Commercial Vehicle Registration

You may need to register your vehicle as commercial if certain conditions apply.

Light Duty Vehicles

Passenger cars, ¾ ton or less pickup trucks and ¾ ton or less vans, used for commercial purposes 1,000 or more hours in a vehicle registration year, must be registered commercially. 

A vehicle registered in the name of a commercial enterprise must be registered commercially unless the registering applicant certifies that the vehicle will not be maintained and used for commercial purposes.

For the registration of 1-ton pickup trucks used for either commercial or personal use, the applicant must declare a gross weight and pay gross weight fees and a $4.00 commercial fee.

What is a declared gross weight?

Gross weight is the sum of the empty weight in pounds of a motor vehicle combination (power unit and trailer) plus the weight in pounds of the load to be carried on the motor vehicle combination at any point in time.  Customers declare the maximum gross weight at which they will operate their vehicle and then pay the corresponding fee as determined by the following table.
