Riding in traffic: why drivers miss you, and how to ride so they don't

The most dangerous moment on a scooter usually isn’t a mistake you make — it’s a driver who looks straight at you and pulls out anyway. Understanding why that happens is the first half of riding safely in traffic; positioning yourself so it can’t is the second. Here is both. For depth, see our defensive-riding guide, and pair it with being seen.

Why drivers genuinely don’t see you

It is not (always) carelessness — it is how vision works. When a driver scans a junction, their eyes briefly switch off during each movement (saccadic masking), so the scene is only captured during the stationary pauses, leaving gaps the brain fills in (Science of Being Seen) — and a small, fast rider can fall into a gap. Even when they do see you, they may not remember: drivers fail to report an approaching motorcycle on 13–18% of occasions because later visual input overwrites the memory — the “saw but forgot” error (Shahar et al., PMC 2019). And they are not looking for you in the first place: in one experiment 65% of drivers missed a motorcycle versus 31% who missed a taxi in the same spot (Association for Psychological Science). Your small profile even distorts their timing — the size-arrival effect makes the brain judge smaller objects as farther away, so a driver misjudges when you’ll reach the junction (ScienceDaily, 2013).

Junctions are where it happens

All of that concentrates at intersections. Crash data show more than 25% of fatal motorcyclist crashes involve another road user moving into the rider’s path, typically at a junction, with a driver scanning error contributing in 63% of two-wheeler-vs-vehicle crashes (Shahar et al., PMC 2019). For pedal cyclists, 28% of 2023 US fatalities were at intersections (NHTSA, Traffic Safety Facts 2023), and a British study found intersections carried roughly 3.4 times the injury odds of non-intersection sites (Aldred et al., BMC Public Health, PMC 2021). The takeaway: treat every junction as the high-risk event it is — slow down, cover the brakes, and never assume you’ve been seen.

Own your lane

Hugging the kerb feels safer; it isn’t. Our defensive-riding guide covers the primary position in detail — riding in the centre of the lane, where a car would be — at pinch points, traffic lights and roundabouts, because it makes you visible and predictable and discourages risky overtakes (Cycling UK). The UK Highway Code codifies it: ride in the centre of the lane to be as visible as possible on quiet roads, at junctions and at narrowings, and keep at least 0.5 m from the kerb on busier roads (UK Highway Code, rules 72–82). Claim the space you need to be seen and to have somewhere to go.

Stay out of the door zone

Parked cars hide a specific trap. The Highway Code says leave a door’s width — about 1 metre — when passing parked vehicles (UK Highway Code, rules 72–82), because an opening door is a wall that appears with no warning. The risk is bigger than it looks: the door zone is roughly a four-foot band along parked cars, and “dooring” is estimated to cause 12–27% of urban car–bike collisions (Active Transportation Alliance). Ride outside it, even if that means taking the lane.

A system, not just luck

Good riders run a routine. The Motorcycle Safety Foundation’s SEE method — Search, Evaluate, Execute — means actively scanning for risk factors, judging how they could interact, then acting early (Motorcycle Safety Foundation). Build in the defensive habits MSF courses teach: keep a space cushion, identify escape routes, and cover your brakes entering any junction (Motorcycle Safety Foundation). And be legible — NHTSA advises riding defensively, staying alert with eyes and ears, and communicating with eye contact and signals (NHTSA, Bicycle Safety). Predictability removes the surprise that causes collisions.

The scooter’s own penalty

One honest caveat: a scooter is harder to control in an emergency than a bike. Research notes e-scooter riders face reduced braking and steering capacity, more instability from surface vibration and speed changes, and an upright posture that hampers balance, signalling and scanning (PMC 2025). That argues for lower speeds and more space at junctions, not less. Finally, make yourself unmissable with movement: reflective markings on your moving ankles and knees (“biomotion”) lift recognition distance up to six-fold — and our visibility guide explains in detail why riders consistently overestimate how visible they already are (QUT Vision Function Group). Ride as if you’re invisible, position so you’re not, and treat every junction as the moment that matters. More gear and rules in our safety-gear and traffic guide.
