Agricultural Tractor (mounted on wheels) & Trailer (Cat.F){Cat.F does not have a +E sub category}
C&U: Maximum weight = 24 390 kg, So a loaded trailer with a 12000kg capacity,
unladen weight of 5900 kg towed by a tractor weighing 6500 kg
would be overweight for the public highway.*
Agricultural tractors for C+U and STGO purposes may be defined as
Motor Tractors (<7370kg) or Locomotives (>7370kg)
[1991 advice: The minimum age for driving an AMV / land locomotive over 7370kg unladen weight is 21 years.]
Agricultural motor vehicle maximum length = 12 metres
When towing 2 or more trailers maximum length of towing AMV reduces to 9.2 metres
Agricultural vehicle combination (one trailer) maximum length = 18.75 metres
Agricultural vehicle combination (two trailers) maximum length = 25.9 metres
Only one trailer may exceed 7 metres
A locomotive may tow three trailers - all trailers must be 7 metres or less
When towing 2 or more trailers they must be unladen
Agricultural vehicle combination maximum width = 2.55 metres
This may be exceeded providing conditions are complied with*.
2.55 - 3 m = 20 mph speed limit
3 - 3.5 m = 20 mph speed limit + police notification (24 hours before journey)
3.5 - 4.3 m = 12 mph speed limit + police notification (24 hours before journey) + ■■■■■■ required
If you only hold provisional entitlement to category f you may drive unaccompanied
as long as your tractor is not constructed or adapted to carry any passenger:
Tractors with passenger seats require provisonal licence holders to be accompanied
by a full licence holder who has held the category for 3 years and is at least 21 years old.
Most categories require a full licence to tow a trailer.
You may tow a trailer with a category f provisonal licence.
(At age 16, with a category f provisonal licience you may only drive on the road when
going to, taking or returning from the driving test.)
At 16 you are restricted to a maximum width of 8’ (2.43m) and any trailer towed must be
either 2 wheeled or 4 wheeled close coupled type i.e. the axle centres are no more than 840mm (~32") apart.
Provisonal licence holders must display L-plates.
