The challenge: signalling without losing control

A turn signal asks you to take one hand off the handlebars at exactly the moment when many things are happening: traffic, a corner, perhaps a need to brake. That is why this is both useful and slightly tricky. A clear signal tells others what you intend, but it only helps if you stay in control.

Signalling conventions vary by country, so check local guidance. This article focuses on the handling skill, not the rules. Riding with one hand is a risky skill for beginners, so learn it gradually in a safe, flat, traffic-free place, wearing a helmet.

The basic idea

Most turn signals follow a simple pattern: extend the arm on the side you plan to turn towards, hold it long enough to be seen, then return the hand to the bars before you make the turn. In some places a bent arm held upwards is also used for right turns. Whichever you use, the sequence is the same:

  1. Look. Check behind with a shoulder check so you know what is there.
  2. Signal. Extend your arm clearly, ideally for a few seconds, while the bike is steady.
  3. Look again if needed. See whether anyone has responded or slowed.
  4. Hands back on the bars. Put both hands on the bars before you start to turn or brake.
  5. Turn. Take a smooth, predictable line.

If you are unsure of the right sequence at a junction, our notes on junction etiquette cover positioning and timing.

Keeping the bike steady with one hand

A bike is surprisingly stable at a moderate speed, but taking a hand away changes how it feels. A few simple habits help:

  • Stay relaxed. Keep your grip on the other hand light but secure, and bend your elbow slightly. Stiff arms transmit every bump to the steering.
  • Look where you want to go. Your eyes help keep a straight line. Looking at the road ahead, not at your hand, keeps you steady.
  • Keep pedalling or coast smoothly. Sudden changes in speed can unbalance you.
  • Use your body. Keep your weight centred and your hips level, rather than leaning towards the arm you are extending.
  • Keep your fingers near the brake. If your free hand covers a brake lever, you can return quickly. Remember that on many bikes the brake you need is on the hand you are using to hold the bars, so know which lever is where.
  • Signal on smooth ground. Avoid signalling over cracks, gravel, wet leaves or cobbles.

Understanding how your bike behaves at slow speeds and how to handle one-handed riding more generally can make signals less nerve-racking, but only add one-handed riding in small steps and stop if it feels uncomfortable.

Practising safely

Practice makes the movement automatic. Choose a quiet, flat, traffic-free area, such as an empty car park, and wear a helmet and suitable protection.

  1. Ride slowly in a straight line and lift your hand just off the bar, then put it back.
  2. Gradually extend the arm for a couple of seconds, keeping your eyes ahead.
  3. Repeat on both sides. You may need either arm on the road.
  4. Add a shoulder check before the signal, then practise the full routine.
  5. Increase speed only as it feels comfortable.

If your bike wobbles, slow down and go back a step. Some people find one side easier than the other. That is normal, and it is worth working on the weaker side without rushing.

When to keep both hands on the bars

Sometimes the best signal is no hand signal at all. Keep both hands on the bars when:

  • the road is rough, wet, icy, gravelly or full of holes
  • you are going downhill or need to brake
  • you are in a tight space or close to other riders or pedestrians
  • you are carrying a load, a child seat or a trailer that affects steering
  • you feel tired, nervous or unsteady
  • strong wind or a crosswind is pushing the bike around

In these situations, other ways of communicating help. Slow down early, take a clear line and make eye contact with drivers. A call or the bell can also help in some cases. Lights fitted with indicators or a flashing rear light make you easier to see, although none of these remove the need to check the way is clear.

Timing and position

Good timing makes a signal more effective. Signal early enough that others can respond, but not so early that your meaning becomes unclear, for instance by signalling a left turn long before the junction you are aiming for. If there are junctions close together, signal for the one you intend to take and consider waiting until you have passed the earlier one.

Position matters too. Signal from a stable position in your lane, and avoid swerving to make the turn. If you need to move across the road to turn, signal first, check behind, and move gradually.

What if the signal is not seen

You cannot control whether others notice. Assume they might not. A driver may be distracted, or a pedestrian may be wearing headphones. Slow down, watch for movement, and be prepared to give way. A signal is a request for space, not a right to take it.

If someone responds by slowing or leaving a gap, a quick nod or wave in thanks is a simple courtesy.

If you cannot signal with a hand

Not everyone can signal comfortably with an arm, whether because of balance, an injury, a physical condition or the bike itself. That is fine. Alternatives include using a bell or voice, positioning clearly, using indicator lights if fitted, and choosing quieter routes with simpler turns. A bike shop or a qualified instructor can suggest options, and a doctor can advise if a medical condition is involved.

Summary

  • Look, signal, hands back on the bars, then turn.
  • Practise one-handed riding in a safe, flat, traffic-free place.
  • Skip the arm signal on rough ground, during braking or when unsteady.
  • Back signals up with positioning, eye contact and lights.
  • Check local rules for the signals expected where you ride.
