State Car Emissions Testing & Inspection

With regular car inspections and routine emissions checks, vehicle drivers can be made aware of any issues with their vehicles. In case your vehicle fails the inspection or the vehicle-emissions test, you will know it needs some prompt attention and probably some repair or service. Vehicle owners need to make plans for the repair as soon as possible because it might endanger the dependability of the car and also result in hefty fines and even a disqualified registration. For that reason, it is always recommended to have your vehicle checked by an experienced technician a minimum of every six months to avoid all these troubles. Some commonly asked questions on car inspection are outlined here.


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 constructed in and after 1996. Simply put, all the vehicles made in 1996 and after will have an OBD system in them, which supplies information reports on self-diagnosis of the vehicle often used by automotive service technicians prior to doing any automobile repair work.


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

A car emissions test can fail for numerous reasons as a result of malfunctioning car parts such as an injector, oxygen sensing unit, spark plugs or perhaps an EVAP system. One of the most common causes is faulty injectors. Either the injectors or a malfunctioning oxygen sensing unit can trigger a “rich air-fuel mix” resulting in a poor vehicle emissions test.

If your car has a damaged ignition system, there is a greater possibility that it might be the cause of a rise in exhaust discharges. This, subsequently, can cause a failed vehicle-emissions test.

Any type of trouble or deficiencies in the EVAP system or evaporative emission control system can trigger a trouble in the handling of the gasoline vapor released from the vehicle causing air pollution.

If your car hasn’t gone through regular maintenance and the “check engine” light is lit up on the control panel, your car may not pass the emissions test.


What Do They Check for in a Vehicle Inspection?

An authorized assessor conducts a car examination at state-approved assessment stations only. This is what they will look for:

  • Headlights: headlight inspection to make sure of correct operation, no cracked lenses or lamps, lights are the correct 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 broken taillights
  • Wheels and Tires: to check tire conditions for any type of indications of deterioration and if there is a need for replacement
  • Mirrors: Make sure no mirrors are cracked, damaged or missing
  • Safety belt: to assess seat belts’ condition and ensure they are securely operating or need a replacement
  • Brakes: a thorough brake evaluation to ensure proper brake reaction and if there is any brake fluid leakages
  • Horn: ensure the horn is working correctly
  • Evaluation of suspension and shock absorbers

How Long Does A Safety Inspection Take?

Depending on the state, city, and area where the car examinations are performed, the automobile safety inspection period might vary. Nonetheless, for a majority of vehicles, this procedure typically takes an hour to an hour and a half.
