| Farm vehicles on the roads After receiving a complaint regarding an abnormally wide agricultural vehicle on a public road that was not complying with legislation, we ask you to please ensure that you comply with legislation in respect of using agricultural vehicles on public roads. AGRICULTURAL TRACTORS: a brief guide The maximum width of a tractor (or trailer) is 2.55m. Certain essential parts such as lights and mirrors can be ignored when measurement of width takes place. Under special circumstances Agricultural vehicles wider than 2.55m are permitted to use public roads. The Road Vehicles (Authorisation of Special Types) (General) Order 2003 (known as SAGO) permits the road use of Agricultural vehicles that are up to 4.3 metres in width, subject to terms and conditions. The key ones are as follows: Width – between 2.55m and 3m: speed must not exceed 20mph. Width – between 3m and 3.5m: maximum speed 20mph as above, plus if the journey is over 5 miles or the speed limit in the road is 40mph or lower, (or both), the operator must notify the Police in advance of the journey. Width - between 3.5m and 4.3m: the Police must be notified, the maximum speed is limited to 12 mph and the vehicle(s) must be accompanied by an attendant, who may ride in a different vehicle but must ensure no danger is caused to the vehicle or other road users. The police, following notification, may place restrictions on the use of the vehicle in the interests of road safety or to avoid undue traffic congestion. |
