As per the usual procedure, motorised vehicles are assigned a registration number issued by the RTO of the respective district and the state they belong to. As per Central Motor Vehicle Rules (CMVR), the assigned registration numbers are then displayed on the rear and front ends of the vehicles.
But, the vehicles that are registered under the Ministry of Defence are given a different kind of number plates. If you study those number plates closely, you will notice that they contain an upward pointing arrow which is generally first or the third character followed by the last two digits of the year in which the vehicle is manufactured or imported. It is followed by a base code and the serial number/vehicle number.
Here is the exact breakdown of the characters and numbers that a number plate of a military vehicle contains:
1. The upward arrow indicates defence property.
2. The year of the model.
3. The class of the vehicle.
4. The vehicle number.
The number plates of the military vehicles are mostly of black and green colour. These vehicles are used for the official purchase only.
