The Government has now extended is 'Get MOT reminders' service to include commercial vehicles, so if you own a lorry, bus or specialist vehicle you can register for the scheme here and then you will get free reminders 2 months before your MOT is due.
You’ll get another reminder if you still haven’t had your vehicle tested one month before its annual test is due.
