Vehicle modifications and registration class
Modifications to a vehicle can affect its registration
Part 106 of the DMV Regulations describes the vehicles that are registered in the commercial class and in the passenger class. Part 106 also describes how some modifications that you make to your vehicle can affect the correct registration class of your vehicle. A description of the modifications appears below. Each description includes a reference to the DMV Regulations.
Important: The DMV cannot examine your vehicle to determine the correct registration class. You must determine the correct registration class for your vehicle.
Modifications that change a registration from 'Passenger' class to 'Commercial' class
Cars (Part 106.2 (e)) - you can register your car in the 'Commercial' class if all the seats behind the driver are removed. Instead of the seats, you must install a permanent box or permanent rack to carry cargo.
Station Wagons and Vans (Part 106.2 (f)) - you can register your station wagon or your van in the commercial class if all the seats and all the seat fittings behind the driver are removed completely.
Modifications that change a registration from 'Commercial' class to 'Passenger' class
Vans (Part 106.3 (d)) - you can register a van in the 'Passenger' class if the van has
- at least one side window behind the driver
- at least one seat or set of seat fittings that is installed behind the driver
- camping equipment that is installed behind the driver.
- 'camping equipment' indicates that you have a permanent bed, a permanent stove, or a permanent refrigerator in the vehicle
- if this equipment is removed and you use the van, you must register the van as a commercial vehicle
Pick-up Trucks (Part 106.6 (b) and (c)) - you may register a pick-up truck in the passenger class if it meets certain conditions, depending on its unladen weight.
If you have a modified or unmodified pick-up truck with an unladen weight less than 5,501 lbs., then you may register it in the passenger class if it meets the following conditions:
- the pick-up truck does not have any business advertisements
- the pick-up is used exclusively for non-commercial purposes
If you have a modified pick-up truck with an unladen weight greater than 5,500 lbs., then you may register it in the passenger class if it meets the following conditions:
- the pick-up truck does not have any business advertisements and is used exclusively for non-commercial purposes
- a camper top having one or more side windows completely encloses the truck bed
- the pick-up truck has seats, seat fittings, or camping equipment installed in the truck bed
- 'camping equipment' indicates that you have a bed, a stove, or a refrigerator in the vehicle
NOTE: These modifications must be permanent. If you use the pick-up truck without the required modifications, then you must register it in the commercial registration class.
