State Car & Truck Inspection & Emissions Testing

With regular car inspections and regular emissions checks, vehicle drivers can be made aware of any issues with their vehicles. In case your vehicle failed to pass the inspection or the emissions test, you will definitely know it needs some prompt attention and potentially some repair or service. Car owners should proceed with the repair or service ASAP because it might endanger the reliability of the vehicle and even cause hefty fines or perhaps an invalidated registration. For that reason, it is always recommended to have your car examined by a competent service technician a minimum of every 6 months to avoid all these problems. Some commonly asked inquiries on automobile inspection are described below.

What is On-Board Diagnostics or OBD?

The OBD or On-Board Diagnostics, or OBD II is a standardized computer system implemented in all automobiles created in and after 1996. Simply put, 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 utilized by automotive specialists before doing any vehicle repair work.

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

A car emissions test can fail for many factors because of malfunctioning car components such as an injector, oxygen sensing unit, spark plugs and even an EVAP system. The most common reasons is faulty injectors. Either the injectors or a malfunctioning oxygen sensor can set off a “abundant air-fuel mixture” leading to a poor vehicle emissions test.

If your car has damaged spark plugs, there is a higher possibility that it may be the cause of an increase in exhaust discharges. This, subsequently, can lead to a failed vehicle-emissions test.

Any kind of trouble or deficiencies in the EVAP system or evaporative exhaust control system can trigger a problem in the handling of the gasoline vapor released from the car leading to atmospheric pollution.

If your car hasn’t undertaken routine maintenance and the “check engine” light is illuminated on the control panel, your automobile might not pass the vehicle-emissions test.

What Do They Check for in a Car Inspection?

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

  • Front lights: front lights inspection to ensure correct operation, no broken lenses or lamps, lights are the correct shade, 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 broken taillights
  • Wheels and Tires: to check tire conditions for any kind of indicators of damage and if there is a need for replacement
  • Mirrors: Make sure no mirrors are broken, damaged or missing
  • Safety belt: to examine safety belt condition and ensure they are safely working or require replacing
  • Brakes: a thorough brake examination to ensure proper brake action and if there are any kind of brake fluid leakages
  • Horn: make sure the horn is operative
  • Assessment of suspension and shock absorbers

How Long Does It Take To Get A Safety Inspection?

Depending upon the state, city, and area where the car examinations are carried out, the automobile safety inspection duration may differ. Nonetheless, for most vehicles, this process generally takes an hour to an hour and a half.
