It's one of those habits that creeps in quickly — you're running late, traffic is moving slower than you'd like, and before you know it, you're sitting just a car's length behind the vehicle in front. Tailgating is one of New Zealand's most common — and most dangerous — driving behaviours. For learner drivers, understanding following distance isn't just about passing your practical driving test. It's about building a habit that keeps you safe for life.
The Two-Second Rule (and When to Double It)
Waka Kotahi NZTA recommends the two-second rule as a minimum following distance in dry conditions. Here's how it works: when the vehicle ahead passes a fixed point — a road sign, a shadow, a crack in the road — count two full seconds before you reach the same point. If you get there before you finish counting, you're too close.
But two seconds is a bare minimum. In adverse conditions, you should increase your following distance significantly:
- Wet roads: Double it to at least four seconds. Water reduces tyre grip dramatically, and braking distances increase.
- Gravel or unsealed roads: Four seconds or more. Loose surfaces are unpredictable and stones can flick up and damage your windscreen.
- Foggy or low-visibility conditions: Increase distance so you can stop safely within the distance you can actually see.
- Following heavy vehicles or trucks: Increase your gap — large trucks take much longer to stop, and their size blocks your view of the road ahead.
- Towing a trailer: Your own stopping distance increases, so give yourself extra room.
Why Your Brain Underestimates the Risk
Here's something that surprises many new drivers: at 100 km/h, you're travelling about 28 metres every second. Even with a perfectly alert reaction time of 1.5 seconds, you'll cover over 40 metres before your brakes even begin to bite — and then you need the braking distance on top of that. On a wet road, total stopping distance from 100 km/h can exceed 100 metres.
The problem is that close following feels normal when everyone around you is doing it. Our brains adapt to the visual flow of traffic and stop registering how little space we actually have. This is sometimes called "speed adaptation" — and it's a real psychological trap for new drivers.
Following Distance During Your Practical Driving Test
Your examiner will be watching your following distance throughout the test. Sitting too close to the vehicle in front is considered a fault, and repeated instances or a single dangerous moment can result in a failed test. Examiners want to see that you're scanning ahead, leaving appropriate gaps, and adjusting your distance as conditions change.
A useful trick: if you can't see the rear tyres of the vehicle in front touching the road, you're almost certainly too close — especially when stopped at traffic lights.
The Motorway Problem
Following distance tends to collapse most on motorways, where speeds are high and drivers fall into a convoy-like rhythm. In New Zealand, motorway driving is assessed as part of many practical test routes in cities like Auckland, Wellington, and Christchurch. Practising on real test routes — including motorway sections — helps you build the awareness to maintain safe gaps even when traffic pressure makes it feel uncomfortable.
Apps like SteerClear let you practise on actual NZ practical driving test routes with live scoring, so you can identify where your following distance habits tend to slip before your real test day.
Make Space a Habit, Not an Afterthought
Safe following distance is ultimately about giving yourself options. The more space you have in front of you, the more time you have to react, adjust, and avoid a collision. Tailgating removes those options entirely.
Whether you're preparing for your practical driving test or just starting to build your skills on the road, commit to the two-second rule from day one. It's one of the simplest habits you can form — and one of the most powerful ways to protect yourself and everyone around you.
