An assessment has been made of the effect on accidents of the change in regulations governing the lighting of parked vehicles at night, which since April 1972 have allowed some classes of vehicles to park without lights on roads with speed limits of 30 mile/h or less. The main conclusion was that the change in regulations was followed by an increase in parked vehicle involvements for cars, light goods vehicles, and two wheeled vehicles amounting to 36%. This represents 1100 extra parked vehicles involvements in injury accidents in the first year.
