Traffic lights are essential elements of road signalling that regulate traffic and ensure the safety of all road users. They come in different shapes and colours, each with a precise meaning that every driver must know and respect.

Traffic lights

The red light

The red light means an absolute prohibition on crossing the stop line or, in the absence of a stop line, the signal itself. It is followed by the green light.

The steady amber light

The steady amber light means it is forbidden to cross the stop line, unless the driver is too close to stop safely. At a junction, if stopping is dangerous, you may proceed without endangering other road users. It is followed by the red light.

Three-colour arrows

Three-colour arrows have the same meaning as circular three-colour traffic lights, but their effect is limited to the directions indicated by the arrows. Drivers may pass the signal in the direction of the green arrows without giving way.

Red light with green arrow

A red light with a green arrow means permission to proceed only in the directions shown by the arrow, while giving way to other road users and pedestrians. For cycle paths, this signal also applies to authorised moped riders.

Traffic lights for cyclists

Traffic lights showing a bicycle silhouette apply only to cyclists and riders of two-wheeled mopeds. When the silhouette is surrounded by arrows, the light is simultaneously green, steady amber or red for all cyclists at the junction.

Two-colour traffic lights for pedestrians

The red light means it is forbidden to step onto the carriageway. The green light permits stepping onto the carriageway, with the possibility of flashing to signal the end of the permission period. A pedestrian surrounded by arrows indicates that the light operates simultaneously throughout the entire junction.

Signals at level crossings

A flashing white lunar light permits crossing. Two alternately flashing red lights mean crossing is forbidden for all road users.

Signals above traffic lanes

Green downward-pointing arrows indicate lanes open in your direction. Red crosses indicate that the lane is closed to traffic in your direction.

Understanding and obeying traffic lights is fundamental to road safety. Whether it is the standard three-colour lights, specific signals for cyclists and pedestrians, or lights at level crossings, every driver must be able to correctly interpret these signals and adapt their behaviour accordingly.
