Antiques & Classic Registered Vehicles
Vehicles registered as "Antiques" are exempted from the annual inspection. To see the restrictions on the use of antiques or to obtain more information on how to register your vehicle as an "Antique", see the TxDOT website.
Vehicles registered as "Classic" are required to have the annual safety inspection. These types of vehicles are inspected like any passenger vehicle. Certain items of inspection, however, may or may not be required to be inspected, depending on the age of the car. (For example, seatbelts and anchorages are only required if the vehicle was originally manufactured with them.)
Trailers, semitrailers, mobile homes, motor homes, and vehicles which are too large for standardized inspection bays need not be inspected within the inspection building. However, these types of vehicles must be inspected near the inspection building in a space approved by the supervising Department representative.
Motorhomes in EMISSIONS counties are also required to have the appropriate emissions test performed.
If the motorhome is 1996 or newer and OBDII capable, then your motorhome will receive an OBDII test. Not all motorhomes in this age category come equipped with OBDII compliant plugins; therefore, if your motorhome or RV is not OBDII ready, it will require the ASM test.
If the motorhome is 1995 or older it requires the ASM emissions test. The ASM equipment has an 8500 pound limitation. Therefore, if your motorhome exceeds this weight limitation, it will be switched to the TSI testing mode (no dyno).
Whether having the ASM or OBDII test performed, you should try to find an inspection station where the equipment is close to the bay opening. The analyzers come with a 20 foot lead; however, where the analyzer is housed will determine whether or not a station can roll their machinery outside the bay to conduct this type of inspection. It is recommended that you make contact with the station prior to arrival to ensure their equipment can accommodate your vehicle.
