IV. Light signals

Chapter 1: Regulation

Tricolor light signals

  • Are placed to the right of the roadway.
  • They can be repeated on the left or above the roadway
  • At intersections, they can be repeated on the other side of the intersection , on the left or above the roadway.

The Red light

Means prohibition of crossing the stop line or, in the absence of a stop line, the signal itself.

After the red light, the green light comes on.

The steady yellow-orange light

Means a ban on crossing the stop line, unless at the time it lights up the driver is so close to it that he or she can no longer stop in conditions of sufficient safety.

If the signal is placed at an intersection and you cannot stop without danger , you will only be able to cross the intersection if you do not endanger other users.

After the steady yellow-orange light, the red light comes on.

Traffic permitted in both directions after a one-way section of roadway.

This sign is placed in the immediate vicinity of the danger and not 150 meters away.

The green light

Means authorization to cross the signal and continue on your way.

After the green light, the steady yellow-orange light comes on.

The tricolor arrows

Have the same meaning as circular traffic lights, but their effect is limited to the directions indicated by the arrows.

In this photo, drivers can cross the signal and continue their route towards the directions indicated by the green arrows without giving way 

A red light lit with a green arrow

Means  authorization to continue  walking  only in the directions indicated by the arrow  , provided that  you give way to users  regularly coming from other directions and to pedestrians.

When there is a cycle path, this signal  also concerns moped drivers who are authorized to travel.


The illuminated lights of a bicycle

Light signals with the silhouette of a bicycle only concern drivers of bicycles and two-wheeled mopeds .

Les feux éclairés d’une bicyclette entourée de flèches

Cela signifie que le feu est simultanément au vert, à l’orange-fixe ou au rouge pour tous les cyclistes dans le carrefour.

Lorsqu’il y a une piste cyclable, le feu concerne aussi les cyclomoteurs qui sont autorisés d’y circuler.

The tricolor crosses

Informs you at certain intersections about the color of the light of drivers coming in the opposite direction who you must cut across to turn left.

Two-color light signals for pedestrians

The Red light

Means the prohibition to enter the roadway.

The green light

Means authorization to enter the roadway. 

As an indication, the end of this authorization can be announced by flashing the green light.

A pedestrian’s light surrounded by arrows

Means that the light is simultaneously green or red in the intersection.


Two-color light signals at a level crossing

A flashing white lunar light placed at level crossings

Means authorization to cross the signal.

Two alternately flashing red lights placed at level crossings

Means for all users the prohibition to cross the stop line or if there is no stop line, the signal itself.

Light signals above traffic lanes

Lights in the form of a red cross

Indicate the prohibited direction on the tape.

Lights in the form of green arrows pointing downwards

Indicate the  lanes open in your direction  of travel.

Flashing orange lights

flashing yellow-orange light authorizes you to cross the signal with extra caution but it does not change the rules.

If the light is placed at the intersection and is not accompanied by any signal relating to priority, you must give priority to drivers coming from the right.

A yellow-orange light placed alone or two lights lighting alternately

yellow-orange light that flashes in the middle of the three-color system when this entire system is not working, obligation to give priority to pedestrians who intend to cross on the pedestrian crossing.

A light that flashes instead of a green light in the operation of the three-color system. You must not give way to pedestrians who intend to enter the pedestrian crossing because they have a red light.

In the event that there is a  flashing orange light and a Stop signal,  you must first  stop, give way  to the left and right and then move on.


In the event that there is a flashing orange light and a signal indicating that right priority is applicable in the intersection, priority must be given to drivers coming from the right.

In the event that there is a flashing orange light and a signal indicating priority at the intersection, the driver has priority and can proceed without delay.

Lights specific to public transport vehicles

A horizontal bar

Illuminated with a white light on a black background means it is forbidden to cross the stop line or, in the absence of a stop line, the signal itself.

It is the equivalent of a red light .

A circle

Illuminated with white light on a black background, is equivalent to a fixed orange light.

A triangle on point

Illuminated with white light on a black background, is equivalent to a green light.

Oblique lights

These lights are the equivalent of arrow-shaped lights.
