How to pass emissions test for car

If you’re about ready to get your car inspected for vehicle emissions, here are some helpful tips that will help your car pass the inspection.

Tips for passing emissions test:

  • Fast idle your engine for about 30 seconds immediately before you drive into the inspection facility.
  • Ensure your seatbelt is buckled (including all passengers).
  • Drive your car around for 10-15 minutes prior to entering emissions testing so it is at peak efficiency.
  • Turn off your air conditioning, heater, radio, or other accessories before the inspection starts.
  • Check your turn signals, lights, horn, and wipers before inspection and repair if they aren’t working.
  • If you have a engine maintenance light on, go and get that checked out by your mechanic before having the emissions tested.
  • Ask the DMV inspector for assistance or tips if you fail the inspection.
