In Missouri, all vehicles that are over five model years old require an annual safety inspection. This means if your car's model year is more than five years behind the current calendar year, you need to get it inspected every year. For example, in 2024, vehicles from model year 2019 and older must be inspected. Newer vehicles, from model year 2020 to 2024, are currently exempt from this mandatory safety inspection. However, certain counties in the St. Louis and St. Charles area also require an additional emissions test for vehicles registered there, regardless of age.
The safety inspection is a thorough check of your vehicle's key safety systems. A certified mechanic will examine components like brakes, tires, lights, steering, and windshield wipers to ensure they meet state safety standards. The goal is to confirm your car is roadworthy and poses no undue risk to you or others.
The cost of a safety inspection is regulated by the state and typically ranges from $12 to $50. If your vehicle fails, you have 60 days to complete the necessary repairs and have it re-inspected, often for a reduced fee. It's crucial to get your inspection done before your registration renewal month to avoid penalties.

Basically, if your car is more than five years old, you need a yearly safety check in Missouri. My 2018 SUV needed one this past spring. It's a quick process at any licensed inspection station. They check your brakes, lights, and signals to make sure everything's working right. Just get it done before your birthday month when your registration is due, and you'll be fine.

The rule is straightforward: the inspection requirement is based on the vehicle's model year. Take the current calendar year and subtract five. Any car from that model year or older needs an annual safety inspection. For instance, in 2024, the cutoff is the 2019 model year. This applies to most passenger vehicles. The only exception is for brand-new cars, which have a grace period for the first few years. Always check with the Missouri Department of Revenue for the most current rules.

I just went through this with my son's first car, a 2012 sedan. In Missouri, the magic number is five. Once a car hits its sixth model year, it has to pass an inspection annually. We took it to our local shop, and they checked the tires, horn, and even the seat belts. It cost us about fifteen bucks. It’s really about making sure older cars on the road are still safe to drive. It’s a good peace-of-mind thing, honestly.

Focus on the model year, not the year you bought the car. The law states that a vehicle becomes subject to mandatory annual safety inspections once it is five model years old. So, a 2020 model is exempt in 2024, but will need its first inspection in 2025. Remember, this is a safety inspection. Some metro areas also have separate emissions testing requirements. Keep your inspection receipt with your registration documents as proof of compliance.
