Prohibitory traffic signs are used to prohibit certain types of manoeuvres or some types of traffic.

Prohibitory traffic signs

No entry

This sign is used to indicate that no vehicles may enter; however, it often will not apply to pedestrians as well as pushed bicycles unless signalled otherwise.

Speed limits

Used to indicate either a minimum or maximum speed limit, or, in Germany, a recommended speed limit.

No parking

Amongst one of the most familiar signs, this sign is used where parking or stopping should be prohibited.

No overtaking

Either overtaking is prohibited for all vehicles or certain kinds of vehicles only (e.g. lorries, motorcycles, etc...)
