The 1968 Vienna Convention (administered by UN Working Party 1 on road traffic safety) covers road traffic safety regulations and as such establishes principles to govern traffic laws. One of the fundamental prinicples of the Convention has been the concept that a driver is always fully in control and responsible for the behavior of a vehicle in traffic. With the advent of automatic systems to direct the behavior of various vehicle systems such as lighting, but increasingly towards collision avoidance, this basic principle is no longer completely in concert with advanced vehicle technologies. Consequently, WP.29 has engaged in discussions with WP.1 to address inconsistencies between the Convention and WP.29 regulations.
