You don’t have to drive to the next town over to get it done. Here is what our technicians check during every Missouri state safety inspection:
Brakes
Pad depth, rotor condition, brake lines, and fluid level are all inspected to confirm your stopping power meets Missouri’s minimum safety standards.
Tires
We check tread depth, overall tire condition, and inflation on all four tires to make sure they meet the state’s requirements.
Lights
Every exterior light on your vehicle is tested, including headlights, brake lights, turn signals, hazard lights, and reverse lights. Any bulb that is not functioning will need to be replaced before your vehicle can pass.
Steering & Suspension
Steering components and suspension parts are inspected for wear, damage, or anything that could compromise your ability to control the vehicle safely on the road.
Horn, Mirrors & Windshield
Horn function, mirror condition, and windshield integrity, including wiper performance, are all checked as part of every inspection we perform.
Seatbelts & Airbag Warning Lights
Every seatbelt is tested for proper latching and retraction, and we verify that no airbag warning lights are active on your dashboard.
