The MOT Testing Guide Requirements for Authorisation D Issue Date March 2019 63 1. Premises, Test Bay and Equipment Layout. The test bay and layout dimensions stated are the minimum requirements measured from the inside of walls and doors, as appropriate. If there is a capability to test longer wheel based vehicles i.e. if the lift will accommodate more than m wheelbase and the headlamp standing area is at the minimum requirements then the headlamp standing area dimensions will take precedence and am wheelbase would be the longest which could be tested. If a longer dimension is required then all other dimensions must be proportional to this, i.e. headlight standing area must be increased proportionally. 1.1 Premises, test bays and equipment will be considered suitable if they meet the requirements laid out in "Requirements for Authorisation for Vehicle Testing Station Common to all Classes.
