As a general rule, high-visibility clothing should be worn when a person’s visibility needs to be increased. The main aim is to distinguish the wearer as clearly as possible from their surroundings, so that they are visible from all angles and in all weather conditions. This applies particularly in work situations where the risk of being overlooked exists both day and night. Typical areas where high-visibility clothing is used include: road construction, municipal services, haulage companies, refuse collection, airport runways and rail transport.
