 Vehicles registered in Israel often use 'disguised' plates, either remade black on white without the blue band, or with the blue band covered, when travelling outside of the country.Police registration plates are rectangular with red background and embossed with white registration number.Police registration numbers consist of the letter Mem (מ), representing the word ""Mishtara"" (police) and the number, which is issued according to the seniority of the car holder.
