You can have your MOT test conducted up to one month before your current certificate expires, as long as you present your existing valid MOT certificate to the examiner during the test, this early testing won’t affect your current expiry date, so there’s no need to wait until the last minute and risk a panic situation. If your vehicle is over three years old, you’re legally required to maintain it in a safe and roadworthy condition, and the MOT test serves as the official check to ensure your car meets the necessary road safety and environmental standards.
