HOW TO RIDE A BIKE IN TRAFFIC?

By Anthony WalshRoadman CyclingUpdated 10 July 2026

ANSWER

Safe cycling in traffic rests on three principles: road positioning that makes you visible and asserts your space, predictable behaviour that communicates your intentions to drivers, and situational awareness that anticipates hazards before they materialise. Research by Dr John Parkin at the University of the West of England shows that cyclists riding 1.0-1.5 metres from the kerb receive safer overtaking passes — averaging 40 cm wider — than those hugging the gutter. Taking a primary position (centre of lane) at junctions, roundabouts, and pinch points prevents dangerous close passes. Predictability — clear hand signals, smooth lane changes, consistent speed — reduces conflict with motor vehicles by allowing drivers to anticipate your movement.

KEY TAKEAWAYS

Ride 1.0-1.5 metres from the kerb — this forces wider, safer overtaking passes.
Take primary position (centre of lane) at junctions, roundabouts, and where the road narrows.
Signal clearly and early — drivers need 3-5 seconds to process your intention.
Assume you have not been seen until you have made eye contact with the driver.

WHO THIS IS FOR

IS THIS YOU?

The new commuter

You have started cycling to work and feel nervous sharing the road with motor vehicles.

The rural rider coming to the city

You are comfortable on quiet lanes but anxious about urban traffic.

The returning cyclist

You have not ridden in traffic for years and want to rebuild confidence with current best practice.

THE ROADMAN VIEW

Traffic riding is a skill, not a gamble. Riders who position themselves correctly, communicate clearly, and read the road are overwhelmingly safe. The ones who get into trouble are usually either too far left — hugging the gutter where they are invisible and have no room to manoeuvre — or too unpredictable, weaving between lanes without signalling.

The single most important rule: own your space. Riding 1.0-1.5 metres from the kerb feels counterintuitive at first because it puts you further into the lane. But the data is clear: drivers give you wider passes when you are visible and central. When you hug the gutter, drivers try to squeeze past without moving out, and that is where the close passes happen.

At junctions and roundabouts, take the centre of the lane. This makes you unavoidable in a driver's field of view and prevents them from turning across you. Yes, it means the car behind waits. That is the point — they can see you, and they pass when it is safe.

EXPERT EVIDENCE

WHAT THE EXPERTS SAY

Dr John ParkinTransport engineering researcher, University of the West of England
Cyclists riding 1.0-1.5 metres from the kerb receive overtaking passes that are on average 40 cm wider than those riding in the gutter position. The primary road position (centre of lane) at junctions eliminates the left-hook collision pattern, which accounts for a substantial proportion of serious cyclist injuries.
Dr Ian WalkerTraffic psychology researcher, University of Bath
Driver behaviour studies show that overtaking distance is influenced by cyclist positioning more than any other variable, including helmet use or hi-vis clothing. Drivers make subconscious judgements about available road width — a cyclist positioned further into the lane forces drivers to make a conscious overtaking decision rather than squeezing past on autopilot.

PRACTICAL APPLICATION

DO THIS WEEK

Ride 1.0-1.5 metres from the kerb
This position makes you visible in wing mirrors, avoids drain covers and debris, and forces overtaking drivers to move into the next lane. Practise on quiet roads first until the position feels natural.
Take primary position at hazard points
Move to the centre of the lane at junctions, roundabouts, traffic lights, road narrowings, and parked cars. This prevents drivers from attempting unsafe passes at pinch points. Move back to the secondary position (1.0-1.5 m from kerb) on open road.
Signal clearly and make eye contact
Signal turns 3-5 seconds before you make them. At junctions, look at the driver and establish eye contact — if they have not seen you, assume they will pull out. Point to where you are going, not just left or right.
Scan constantly and plan escape routes
Check behind you every 10-15 seconds with a quick head turn or mirror. Look through the windows of parked cars for occupants about to open doors. Identify escape space on your left in case a vehicle encroaches.

COMMON MISTAKES

WHAT CYCLISTS GET WRONG

MISTAKERiding in the gutter to let traffic pass.
FIXGutter riding makes you invisible and leaves no room to avoid hazards. Hold 1.0-1.5 metres from the kerb and let drivers overtake properly.
MISTAKEFiltering on the left side of large vehicles.
FIXNever pass a lorry, bus, or HGV on the left (nearside) — the blind spot is enormous and left-turning vehicles are the most dangerous collision pattern for cyclists. Wait behind or pass on the right.
MISTAKEWearing headphones in traffic.
FIXHearing is a critical sense for traffic awareness. Engine noise, horns, and tyre sounds provide early warning of approaching vehicles. If you use earphones, use a single bone-conduction unit at low volume.

FAQ

FREQUENTLY ASKED QUESTIONS

Is hi-vis clothing necessary?

Hi-vis clothing increases detection at distance but does not prevent close passes. Road positioning has a larger effect on driver behaviour than clothing colour. That said, fluorescent yellow in daylight and reflective materials at night are sensible additions to good positioning.

Should I use a mirror?

Bar-end or helmet-mounted mirrors reduce the need for backward glances, which can cause wobble. They are useful in heavy traffic but do not replace shoulder checks — mirrors have blind spots. Try one and see if it suits your riding style.

How do I deal with aggressive drivers?

Do not engage. Do not shout, gesture, or chase. Note the registration number if possible and report dangerous driving to the police via dashcam or helmet camera footage. Your safety is worth more than being right in the moment.

Is a helmet camera worth it?

Helmet or bar-mounted cameras provide evidence in the event of a collision or near miss. Several UK police forces accept camera footage for prosecution of dangerous driving. The camera may also subtly alter driver behaviour when visible.

When should I use cycle lanes?

Use cycle lanes when they are well-maintained and free of debris, parked cars, and pedestrians. You are not legally required to use them in the UK. If a cycle lane feels unsafe — narrow, poorly surfaced, or full of hazards — ride in the main carriageway.

How do I handle roundabouts?

Take primary position (centre of the lane you need) before entering. Signal your exit clearly. On multi-lane roundabouts, position yourself in the correct lane for your exit — do not hug the inside if you are going straight on or right. Make eye contact with drivers waiting to enter.
