The aim: be seen, be understood
Riding in motor traffic is a skill built on two ideas: drivers should be able to see you, and they should be able to guess what you will do next. Almost everything else, from lane position to signalling, supports one of those two.
Laws and road layouts differ by country, so treat what follows as principles and check your local rules, including which side of the road traffic uses, when you may use a full lane and what signals are required. This is not legal advice. If you are new to traffic, build up gradually from quiet streets and consider an in-person course with a qualified instructor.
Road positioning
Your position on the road affects how other road users treat you. A few general points:
- Avoid hugging the kerb. Riding in the gutter can encourage close passes, hides you from drivers at side streets and leaves you no room to avoid debris. A position a little way out from the edge, often described as a “primary” or “secondary” position in cycling guidance, can make you more visible and give you space to move. How far out is right depends on lane width, speed and local rules.
- Take more space where the lane is narrow. If a lane is too narrow for a car to pass safely within it, many cycling guides suggest riding more centrally so that drivers do not attempt a squeeze. Some riders find this uncomfortable, and it should be done calmly and with awareness of traffic behind.
- Move back to the side when it is safe and there is room for vehicles to overtake comfortably, though you are not obliged to rush.
- Hold your line. Straight and steady is easiest for others to read.
This is where the topic of road positioning can feel counterintuitive at first, because it can feel safer to hide at the edge. Experience, local advice and an instructor can help you find positions that suit you.
Be predictable
Predictability is more valuable than speed. Ride in a straight line, avoid weaving in and out of parked cars, and make decisions early. If you plan to turn, move into position well before the junction rather than at the last second. A rider who behaves consistently allows drivers to plan around them. For more on this, see predictable riding as a topic in its own right.
Signalling
Signals tell others what you intend. Typically a rider extends an arm to the side to show a turn, and many places have a signal for stopping or slowing. Check which signals are used locally. A few points:
- Signal early enough to be useful, but make sure you have enough control. If taking a hand off the bars is wobbly, practise in a quiet area first.
- Signal, then return your hand to the bars to steer and brake through the turn.
- A signal is a request or a statement of intent, not a guarantee that drivers will respond. Always check.
- Look behind before you signal or move out. A quick look over your shoulder, without swerving, is called a shoulder check, and it takes practice. Practising the shoulder check in a safe place is well worth the time.
Eye contact
Looking at drivers can help you gauge whether they have noticed you. When a car waits at a side road, look at the driver’s face if you can and watch the front wheels for movement. A nod or wave can be reassuring, but do not assume you have been seen. Many collisions involve a driver who “looked but did not see”. Slow and prepare to stop whenever a vehicle could cross your path.
Door zones
Parked cars create a hazard in the form of opening doors. Staying out of the door zone, roughly the width of a car door and a bit more from the parked vehicles, reduces the risk of a collision. This can mean riding further into the lane than feels natural. Look for people in parked cars, brake lights, indicators and hazard lights, and slow down if there is any doubt. The door zone is easy to forget when traffic is busy, so make checking it a habit.
Blind spots
Drivers have blind spots, and the bigger the vehicle, the bigger they tend to be. Lorries, buses and vans can have large areas beside and just in front of them where a rider is not visible. Good habits include:
- Do not pass a large vehicle on the side it might turn toward.
- Do not stop immediately in front of or beside a large vehicle at a light, unless you are sure the driver can see you.
- If you can’t see the driver’s mirrors, assume the driver can’t see you.
- Leave a gap when a vehicle is indicating.
Cars have blind spots too, particularly to the rear quarters.
Junctions and roundabouts
Junctions are the highest-risk places. Slow before you reach them, cover the brakes and watch turning vehicles. At roundabouts, many riders prefer to take a clear position in the lane so that cars do not try to squeeze past on the inside. If a junction feels too hard, getting off and using pedestrian crossings is a valid choice.
Lights, clothing and the bike
Use front and rear lights after dark and consider them in poor weather. Reflective or bright clothing helps. Make sure your brakes and tyres are in good shape, and have repairs done by a bike shop where needed. A helmet is a sensible precaution.
Build confidence gradually
Start on quiet streets at off-peak times, add busier roads over several weeks and notice what makes you uneasy. Over time, scanning ahead, riding predictably and keeping a margin from parked cars tend to become habits.
