State Vehicle Emissions Testing & Inspection

With normal vehicle inspections and routine emissions checks, vehicle drivers can be familiarized with any mechanical problems with their cars. In case your car didn’t clear the inspection or the emissions test, you will know it needs some prompt attention and probably some repair. Vehicle owners should make plans for the repair or service as soon as possible because it may jeopardize the dependability of the automobile and also cause substantial fines or even a disqualified registration. Therefore, it is highly advised to have your car examined by a qualified professional at least 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 vehicles built in and after 1996. Basically, all the cars made in 1996 and after will have an OBD system in them, which provides data reports on self-diagnosis of the car usually used by automotive technicians before executing any type of vehicle repair work.

Common Causes of a Failed Emissions Test

An emissions examination can fail for numerous reasons due to malfunctioning car elements such as an injector, oxygen sensing unit, ignition system and even an EVAP system. One of the most common reasons is faulty injectors. Either the injectors or a malfunctioning oxygen sensing unit can trigger a “rich air-fuel mixture” causing an unsatisfactory vehicle emissions test.

If your automobile has damaged spark plugs, there is a greater possibility that it might be the reason for a rise in exhaust emissions. This, consequently, can lead to a failed vehicle-emissions test.

Any kind of issue or deficiencies in the EVAP system or evaporative exhaust control system can cause trouble in the handling of the gas vapor emitted from the vehicle causing atmospheric pollution.

If your automobile hasn’t undertaken routine maintenance and the “check engine” light is brightened on the dashboard, your automobile might fail the vehicle-emissions test.

What Do They Check for in a Vehicle Inspection?

An accredited inspector performs a vehicle inspection at state-approved assessment stations only. This is what they will check for:

  • Front lights: headlight inspection to make sure of proper operation, no broken lenses or lights, lights are the right 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 problems for any type of signs of damage and if there is a need for replacement
  • Mirrors: Ensure no mirrors are cracked, damaged or missing
  • Seat belts: to analyze seat belts’ condition and make sure they are safely working or require replacing
  • Brakes: a detailed brake evaluation to ensure proper brake action and if there is any brake fluid leakages
  • Horn: make sure the horn is working correctly
  • Inspection of suspension and shock absorbers

How Long Does A Safety Inspection Take?

Depending upon the state, city, and area where the vehicle examinations are carried out, the car safety inspection duration might vary. However, for most cars, this process typically takes an hour to 90 minutes.
