Why warn the people behind you
When you slow down or stop, the people behind you cannot always see why. A rider following closely may not notice a reduction in speed until the gap has closed, and a driver may not expect a cyclist to stop at a certain spot. A signal gives them a moment to react.
Conventions differ widely. Some countries and cycling clubs have well-known gestures, while others rely mostly on calls or have no official signal for slowing at all. Check the rules where you ride, and when riding with others, agree on signals before you set off. This article is general information and not legal advice.
Common ways to signal slowing or stopping
There is no single universal gesture. These are some commonly used ones, and your area or group may use something different.
- Arm held low, palm facing back. The arm points down and out to the side, often with the palm open towards the riders behind. In several places this is recognised as a signal for slowing or stopping.
- Hand raised. In some groups, a raised hand means “stop” or “slowing”, especially at the front of a bunch.
- Patting motion. A flat hand moved gently up and down, as if patting the air, is often used to mean “easy” or “slow down”.
- Spoken call. “Slowing”, “stopping” or “easy” is short and understood in most groups. It can be passed back along the line.
- Lights. Some riders fit lights with brake detection, which brighten when the bike slows, though this varies by product and you should follow the manufacturer’s instructions.
Because meanings are not the same everywhere, a call is often the most dependable way to back up a gesture, especially in a group or when riding with someone new.
Timing: early and smooth
The best slowing signal is one given early and followed by a gradual change of speed.
- Look first. Check behind you with a shoulder check so you know who is there.
- Signal. Make the gesture or call while the bike is steady.
- Slow smoothly. Use both brakes progressively, as covered in our notes on front and rear brake use, rather than grabbing a handful at the last moment.
- Keep your line. Avoid drifting sideways as you slow, since that makes the signal harder to read.
- Stop in a sensible place. Pull to the side, out of the way of others, before you stop completely.
Signalling too late is almost as unhelpful as not signalling. If you must stop suddenly because of an emergency, a shout and a firm, controlled stop will do more good than trying to make a neat gesture.
Hands on the bars when it matters
Slowing is often the moment you most need control. If you are braking hard, riding downhill, or crossing rough ground, keep both hands on the bars. In those cases, rely on voice, lights and a steady, predictable line. Taking a hand off to signal while you need both for the brakes is a poor trade.
One-handed riding is a skill that takes practice. Work on it in a quiet, flat, traffic-free place at a gentle speed, wearing a helmet. Our overview of cycling hand signals gives more on keeping steady when you signal.
In a group
In a bunch, slowing is a shared event, and sudden changes of speed can cause a chain reaction. Good group habits include:
- The rider at the front gives a clear call or gesture early, and everyone repeats it.
- Riders avoid braking sharply unless necessary. Easing off the pedals first often gets enough of a reduction.
- Gaps are kept steady, so the line closes up and opens gradually rather than in jerks.
- A stop is announced with enough notice that riders at the back can respond and the group can pull in together.
- The group moves off the road if stopping for a while, rather than blocking the way.
If you are new to riding in a group, the group riding guidance on this site explains the wider habits, and a leader can tell you which signals the group uses. Do not be afraid to ask.
Traffic lights, junctions and other riders
When you slow for a junction or light, a signal helps drivers behind understand you are not about to pull out or turn. If you will be stopping at the stop line, ease off early and hold a steady line. A quick glance back lets you see whether someone is close, and you can adjust your braking accordingly.
On shared paths, a raised hand or a call can alert riders behind you that you are stopping to let someone cross. Giving a short call such as “stopping” is friendlier than simply braking.
Signalling to drivers
Drivers often misread a slowing cyclist, so be cautious. They may not understand your gesture, or may assume you will carry on. Slow down early, keep a clear position in the lane, make eye contact where you can, and be ready to stop if they do not respond. A signal is a request for awareness, not a guarantee that someone will give way.
Good lights, particularly a bright rear light, help drivers notice a slowing bike in poor light. Use them as the manufacturer directs, and replace or recharge them when needed.
Alternatives if you cannot signal by hand
Some riders cannot easily take a hand off the bars, whether because of balance, injury, a disability or the bike itself. Options include voice calls, a bell, indicator or brake lights, and clear positioning. A bike shop or a qualified instructor can suggest practical solutions, and a doctor can advise about medical conditions.
Summary
- Warn the people behind you early and clearly.
- Use a gesture, a call or both, and agree signals with your group.
- Signals vary by country and club, so check local conventions.
- Keep both hands on the bars when braking hard or on rough ground.
- Slow smoothly and stop somewhere safe, out of the way.
