State Car & Truck Emissions Testing & Inspection

With normal car inspections and regular emissions checks, drivers can be familiarized with any mechanical problems with their cars. In case your vehicle failed to pass the inspection or the vehicle-emissions test, you will know it needs some immediate attention and probably some repair or service. Vehicle owners must proceed with the repair or service ASAP because it may jeopardize the reliability of the car and also result in substantial penalties and even a disqualified registration. Therefore, it is always advised to have your car inspected by a skilled specialist a minimum of every 6 months to avoid all these hassles. Some frequently asked inquiries on car inspection are described below.

What is On-Board Diagnostics or OBD?

The OBD or On-Board Diagnostics, or OBD II is a standard computer system applied in all automobiles created in and after 1996. In short, all the automobiles made in 1996 and after will have an OBD system in them, which supplies data reports on self-diagnosis of the car frequently used by automotive service technicians before performing any kind of automobile repairs.

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

An emissions test can fail for many reasons because of malfunctioning automobile components such as an injector, oxygen sensor, spark plugs and even an EVAP system. One of the most typical reasons is malfunctioning injectors. Either the injectors or a malfunctioning oxygen sensing unit can trigger a “rich air-fuel mixture” causing a poor vehicle emissions test result.

If your car has a damaged ignition system, there is a higher possibility that it might be the cause of a boost in exhaust emissions. This, consequently, can lead to a failed vehicle-emissions examination.

Any trouble or deficiencies in the EVAP system or evaporative exhaust control system can trigger an issue in the handling of the gasoline vapor discharged from the automobile leading to atmospheric pollution.

If your car hasn’t undertaken routine maintenance and the “check engine” light is illuminated on the dashboard, your vehicle may not clear the vehicle-emissions test.

What Do They Check for in a Vehicle Inspection?

An authorized assessor carries out an automobile inspection at state-approved inspection stations only. This is what they will look for:

  • Headlights: headlight evaluation to make sure of proper operation, no broken lenses or lamps, lights are the right color, 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 damaged taillights
  • Wheels and Tires: to inspect tire conditions for any indicators of damage and if there is a requirement for replacement
  • Mirrors: Ensure no mirrors are broken, broken or missing
  • Safety belt: to analyze seat belts’ condition and ensure they are securely working or need a replacement
  • Brakes: an in-depth brake inspection to ensure proper brake reaction and if there is any brake fluid leaks
  • Horn: make sure the horn is working correctly
  • Assessment of suspension and shock absorbers

How Long Does It Take To Get A Safety Inspection?

Based on the state, city, and region where the car tests are conducted, the vehicle safety inspection duration might vary. However, for a majority of cars, this procedure usually takes one hour to an hour and a half.
