Taxi testing for heavier vehicles

If you are applying for a Class C taxi licence with a heavy vehicle (over 3,500kg gross weight or over 2,540kg unladen weight), there are some extra features that you need to be aware of as well as the standard rules for a Class C application.

Class C rules for heavy vehicles

Some of the standard Class C rules which apply to heavy vehicles include:

  • a maximum of eight passenger seats
  • a maximum passenger step height of 435mm
  • a suitable fire extinguisher mounted and readily available for use
  • two doors - one on the nearside and one on the offside or the rear
  • valid taxi insurance

Heavy vehicles don't have to be M1 type approved, and may be altered since they were originally made.

More detailed guidelines for all taxis can be found at the link below:
