Before you get onto Singapore's public roads for the practical driving test, you have to clear the circuit — the controlled course inside your driving centre where the Traffic Police (TP) examiner checks whether you can handle the car precisely at low speed. Whether you trained at ComfortDelGro Driving Centre (CDC) in Ubi, Bukit Batok Driving Centre (BBDC), or Singapore Safety Driving Centre (SSDC) in Woodlands, the circuit stations are the same. Here is what the examiner marks at each one, and how to avoid the mistakes that send most candidates back for a retest.
How the circuit test is scored
The TP examiner uses a demerit-point system. You start with a clean sheet and accumulate points for each error. Exceed 18 demerit points across the whole test (circuit plus road) and you fail. Some circuit errors are immediate failures regardless of points — mounting the kerb, hitting a pole, or failing to stop on the slope. Every other mistake adds between two and six points, so a sloppy circuit can eat up half your budget before you even leave the centre.
The S-course
The S-course requires you to drive through a narrow, winding channel marked by kerbs without touching them. The examiner watches for:
- Smooth steering: Turn the wheel steadily rather than jerking it. Sudden corrections usually mean you entered the curve too fast or too wide.
- Speed control: Stay in first gear and use clutch control to keep the car crawling. If you brake suddenly the car can stall, which adds demerit points.
- Kerb contact: Touching any kerb with a wheel is an immediate failure. If you feel the car drifting wide, stop (if safe), straighten up, and try again — this costs a few demerit points for the stop but avoids the fail.
The key is reference points. During lessons your instructor will have shown you where to look on the bonnet or wing mirror to judge your distance from the kerb. Rehearse these until they are automatic — in the test you will be too nervous to calculate on the fly.
The crank course
The crank course is a tight right-angle channel. You drive in, make a sharp turn, and exit without hitting the kerbs or poles. The examiner is looking for:
- Correct turning point: Turn too early and your rear wheel clips the inside kerb. Turn too late and your front bumper swings into the outer pole.
- Observation: Check your mirrors and blind spot before turning, even inside the circuit. The examiner marks observation throughout.
- Recovery: If you realise you are going to hit a kerb, it is better to stop and reverse slightly than to push through. A reverse costs demerit points; hitting the kerb is an immediate fail.
Parallel parking
You must reverse into a marked bay between poles, finishing with the car straight and within the lines. The examiner checks:
- Observation before reversing: Look over both shoulders and check all mirrors before you begin moving backwards.
- Accuracy: The car must end up fully within the marked lines. A wheel touching the line is a fault; crossing it is a more serious fault.
- Number of attempts: You are allowed to adjust (pull forward and try again), but each adjustment adds demerit points. Two clean moves — one reverse turn, one straightening — is the target.
Practise at your driving centre until you can park consistently within the lines using your personal reference points (the moment the rear pole aligns with a specific point on your rear window, for example). Relying on feel alone is not consistent enough under test pressure.
Directional change
The directional change requires you to reverse into a side bay, then exit in the opposite direction. It is similar to a three-point turn compressed into a marked space. The examiner watches for:
- Steering speed: Full lock is usually needed, and you should apply it quickly once the car is moving rather than dry-steering (turning the wheel while stationary), which is a fault.
- Pole clearance: Hitting a pole is an immediate failure. Keep checking your mirrors and looking over your shoulder throughout the manoeuvre.
- Completion: You must finish with the car inside the bay and pointing in the correct direction. Leaving the car at an angle or outside the lines costs demerit points.
The slope
The slope station tests your ability to stop on an uphill gradient, hold the car on the handbrake, and move off without rolling back. This is where many candidates fail outright. The examiner marks:
- Stopping position: You must stop with your front wheels within a marked zone on the slope. Stopping before or after the zone is a fault.
- Roll-back: When you release the handbrake and move off, the car must not roll backwards at all. Even a small roll-back is an immediate failure. The technique is to bring the clutch to the biting point (you will feel the bonnet lift slightly and the engine note drop), then release the handbrake while gently adding gas.
- Stalling: Stalling on the slope adds demerit points and makes a roll-back more likely because you have to restart under pressure. If you stall, apply the handbrake immediately before restarting.
Practise the slope until you can find the biting point within two seconds every time. Consistency here is what separates a confident performance from a risky one.
General circuit tips
- Mirror checks matter: The examiner records every mirror check, even inside the circuit. Before moving off, before reversing, and before every turn, check your interior mirror and the relevant side mirror.
- Seatbelt and handbrake: Small procedural errors (not wearing your seatbelt, not engaging the handbrake when stopped) are easy demerit points. Build these into your routine so they happen without thinking.
- Stay calm at the start: The circuit is the first thing you do, and your nerves are highest. Take a breath before each station, set your reference points, and move slowly. The circuit is not timed — there is no benefit to rushing.
Practise with SteerClear
While the circuit itself is inside the driving centre, the road section that follows takes you through the surrounding streets. Use SteerClear to explore driving test routes around your test centre so you arrive at the road section already familiar with the junctions, lane markings and speed limits. The less mental energy you spend navigating unfamiliar roads, the more you have left for clean driving.
