Drivers of four-wheeled motor vehicles are obliged to carry a suitable warning sign (warning triangle) und reflective warning clothing at all times. No such obligation exists for two-wheeled vehicles.
These must be kept inside the vehicle and, when necessary (e.g. in case of an accident or a breakdown), worn when getting out of the vehicle. Appropriate warning clothes are, for example, jackets, overalls, trousers and blankets, which correspond to Austrian Standard (ÖNORM) EN 471 or ÖNORM EN ISO 20471.
