Minimum distance between vehicles
Prohibitory and restriction signs

Minimum distance between vehicles

Keep at least the distance shown from the vehicle ahead.

Vehicles covered by the sign must maintain the stated gap from the vehicle ahead. Leave more space when conditions require it.

A common design shows two vehicles and a distance figure inside a red-bordered circle. France uses B17. Germany’s 273-70 applies to specified heavy vehicles and tractors.

How it looks in each country
