Why use hand signals on bicycles?

Communication on the road by bicycle goes beyond mere courtesy. It represents an invisible but essential safety shield between road users. Every gesture allows us to anticipate, warn and converse without a word, thanks to body language alone.
By clearly communicating his or her intentions, a cyclist significantly reduces the risk of collision. Car drivers, motorcyclists and other cyclists can instantly understand your upcoming movements. A hand signal transforms unpredictability into predictability, making travel smoother and safer.
These signals make up for the absence of indicators on a bicycle. They become your main communication tool, your means of alerting, informing and negotiating your path in a complex and sometimes hostile road environment.
The 6 essential cycling signals
Hand signals are a universal language between cyclists. Each gesture has a precise meaning, preventing any potential misunderstanding.
Change of direction
The most basic signal is to extend your arm in the desired direction. For a right turn, the right arm is extended horizontally. For a left turn, the left arm is raised at a right angle.
| Direction | Hand signal |-----------|--------------| | Right | Right arm horizontal | Left | Left arm at 90 degrees | Stop | Left arm extended downwards |
Complete stop
A downward movement of the hand, palm open, indicates an imminent stop. This gesture lets other road users know that you are about to slow down or stop.
Obstacle signalling
Pointing to an obstacle on the road can alert cyclists following you. A hole, pothole or piece of debris can thus be anticipated by the group.
Need to slow down
A downward and upward movement of the hand indicates the need to reduce speed. Useful in a group or during complex road conditions.
Imminent danger
A broad movement of the hand above the head signals a potential danger: an oncoming vehicle, a dangerous bend or a risky situation.
Greetings and thanks
A small wave of the hand or a nod of the head helps to create an atmosphere of respect and sharing on the road.
How to signal correctly
Precision and visibility are the watchwords. A signal must be clear, ample and anticipated sufficiently in advance to be understood by all.
Here are a few technical tips:
- Always keep one hand on the handlebars
- Signal early and clearly
- Make sure you're visible
- Maintain eye contact if possible
- Adapt your signal to your environment
