State Vehicle Emissions Testing & Inspection

With normal vehicle inspections and regular emissions checks, vehicle drivers can be informed about any mechanical issues with their cars. In case your car fails the inspection or the emissions test, you will know it requires some immediate attention and potentially some repair work. Vehicle owners must make plans for the repair ASAP because it might endanger the reliability of the vehicle and even lead to significant penalties or even a disqualified registration. For that reason, it is always recommended to have your vehicle inspected by a competent professional a minimum of every six months to avoid all these inconveniences. Some frequently asked questions on car inspection are described here.


What is On-Board Diagnostics?

The OBD or On-Board Diagnostics, or OBD II is a standard computer system implemented in all cars created in and after 1996. Basically, all the automobiles made in 1996 and after will have an OBD system in them, which offers information reports on self-diagnosis of the vehicle usually utilized by automotive service technicians before carrying out any type of automobile repair work.


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

A car emissions test can fail for lots of reasons because of malfunctioning vehicle components such as an injector, oxygen sensor, spark plugs and even an EVAP system. One of the more common reasons is damaged injectors. Either the injectors or a malfunctioning oxygen sensor can trigger a “abundant air-fuel mixture” leading to an unsatisfactory vehicle emissions test result.

If your vehicle has damaged spark plugs, there is a greater chance that it may be the reason for a rise in exhaust discharges. This, in turn, can cause a failed emissions examination.

Any trouble or shortages in the EVAP system or evaporative emission control system can cause a trouble in the handling of the gasoline vapor discharged from the car resulting in atmospheric pollution.

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


What Do They Check for in a Vehicle Inspection?

An authorized examiner conducts an automobile assessment at state-approved evaluation stations only. This is what they will look for:

  • Headlights: front lights check to ensure correct operation, no broken lenses or lamps, lights are the proper 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 damaged taillights
  • Wheels and Tires: to examine tire problems for any type of signs of wear and tear and if there is a requirement for replacement
  • Mirrors: Check to make sure no mirrors are broken, broken or missing
  • Safety belt: to analyze seat belts’ condition and make sure they are securely working or require a replacement
  • Brakes: an in-depth brake examination to ensure proper brake action and if there are any kind of brake fluid leakages
  • Horn: ensure the horn is working correctly
  • Examination of suspension and shock absorbers

How Long Does It Take To Get A Safety Inspection?

Based on the state, city, and area where the car examinations are carried out, the vehicle safety inspection duration might differ. Nevertheless, for a majority of vehicles, this process usually takes an hour to 90 minutes.
