Are there any proposals for making it compulsory for cyclists to wear reflective clothing (high visibility) or similar when riding their bike?

No, there are no proposals to change the law in Great Britain to require pedal cyclists to wear high visibility clothing.

Of course, it is important that cyclists ensure they can be seen easily, as this reduces the risk of cyclists being involved in accidents. RoSPA advises cyclists to wear brightly-coloured or fluorescent clothing in daylight and reflective clothing or accessories in the dark.

Cyclists must, by law, have front and rear lights lit and reflectors on their bicycles in the dark. Good conspicuity is important in both daylight and the dark. Around 80 per cent of cyclist casualties occur in daylight, but collisions in the dark are more likely to be fatal for the cyclist. "Cyclists wearing dark clothing at night" is a factor in about 10 per cent of fatal cycling accidents.

Most importantly of all, RoSPA urges drivers and motorcyclists to ensure they keep a proper look-out for vulnerable road users, not least because "look but failed to see" is the most frequently-reported factor in accidents on Britain’s roads. Drivers and motorcyclists also need to watch their speed, particularly in residential areas and near schools.
