For what duration are the inspection stickers valid?

Inspection stickers in Missouri are valid for one calendar year. This means that once a vehicle passes its safety inspection, the sticker issued indicates that it is approved for operation on the road for the remainder of that calendar year. Typically, vehicle owners are required to have their vehicles re-inspected annually to ensure they continue to meet safety standards. It's important for vehicle owners to keep track of this timeframe to avoid penalties or potential safety issues related to their vehicle's condition.

While some other states may have different durations for vehicle inspections or may assess vehicle condition at different intervals, the one-year validity in Missouri aligns with the intention of maintaining regular safety checks and compliance.
