BDifficulty 2/5

You drive a car on a dual carriageway outside a built-up area, with two lanes in your direction, outside tunnels. You follow a lorry without intending to overtake. What gap must you keep to be able to stop without collision if the lorry brakes sharply?

Correct answer

The safety gap that allows stopping without collision.

A safety gap appropriate to speed, grip and braking ability. This case does not require a fixed 50 metres or automatically apply the tunnel rule of 100 metres or four seconds. With two lanes in the same direction, the additional space intended to let a following vehicle overtake under Article 54 is not required. The necessary gap may increase with rain, load or poor grip.
