Inspection Types & Safety Components Check
The type of inspection your vehicle gets depends on its age and the type of fuel it runs on. Brand new cars are exempt from State Inspection for the first 2 years. Cars that run on gasoline and are 2 to 24 years old are subject to both safety and emissions tests. Motorcycles, diesel engine, fully electric and vehicles older than 24 years only require a safety inspection.
Emissions Test or Smog Check
In Texas, gasoline powered cars and trucks built in 1996 or earlier are subject to the Accelerated Simulation Mode (ASM) test. If the vehicle was built after 1996 it will undergo the On-Board Diagnostic (OBDII) testing.
The vehicle gets put through the paces on a dynamometer while a probe placed in the tailpipe reads the levels of carbon dioxide (CO2) and other gasses emitted from the car’s exhaust.
The vehicle gets a full scan of it’s on-board diagnostics system to determine whether the car emission control readings fall within acceptable standards.
Note: We only perform emission inspections on vehicles built in 1996 and newer. We can unfortunately not assist you if your car requires ASM testing since we do not have the required dynamometer.
Vehicle Safety Inspection Components
The safety inspection is the same for all vehicles regardless of age, fuel type it runs on and regardless whether it requires only a safety test or a combination of safety and emission tests.
Some of the basic safety components that get checked on your car include, but not limited to:
- All Exterior Light Bulbs and Controls
- Brakes and Parking Brake
- Exhaust Emission System
- Exhaust System
- Gas cap
- Head Light Assembly
- Seat Belts
- Tail Light Assembly
- Vehicle Identification Number (VIN)
- Wheel Assembly
- Window Tint
- Windshield Wipers
