Occasionally, a vehicle will not pass inspection, which can be for various reasons. For the safety inspection, your car will be tested on a variety of requirements, including the function of headlights, directional signals, steering, windshield wipers, and brakes. If your vehicle needs new wipers, for example, we will inform you and replace them on the spot. The emissions test is part of Auto Pro’s goal to limit ozone-forming emissions from cars and trucks to protect the environment.
