1. Scope and purpose
1.1 This Regulation applies to external projections of category M1 vehicles.[1] It does not apply to exterior devices for indirect vision or to the ball of towing devices.
1.2 The purpose of this Regulation is to reduce the risk or seriousness of bodily injury to a person hit by the bodywork or brushing against it in the event of a collision. This is valid both when the vehicle is stationary and in motion.
2. Definitions
For the purposes of this Regulation:
2.1.  "Approval of a vehicle" means the approval of a vehicle type with regard to its external projections;
2.2.  "Vehicle type" means a category of motor vehicles which do not differ in such essential respects as, shape or materials of the external surface;
2.3.  "External surface" means the outside of the vehicle including the bonnet, the lid of the luggage compartment, the doors, the wings, the roof, the lighting and light-signalling devices and the visible strengthening components.
2.4  "Floor line" means the line determined as follows:
Successively position round a laden vehicle a cone with a vertical axis the height of which is not defined, and with a half angle of 30 in such a way that it contacts, constantly and as low as possible, the external surface of the vehicle.  The floor line is the geometric trace of these points of contact.  In determining the floor line, the jacking points, exhaust pipes or wheels shall not be taken into consideration.  The gaps of the wheel arches are assumed to be filled in by an imaginary surface forming a smooth continuation of the surrounding external surface.  At both ends of the vehicle the bumper shall be taken into consideration when establishing the floor line.  Dependent upon the particular vehicle the floor line trace may occur at the bumper section extremity or at the body panel below the bumper.  Where two or more points of contact occur simultaneously, the lower point of contact shall be used to determine the floor line;
2.5.  "Radius of curvature" means the radius of the arc of a circle which comes closest to the rounded form of the component
