State Vehicle Inspection & Emissions Testing

With routine vehicle inspections and periodic emissions checks, drivers can be informed about any mechanical problems with their cars. In case your vehicle fails the inspection or the vehicle-emissions test, you will definitely know it is ready for some prompt attention and possibly some repair. Vehicle owners need to make plans for the repair work as soon as possible because it may jeopardize the dependability of the car and even result in hefty fines and even an invalidated registration. Therefore, it is always recommended to have your vehicle inspected by an experienced specialist at the very least every six months to avoid all these problems. Some frequently asked questions on automobile inspection are described here.


What is On-Board Diagnostics?

The OBD or On-Board Diagnostics, or OBD II is a standard computer system applied in all vehicles built in and after 1996. In short, all the vehicles made in 1996 and after will certainly have an OBD system in them, which offers information records on self-diagnosis of the car often utilized by automobile technicians before performing any type of automobile repairs.


Common Causes of a Failed Emissions Test

A car emissions examination can fail for many reasons as a result of malfunctioning automobile components such as an injector, oxygen sensor, ignition system or even an EVAP system. The most common reasons is damaged injectors. Either the injectors or a malfunctioning oxygen sensing unit can set off a “rich air-fuel mix” bring about an unsatisfactory vehicle emissions test.

If your vehicle has damaged ignition system, there is a greater possibility that it might be the root cause of a boost in exhaust emissions. This, in turn, can cause a failed emissions examination.

Any type of problem or shortages in the EVAP system or evaporative emission control system can trigger a trouble in the handling of the gas vapor released from the automobile resulting in atmospheric pollution.

If your car hasn’t gone through regular maintenance and the “check engine” light is illuminated on the dashboard, your automobile may fail the vehicle-emissions test.


What Do They Check for in a Car Inspection?

A licensed examiner performs a car inspection at state-approved examination stations only. This is what they will look for:

  • Front lights: front lights check to ensure proper 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 indications of damage and if there is a need for replacement
  • Mirrors: Check to make sure no mirrors are cracked, damaged or missing
  • Seat belts: to evaluate seat belts’ condition and make sure they are safely working or need replacing
  • Brakes: an in-depth brake evaluation to ensure proper brake action and if there is any 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?

Depending on the state, city, and region where the vehicle examinations are conducted, the automobile safety inspection period might vary. However, for most vehicles, this procedure normally takes one hour to an hour and a half.
