HOW DO YOU SIGNAL ON A BIKE?

By Anthony WalshRoadman CyclingUpdated 10 July 2026

ANSWER

6 hand signals cover every common road situation: right arm extended for a right turn, left arm extended for a left turn, right hand behind the back pointing left for a group-riding pull-off, hand waving behind the back for hazard warning, palm down behind the back for slowing, and pointing downward at a road hazard. These should be combined with verbal calls — 'car back', 'hole', 'slowing', 'stopping', 'clear' — which are essential in group riding and racing. Signal early, hold the signal for 3-5 seconds, and return your hand to the bars before the manoeuvre, not during it.

KEY TAKEAWAYS

Signal turns by extending the arm in the direction you intend to turn — right arm for right, left arm for left.
Point down at road hazards (potholes, glass, gravel) with the hand on the same side as the hazard so riders behind can see and avoid it.
Verbal calls ('car back', 'slowing', 'hole left') are as important as hand signals in group riding — signals can be missed, calls carry further.
Signal early and return your hand to the bars before turning, braking, or negotiating the hazard — you need both hands for control during the manoeuvre itself.

WHO THIS IS FOR

IS THIS YOU?

New cyclists learning road skills and group riding etiquette

You have started riding on the road or joined a cycling club and want to know the standard hand signals and verbal calls used by experienced riders.

Solo riders preparing to join group rides or sportives

You are comfortable riding alone but have not ridden in a group and want to learn the communication system before your first club run or event.

THE ROADMAN VIEW

Signalling is one of those basic cycling skills that experienced riders take for granted and new riders are often never properly taught. It is not complicated — there are six hand signals that cover everything — but getting them right matters for your safety and the safety of everyone around you. In a group ride, a pothole that you ride around without signalling becomes a pothole that the rider behind you hits at 35 km/h because they could not see it past your wheel. That is how people crash. Signalling is not optional politeness; it is a safety practice.

The verbal calls are equally important and often overlooked. Hand signals work when the rider behind is looking at you, but they miss them if they are glancing at their computer or looking up the road. A clear shout of 'hole left' or 'car back' cuts through in a way that a hand signal cannot. On Roadman group rides, the expectation is that calls are passed back through the group — each rider relays the call rearward. If the front rider calls 'car up' and only the first three riders hear it, the back of the group is still riding two abreast into oncoming traffic. Communication keeps everyone safe.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Chris Boardman MBEOlympic gold medallist, former British Cycling policy adviser, Active Travel Commissioner
Clear, consistent signalling is the foundation of safe cycling on shared roads. Research into driver-cyclist interactions shows that early, obvious hand signals significantly increase the likelihood that drivers anticipate and accommodate a cyclist's manoeuvre. The key is predictability — signal early, hold the signal long enough to be seen, and then execute the manoeuvre smoothly. Drivers respond to cyclists who communicate their intentions clearly.

PRACTICAL APPLICATION

DO THIS WEEK

Learn the six essential hand signals and practise them on quiet roads
Right turn: right arm extended horizontally. Left turn: left arm extended horizontally. Hazard: point down at the obstacle with the hand on the same side. Slowing: open palm facing rearward, moved up and down behind your back. Pulling off (group riding): right hand behind the back, waving left to indicate the rider behind should come through. Stopping: closed fist behind the back or arm extended with palm facing rear. Practise signalling while maintaining a straight line on a quiet road.
Add verbal calls to match every hand signal in group riding
Pair each signal with a verbal call: 'right' or 'left' for turns, 'hole left/right' for hazards, 'slowing' or 'stopping' for pace changes, 'car back' for traffic approaching from behind, 'car up' for oncoming traffic, 'clear' at junctions. Speak loudly and clearly — mumbled calls are useless. Relay calls rearward through the group so the back riders hear them.
Time your signals: early enough to warn, hands back before the action
Signal 30-50 metres before a turn, 10-20 metres before a hazard, and immediately when you start slowing or stopping. Hold the signal for 3-5 seconds so following riders and drivers have time to process it. Return your hand to the bars before you execute the turn or braking — you need full control during the manoeuvre itself, not during the signal.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKESignalling at the last moment, leaving no reaction time for following riders or drivers.
FIXSignal at least 30 metres before a turn and 10 metres before a hazard. The purpose of the signal is to give others time to anticipate and react. A signal given during the manoeuvre itself is too late to be useful.
MISTAKEOnly using hand signals and not adding verbal calls in group rides.
FIXHand signals can be missed if a rider behind is looking elsewhere. Verbal calls cut through noise and distraction and reach further back in a group. Use both together for maximum communication, and relay calls rearward through the group.
MISTAKEKeeping a hand off the bars through a turn or over a hazard.
FIXSignalling through a turn or while riding over a hazard compromises your control and balance. Signal before the manoeuvre, return both hands to the bars, and then execute the turn or avoid the hazard with full control of the bike.

FAQ

FREQUENTLY ASKED QUESTIONS

Is it a legal requirement to signal on a bike in the UK?

The Highway Code recommends signalling before turning, but there is no specific legal penalty for failing to signal on a bicycle. However, failing to signal could be considered careless cycling under the Road Traffic Act if it contributes to a collision. Beyond legality, signalling is essential for your safety and the safety of other road users.

How do I signal if I am not confident riding with one hand?

Practise riding with one hand on a quiet road or cycle path. Start by briefly lifting one hand while riding in a straight line, then progress to extending it fully. If you struggle, your bike handling may benefit from general skills work — try riding slowly, cornering at low speed, and track-standing to build confidence and balance before adding one-handed riding.

What verbal calls should I know for group rides?

The essential calls are: 'car back' (vehicle approaching from behind), 'car up' (oncoming vehicle), 'hole' or 'hole left/right' (road hazard), 'slowing' (group reducing speed), 'stopping' (group stopping), 'clear' or 'not clear' (at junctions), and 'on your right/left' (overtaking another cyclist). These are standard across most UK cycling clubs.
