Texas Vehicle Inspection FAQ

 


State Vehicle Emissions Testing & Inspection

With regular automobile inspections and regular emissions checks, drivers can be made aware of any issues with their vehicles. In case your vehicle fails the inspection or the vehicle-emissions test, you will know it requires some immediate attention and potentially some repair. Car owners should make plans for the repair ASAP because it may jeopardize the reliability of the car and even lead to significant penalties or even an invalidated registration. For that reason, it is always advised to have your vehicle checked by a qualified technician at least every six months to avoid all these hassles. Some commonly asked questions on vehicle inspection are described below.


What is On-Board Diagnostics?

The OBD or On-Board Diagnostics, or OBD II is a standardized computer system executed in all automobiles constructed in and after 1996. In other words, all the automobiles made in 1996 and after will certainly have an OBD system in them, which supplies data reports on self-diagnosis of the vehicle frequently used by automotive technicians prior to doing any vehicle repairs.


Common Causes of a Failed Emissions Test

A car emissions test can fail for many reasons due to malfunctioning car components such as an injector, oxygen sensing unit, spark plugs or perhaps an EVAP system. The most typical causes is damaged injectors. Either the injectors or a malfunctioning oxygen sensing unit can set off a “abundant air-fuel mix” bring about an unsatisfactory vehicle emissions test.

If your automobile has damaged ignition system, there is a higher chance that it might be the root cause of a rise in exhaust discharges. This, consequently, can cause a failed vehicle-emissions test.

Any type of trouble or shortages in the EVAP system or evaporative emission control system can cause a trouble in the handling of the gas vapor discharged from the automobile resulting in atmospheric pollution.

If your car hasn’t undertaken regular maintenance and the “check engine” light is brightened on the control panel, your automobile may not clear the vehicle-emissions test.


What Do They Check for in a Vehicle Inspection?

An authorized inspector conducts a car inspection at state-approved inspection stations only. This is what they will look for:

  • Front lights: headlamps evaluation to ensure proper operation, no cracked lenses or lights, lights are the correct color, are the same, and turn signals are operable.
  • Tail lights: Turn signals, marker lights, hazard lights, license plate lights, brake lights, reverse lights are operable, and no damaged taillights
  • Wheels and Tires: to inspect tire conditions for any indicators of damage and if there is a need for replacement
  • Mirrors: Check to make sure no mirrors are cracked, broken or missing
  • Safety belt: to examine safety belt condition and make sure they are securely working or need a replacement
  • Brakes: a thorough brake assessment to ensure proper brake reaction and if there is any brake fluid leaks
  • Horn: ensure the horn is working correctly
  • Inspection of suspension and shock absorbers

How Long Does A Safety Inspection Take?

Based on the state, city, and region where the car tests are carried out, the car safety inspection period may differ. However, for most cars, this procedure usually takes an hour to an hour and a half.
