154. High-visibility clothing
High-visibility clothing is clothing designed to make a person easier for other road users to see. It commonly uses bright fluorescent material combined with retro-reflective strips that reflect light from vehicle headlights.
High-visibility clothing is especially useful when a driver or passenger must leave a vehicle after a breakdown or emergency. Requirements vary between countries, so drivers should check whether a reflective safety vest must be carried or worn.

Is reflective clothing a compulsory carried item in every British car?
The Highway Code recommends reflective or fluorescent clothing during a breakdown and says to put on high-visibility clothing if it is readily available. This is different from a national rule requiring an ordinary private car to carry a reflective vest.
