A study by University of Bath psychological scientist Ian Walker finds that high-visibility clothing is unlikely to prevent the most dangerous passing behavior from drivers. Around 1–2% of overtakes were within 50 cm (about 18 inches) of the rider regardless of what he wore, implying a small proportion of motorists’ passes will always be dangerously close regardless of what a bicyclist wears.
“Many people have theories to say that cyclists can make themselves safer if they wear this or that. Our study suggests that, no matter what you wear, it will do nothing to prevent a small minority of people from getting dangerously close when they overtake you,” says Walker.
A past study from Walker demonstrated that drivers actually encroached much closer to cyclists wearing helmets than those without one. Drivers perceived helmeted riders as more experienced, and thus assumed they could get closer to them as they passed. The research team wanted to investigate whether a bicyclist’s outfit would influence perceptions of experience, and hence, how close drivers got while passing.
A member of the research team, Ian Garrard from Brunel University, used an ultrasonic distance sensor to record how close each vehicle passed during his daily bike commute between Berkshire and outer London (about 50 km round trip). Over several months, data were collected from 5,690 passing vehicles.
Seven outfits were tested, ranging from a specialized racing cyclist outfit—implying high experience and skill—to a vest with “novice cyclist” printed on the back, clearly communicating low experience.
Some outfits included a high-visibility bicycling jacket or high-visibility safety vests. One vest prominently displayed the word ‘police’ along with a warning that the rider was video-recording their journey. For comparison, another high-visibility vest was modeled after a police officer’s jacket but with one change—it read “polite” instead of “police.”
