Leaving enough room in front of you gives you time to react and stop if the vehicle ahead brakes suddenly.
It also makes driving calmer and saves fuel by reducing harsh braking.
The two-second rule
Watch the vehicle ahead pass a fixed point, such as a sign. Count “one thousand and one, one thousand and two.” If you pass the point before you finish, you are too close.
Increase it when
- ▸Roads are wet — at least double the gap
- ▸Ice or snow — up to ten times the gap
- ▸Towing or driving a heavy vehicle
- ▸Visibility is poor
- ▸Following motorcycles or large vehicles
If someone tailgates you
Do not brake-check. Gradually leave more space in front so you can slow down gently, and let them pass when safe.
Driver assistance
Adaptive cruise control can maintain a set gap, but it is not a replacement for attention. Choose a longer gap setting, especially in poor weather.
