What does the sign on the vehicle indicate?

All drivers of automobiles who obtain a driving license for the first time, in this case for a passenger car, must display the V-13 signal on the rear left part of the vehicle, which consists of a rectangular plate measuring 19.5 x 15 centimeters with a green background and a white letter "L". This plate will help other road users to know that the driver of this vehicle is a novice driver.
