State Car & Truck Inspection & Emissions Testing

With normal vehicle inspections and regular emissions checks, drivers can be informed about any issues with their vehicles. In case your vehicle didn’t clear the inspection or the vehicle-emissions test, you will know it needs some immediate attention and possibly some repair work. Car owners must schedule the repair work as soon as possible because it may jeopardize the dependability of the car and even cause hefty fines or even an invalidated registration. For that reason, it is highly advised to have your car checked by a competent professional at the very least every 6 months to avoid all these inconveniences. Some commonly asked inquiries on car inspection are outlined below.


What is On-Board Diagnostics or OBD?

The OBD or On-Board Diagnostics, or OBD II is a standard computer system implemented in all vehicles created in and after 1996. Simply put, all the vehicles made in 1996 and after will have an OBD system in them, which provides information reports on self-diagnosis of the car commonly utilized by automotive service technicians prior to performing any automobile repair work.


Common Causes of a Failed Emissions Test

A car emissions test can fail for lots of factors as a result of malfunctioning car elements such as an injector, oxygen sensing unit, ignition system or even an EVAP system. One of the most common reasons is faulty injectors. Either the injectors or a malfunctioning oxygen sensing unit can set off a “abundant air-fuel mix” causing an unsatisfactory emissions test result.

If your vehicle has a damaged ignition system, there is a higher possibility that it may be the cause of a rise in exhaust discharges. This, consequently, can lead to a failed vehicle-emissions test.

Any kind of issue or shortages in the EVAP system or evaporative emission control system can trigger a problem in the handling of the gasoline vapor discharged from the car causing air pollution.

If your vehicle hasn’t undergone regular maintenance and the “check engine” light is illuminated on the dashboard, your vehicle might not clear the emissions test.


What Do They Check for in a Vehicle Inspection?

An accredited examiner performs a vehicle examination at state-approved inspection stations only. This is what they will look for:

  • Headlights: front lights inspection to ensure appropriate operation, no cracked lenses or lamps, lights are the proper 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 check tire problems for any kind of indications of deterioration and if there is a need for replacement
  • Mirrors: Check to make sure no mirrors are cracked, damaged or missing
  • Safety belt: to examine safety belt condition and make sure they are safely working or need replacing
  • Brakes: a thorough brake assessment to ensure proper brake response and if there are any type of brake fluid leakages
  • Horn: ensure the horn is working correctly
  • Inspection of suspension and shock absorbers

How Long Does A Safety Inspection Take?

Depending on the state, city, and area where the vehicle tests are performed, the car safety inspection period might differ. However, for a majority of cars, this process generally takes an hour to 90 minutes.
