State Vehicle Inspection & Emissions Testing

With regular automobile inspections and routine emissions checks, drivers can be made aware of any mechanical issues with their vehicles. In case your vehicle failed to pass the inspection or the emissions test, you will know it needs some immediate attention and probably some repair. Vehicle owners must make plans for the repair or service as soon as possible because it may jeopardize the reliability of the car and also result in substantial fines or perhaps an invalidated registration. Therefore, it is highly recommended to have your car checked by an experienced professional a minimum of every 6 months to avoid all these inconveniences. Some frequently asked questions on automobile inspection are outlined below.

What is On-Board Diagnostics?

The OBD or On-Board Diagnostics, or OBD II is a standard computer system carried out in all vehicles constructed in and after 1996. In short, all the cars made in 1996 and after will have an OBD system in them, which offers information reports on self-diagnosis of the car frequently used by automotive technicians before carrying out any kind of automobile repairs.

What Are The Most Common Causes Of a Failed Emissions Test?

A car emissions examination can fail for many reasons as a result of malfunctioning car components such as an injector, oxygen sensor, ignition system or even an EVAP system. The most common reason is defective injectors. Either the injectors or a malfunctioning oxygen sensor can set off a “abundant air-fuel combination” resulting in a poor vehicle emissions test result.

If your car has a worn-out ignition system, there is a greater possibility that it might be the source of a boost in exhaust emissions. This, subsequently, can result in a failed vehicle-emissions examination.

Any issue or deficiencies in the EVAP system or evaporative exhaust control system can trigger a trouble in the handling of the gas vapor emitted from the vehicle resulting in atmospheric pollution.

If your automobile hasn’t undertaken regular maintenance and the “check engine” light is lit up on the control panel, your vehicle might fail the vehicle-emissions test.

What Do They Check for in a Car Inspection?

A licensed inspector carries out an automobile inspection at state-approved evaluation stations only. This is what they will check for:

  • Headlights: headlight check to ensure appropriate operation, no broken lenses or lamps, lights are the correct shade, are identical, and turn signals are operable.
  • Tail lights: Turn signals, marker lights, hazard lights, license plate lights, brake lights, reverse lights are operable, and no broken taillights
  • Wheels and Tires: to check tire conditions for any indications of deterioration and if there is a need for replacement
  • Mirrors: Ensure no mirrors are broken, broken or missing
  • Safety belt: to analyze safety belt condition and ensure they are securely working or require replacing
  • Brakes: a thorough brake assessment to ensure proper brake response and if there is any brake fluid leakages
  • Horn: ensure the horn is operative
  • Assessment of suspension and shock absorbers

How Long Does It Take To Get A Safety Inspection?

Depending on the state, city, and region where the vehicle examinations are performed, the car safety inspection duration might vary. However, for a majority of cars, this procedure usually takes one hour to 90 minutes.
