In order to renew tags for your car, your vehicle must pass a yearly emissions test if:
It is a gasoline-powered vehicle 1975 or newer with a gross vehicle
weight of 10,500 pounds or less. (Weight information is
located on the vehicle's door jam.)
It is a diesel-powered vehicle 1975 or newer with a gross vehicle
weight of 10,500 pounds or less.
Vehicles from model year 1974 and before, electric cars, motorcycles, and antique cars are exempt from testing.
