How long are inspection stickers valid in Maine?

In Maine, inspection stickers are valid until the end of the month in which the vehicle was inspected. This means that if a vehicle receives its inspection at any point during a month, the sticker will remain valid until the last day of that same month in the following year. This provides a clear timeline for vehicle owners, indicating the need for a new inspection that aligns with the expiration at the end of the month, rather than the end of the calendar year or for a full 12 months from the inspection date. It encourages timely maintenance and safety checks, ensuring that vehicles are inspected regularly to comply with state regulations.
