the tread, around the entire circumference.

  52. Q52. Which one of these will most shorten braking distance?

    1. A. Hot brake discs
    2. B. Good grippy tyres on dry tarmac Correct answer
    3. C. A heavily loaded boot
    4. D. A downhill slope

    Explanation. Good tyres on a dry road offer maximum friction for stopping.

  53. Q53. Why leave extra space when following a large goods vehicle?

    1. A. LGVs accelerate faster
    2. B. It gives you a better view past the vehicle and time to react Correct answer
    3. C. LGVs often reverse without warning
    4. D. It stops debris hitting your windscreen entirely

    Explanation. A bigger gap improves your forward view and gives time to react to anything the LGV hides.

  54. Q54. Driving at a constant distance behind a vehicle on a motorway means:

    1. A. Your relative speed is zero Correct answer
    2. B. You should flash your lights
    3. C. You must use cruise control
    4. D. You need to undertake

    Explanation. Matching speed is fine; just ensure the gap is safe for conditions.

  55. Q55. Hydroplaning risk is greatest when:

    1. A. Rain has just started after a dry spell Correct answer
    2. B. After several days of heavy rain
    3. C. On freshly gritted roads
    4. D. On new tarmac

    Explanation. Oil and rubber rise to the surface when rain first falls, dramatically reducing grip.

  56. Q56. An empty van driven in crosswinds is most affected because:

    1. A. Its wheels are narrow
    2. B. Its high sides act like a sail Correct answer
    3. C. Its engine is small
    4. D. Its mirrors are folded

    Explanation. Large flat surfaces catch gusts, pushing the vehicle off line.

  57. Q57. In heavy rain a large puddle ahead is best treated by:

    1. A. Driving through fast to clear it
    2. B. Slowing down before entering it Correct answer
    3. C. Swerving suddenly around it
    4. D. Braking hard in the water

    Explanation. Slow before you reach it; braking or swerving in standing water is risky.

  58. Q58. After driving through deep water you should:

    1. A. Increase speed to dry the brakes
    2. B. Test the brakes gently at low speed Correct answer
    3. C. Apply the handbrake hard
    4. D. Leave the engine off for a minute

    Explanation. Light braking while moving slowly dries the pads and confirms they still work.

  59. Q59. When towing a trailer, overall stopping distance will:

    1. A. Reduce
    2. B. Increase Correct answer
    3. C. Stay identical
    4. D. Only change downhill

    Explanation. Added mass and reduced braking ability on the trailer lengthen stopping distances.

  60. Q60. In freezing fog, the safest approach is to:

    1. A. Drive slower with extra following distance Correct answer
    2. B. Use full beam
    3. C. Keep hazard lights flashing
    4. D. Follow the car ahead closely for guidance

    Explanation. Reduce speed, increase gap, and use dipped headlights plus fog lamps as needed.

  61. Q61. A country lane covered in wet leaves can be as slippery as:

    1. A. Dry tarmac
    2. B. Ice Correct answer
    3. C. Concrete
    4. D. Gravel

    Explanation. Wet leaves dramatically reduce grip and should be treated like ice.

  62. Q62. In snow you should start moving in:

    1. A. First gear with high revs
    2. B. The highest gear you can manage without stalling Correct answer
    3. C. Reverse
    4. D. Neutral with the brake off

    Explanation. A higher gear reduces torque to the wheels and prevents wheelspin.

  63. Q63. When is road surface grip often at its worst in winter?

    1. A. Middle of the afternoon
    2. B. Early morning after a frost Correct answer
    3. C. Around lunchtime
    4. D. During sunshine

    Explanation. Overnight frost leaves ice that persists in shaded spots until the sun warms the road.

  64. Q64. When approaching a flooded section of road, you should:

    1. A. Accelerate to push water aside
    2. B. Check the depth, then drive through slowly in a low gear keeping revs up Correct answer
    3. C. Stop mid-way to assess
    4. D. Coast through in neutral

    Explanation. Drive slowly in low gear with steady revs to avoid stalling and water entering the exhaust.

  65. Q65. The stopping distance formula useful as a memory aid at 30 mph is:

    1. A. 3 × car length
    2. B. 3 × 23 metres
    3. C. 30 feet thinking + 45 feet braking Correct answer
    4. D. 50 metres total

    Explanation. Classic Highway Code values: 30 ft thinking + 45 ft braking = 75 ft total at 30 mph.

  66. Q66. Why are stopping distances longer in hot weather on poorly surfaced roads?

    1. A. Tyres expand
    2. B. Softened bitumen can reduce grip Correct answer
    3. C. Brakes cool faster
    4. D. Hot air is denser

    Explanation. Hot weather can melt surface bitumen, creating a slippery film.

  67. Q67. Which passenger behaviour increases thinking distance the most?

    1. A. Sitting still
    2. B. Persistent distracting conversation or arguments Correct answer
    3. C. Reading silently
    4. D. Sleeping

    Explanation. Loud or emotional interaction diverts attention and slows reactions.

  68. Q68. In very cold weather, why leave a much bigger gap to the car ahead?

    1. A. Engines run hotter
    2. B. Braking distance can be 10 times greater on ice Correct answer
    3. C. Mirrors are less effective
    4. D. Traffic moves faster

    Explanation. Ice lengthens braking distances enormously, so leave much more space.

  69. Q69. If a vehicle is tailgating you, the safest response is to:

    1. A. Brake sharply to warn them
    2. B. Gradually increase your following distance to the vehicle ahead Correct answer
    3. C. Speed up to get away
    4. D. Flash your brake lights

    Explanation. Create a larger cushion in front so you can brake gently and the tailgater has more time too.

  70. Q70. Engine braking is most useful when:

    1. A. Driving downhill to control speed Correct answer
    2. B. Stopping at a junction
    3. C. Pulling away from lights
    4. D. Reversing into a space

    Explanation. Selecting a lower gear uses engine resistance to help control speed on descents.

  71. Q71. When following a cyclist in wet weather you should:

    1. A. Overtake as quickly as possible
    2. B. Leave extra distance because their stopping ability is also reduced Correct answer
    3. C. Drive close to encourage them to move over
    4. D. Sound your horn

    Explanation. Wet roads affect cyclists too; give more space and time.

  72. Q72. Dual-carriageway speed limit for a car without trailer is:

    1. A. 50 mph
    2. B. 60 mph
    3. C. 70 mph Correct answer
    4. D. 80 mph

    Explanation. National speed limit on dual carriageways is 70 mph for cars.
