Now that the emissions is done, you may begin the full safety inspection. Inspect the wiper blades for tears then open the hood. Make sure the battery is safely secured and held down tight. While you'reunder the hood, take a look at the belts and check the engine fluids and note down any problems you may find. Also check for the emissions components under the hood such as the pcv valve, air pump (if originally equipped), the EVAP canister and any broken vacuum lines. A loose battery hold down or torn wipers will fail the safety inspection. Also if the hood latching mechanism is not working properly, this will fail safety too. Remember, even though a car may have passed the emissions test, missing or incorrectly emissions components will fail the safety inspection.
