MOT Bay

Class 4 MOT Bay dimensions with MOT Ramp

Height requirement – This can be confusing at times so the easiest way to explain this is if you were to imagine a glass box around your MOT ramp.

The glass box must be extended 500mm from the outer edges of each platform left and right, 500mm to the rear of the ramp and 1000mm out from the drive on the end of the ramp. This glass box must be 3800mm high.

If that glass box fits where the ramp is to be installed, then the height is not a problem. If anything enters the glass box, this is a problem and it may cause DVSA (Driver and Vehicle Standards Agency) to reject your application. There may be a solution should you face this problem by using a slightly different configuration on the layout of the MOT bay, but this is dependent on the space available within your premises.

Some more essential MOT Bay dimensions to know

  • The overall width of a class 4 MOT bay is 3600mm
  • A 600mm clearance all around the MOT bay is required 
  • Vehicle entrances and exits must be a minimum of 2400mm in height and wide
  • Headroom over lift 3800mm as explained above
  • Headroom over remaining mot bay minimum 2400mm
  • Brake test standing area width 2400mm
  • Brake test standing area length 9000mm – This can be part of your ramp if the ramp is recessed into the floor and level with your roller brake tester

 

Class 4 MOT Bay dimensions with a Pit

Height requirement – When using an inspection pit instead of a ramp then the height considerably reduces from 3800mm to 2400mm.

The use of a pit may be the only option available to you if you don’t have the required height or width within your premises.

Again, using the glass box to help, you will need to imagine your glass box 3600mm in width and 2400mm high the whole length of your MOT bay. If that glass box fits, then there is no issue.

Inspection Pit size requirements

  • A working length of at least 3900mm
  • A width of at least 760mm and not more than 920mm over the working length measured across both pit walls
  • A depth of at least 1500mm and not more than 1800mm, over the working length
  • Adequate access for personnel to enter the pit which does not intrude on the working dimensions

When thinking about the layout of your new MOT bay whatever class of vehicle you wish to test, it’s always good practice to think about what you wish to do with the rest of the space you have available. For example, do you want to install a tyre-changing machine and wheel balancerwheel alignment machine or other garage ramps or vehicle lifts?

Depending on your plans this could alter the way the MOT bay is configured. The MOT bay can be inline or side by side it may also include the option to carry out wheel alignment on your MOT equipment.

It’s always recommended to have your chosen equipment supplier conduct a site survey and discuss all your options available to you. This should then be backed up with a CAD design layout drawing. The drawing is a requirement of DVSA as part of your VT01 application also.
