The Instinct That Makes Things Worse

New cyclists in traffic almost universally do the same thing: they ride as far to the right as physically possible — or left, depending on the country — hugging the kerb, trying to take up as little space as they can. It feels polite and it feels safer.

It’s the opposite of safer. Riding in the gutter puts you in the debris and drain covers, out of drivers’ natural line of sight, and — most importantly — it invites vehicles to overtake in situations where there genuinely isn’t room, because from the driver’s seat it looks like there might be.

Almost all urban cycling safety comes down to two things: where you position yourself, and how predictable you are. Neither requires fitness or fast reactions.

The Two Positions

Experienced cyclists talk about two default road positions, and switching between them deliberately is most of the skill.

The secondary position — roughly a metre out from the kerb, or from parked cars. This is the default on a wide, clear road where drivers can overtake you properly with room to spare. It leaves you an escape space toward the kerb and keeps you out of the gutter debris.

The primary position — in the middle of the lane, where a car’s right-hand wheel track would be. This is not aggressive and it is not “taking up the road.” It’s the correct position whenever it would be dangerous for a vehicle to overtake you within your lane, and it works because it makes the situation unambiguous: a driver behind you can see there’s no room and waits.

Use the primary position when:

  • The lane is too narrow for a car to pass you safely
  • Approaching and going through junctions and roundabouts
  • Passing parked cars, side roads, or anywhere a vehicle might pull out
  • Riding downhill at close to traffic speed
  • Anywhere visibility is limited — bends, brows of hills
  • Any time you’d rather not be overtaken right now

Move back out to secondary when the road opens up and passing is genuinely safe. Moving between the two deliberately, with a shoulder check first, communicates far more to drivers than staying rigidly in one.

The Door Zone

Parked cars deserve their own rule, because being hit by an opening door is one of the most common serious urban cycling injuries — and it’s entirely avoidable.

A car door extends roughly a metre. Ride at least that far out from any line of parked cars, all the time, without exception, even when it feels like you’re taking too much space. You cannot see whether someone is sitting in a parked car, you cannot predict when a door opens, and you have no time to react at cycling speed.

If the road is too narrow to ride outside the door zone and still leave overtaking room, then it’s too narrow to be overtaken on. Take the primary position and hold it.

Junctions Are Where Things Actually Happen

The large majority of collisions between bikes and vehicles happen at junctions, not on open stretches. Two patterns account for most of them.

The left/right hook — a vehicle overtakes you and then immediately turns across your path into a side road or driveway. The defence is positional: as you approach a junction, move out into the primary position so you’re not overtakeable at exactly the moment a driver might turn across you. Never ride up the inside of a large vehicle that could be turning, particularly a lorry or bus.

The pull-out — a driver waiting at a side road looks for cars, doesn’t register a bicycle, and pulls out. The defence is visibility and speed control: assume you have not been seen until you have eye contact, cover your brakes, and be ready to stop. Being further out in the lane genuinely helps here, because you enter a driver’s field of view sooner.

At multi-lane junctions, get into the correct lane for your direction early, exactly as a car would, having checked over your shoulder and signalled. Turning right from a left-hand lane at the last second is where cyclists surprise drivers.

Signal, Look, and Look Again

Shoulder checks are the fundamental skill, more than signalling. Before any change of position — moving out around a parked car, taking the lane, changing lanes — look behind you first. It’s the single most useful habit in traffic, and it does something beyond gathering information: turning your head visibly tells the driver behind you that you’re aware and about to do something.

Practise until you can look behind without swerving. On a quiet road, ride in a straight line beside a painted line and look over your shoulder repeatedly until the bike stops wandering.

Signal clearly and early, then put your hand back on the bars before you need to brake or turn. A signal given while already turning is decoration.

Make eye contact at junctions. A driver who has looked at you and a driver who has looked through you behave very differently, and you can usually tell which is which.

Being Seen

Visibility is a system, not one item.

Lights, day and night. A rear light and a front light, running in daylight too. Flashing modes are more attention-grabbing but harder to judge distance from — many riders run one steady and one flashing to get both.

Reflectives beat fluorescents at night. Fluorescent yellow works in daylight and does nothing after dark. Reflective material on your ankles and feet is disproportionately effective, because the up-and-down motion of pedalling is instantly recognisable as a person on a bike from a long way off.

Position is visibility. A cyclist in the middle of a lane is in a driver’s central vision. A cyclist in the gutter is in their peripheral vision, competing with parked cars and street furniture.

None of this makes you invulnerable, and the responsibility for safe overtaking is the driver’s. But the goal isn’t fairness — it’s arriving.

Predictability Over Speed

The strongest single principle: be boring. Ride in a straight line. Hold your position rather than weaving between parked cars and back out. Don’t undertake queuing traffic on the inside where drivers don’t look. Don’t jump between the road and the pavement. Stop at red lights — beyond the legal point, running them destroys the predictability that everything else depends on, and it recalibrates how the drivers around you expect cyclists to behave.

A driver who can guess what you’re about to do will give you room. A driver who can’t will make their own guess, and they’ll make it at forty kilometres an hour with a metal box around them.

The Route Matters More Than the Riding

Finally, the easiest safety improvement available: don’t ride the route you’d drive. The fastest car route is usually the widest, busiest, fastest road — the worst possible choice on a bike.

Spend twenty minutes with a cycling-specific route map, and look for parallel residential streets, cycle paths, park routes, and canal towpaths. A commute that’s three minutes longer and runs mostly on quiet streets is a commute you’ll still be doing in a year.
