Class 4 MOTs need to be taken once every 12 months

• Tyres  
• Lights 
• Seats 
• Exhaust system

Compared to Class 4 MOTs, Class 7 vehicles require a different MOT test, which is taken every six months. As large vans and trucks are frequently used, your van may succumb to wear and tear over time. A Class 7 MOT test will cover: 

• The vehicle's bodywork
