In Missouri, the requirement for vehicle safety inspections is determined by the vehicle’s age. Newer vehicles are typically exempt for a period of time. The specific duration of this exemption is based on the model year of the automobile. Older vehicles, beyond a certain age threshold, are subject to regular inspections to ensure they meet safety standards.
The necessity for these evaluations is rooted in public safety. Regular examinations help to identify and correct potential mechanical issues before they contribute to accidents. This process can also contribute to environmental protection by ensuring vehicles meet emission standards. Historically, these programs have been implemented to reduce the number of accidents caused by faulty equipment and to maintain a safe driving environment for all motorists.
