When travelling behind another vehicle, you must leave a gap that allows you to stop, in the event of sudden braking, without colliding with it, taking into account the speed and the conditions of grip and braking. Furthermore, if you are travelling without signalling your intention to overtake, this gap must allow the vehicle behind you to overtake safely. In the specific case of vehicles with a maximum authorised mass exceeding 3,500 kilograms and vehicles and vehicle combinations more than 10 metres in total length, these must maintain a minimum separation of 50 metres. The obligation to maintain this distance to allow overtaking shall not apply in the following situations: - In built-up areas. - Where overtaking is prohibited. - Where there is more than one lane designated for traffic in the same direction. - When traffic is so congested that overtaking is not possible.
