1. Method for classifying vehicles with reference to their vehicle length comprising directing a radar beam in the form of a radar cone toward a roadway, said beam having a beam spread angle horizontally oriented at an acute positioning angle at a distance to the roadway and through evaluation of the radar signals generated by reflection on a vehicle traveling on the roadway, a driven distance over which the vehicle reflects the radar beam while traveling, determining from the signals, a range value by means of which a passage distance is determined, over which the vehicle travels through the radar cone and determining the vehicle length by comparing said length with vehicle lengths that are typical for individual vehicle classes, from the difference between the driven distance and the passage distance, in order to classify the vehicle.
