High-visibility clothing

Conspicuous behaviors, such as the wearing of high-visibility clothing, the use of headlights in the daytime, and the use of a white helmet, reduced the risk of a rider facing a collision.

[6] A Cochrane Systematic Review of research evidence for the effectiveness of visibility aids (fluorescent and retroreflective clothing and equipment) was carried out by Kwan and Mapstone in 2006.

[7] The authors found 42 studies which collectively suggested that fluorescent clothing could increase the distance at which drivers could detect and then recognise cyclists in daylight conditions.

At that time there were no studies published that had actually demonstrated a reduction in collision crashes for bicyclists wearing fluorescent or retroreflective clothing whilst on public roads.

[8] A 2012 British case-control study showed a non-significant increase in the odds of a crash for users of reflective conspicuity aids whilst cycling.

[11] Since April 2013, New York City regulations require commercial cyclists, such as restaurant delivery persons or bike messengers, to wear high visibility clothing while riding.

[13] Fluorescent orange jackets, known as "fire-flies", were issued to track workers on the Pollokshields to Eglinton Street electrified section in Glasgow;[14] they were later tried in other areas, such as Edinburgh, Aberdeen and Inverness.

[13] Following trials, high-visibility clothing was issued to engineering and other staff working on the electrified lines of the London Midland Region of British Railways in 1965.

It was thought to be more important due to the higher speeds of the newly electrified West Coast Main Line route from London Euston to Birmingham, Manchester and Liverpool.

It also includes many optional features, such as a 5-point breakaway design for easy removal, panels readily identifying the wearer as an emergency responder, and radio and badge holders.

[24] Hunting laws in each state or province may require hunters to wear designated garments in blaze orange to prevent misidentification of humans as game animals, and resulting shooting accidents.
