So what is an MOTT you may wonder?. An MOTT is a legal requirement for all cars, vans, light commercial vehicles and goods vehicles up to and including 3500kgs. The MOTT is required when a vehicle is three years old and every year thereafter. All MOTT'S carried out at our MOT Salisbury test centre are carried out by qualified MOT Salisbury testers to Driver and Vehicle Standards Agency (DVSA) standards. For a vehicle to pass its MOTT the vehicle must reach the MINIMUM road safety criteria as set out by the DVSA.
