Are tractors allowed on the motorway?
19th March 2025
Farmers and contractors often need to move tractors and machinery between sites, sometimes covering significant distances. While country roads and A-roads are commonly used, many wonder: can tractors legally travel on motorways in the UK?

In short, the answer is no. This is explicitly stated in the Highway Code, and is covered by the Road Traffic Act 1988. Motorways are specifically designated for “fast-moving” traffic, and tractors, with their lower speed limits and wider designs, pose a potential safety risk to other motorway users.
Certain other slow-moving vehicles, such as mobility scooters and bicycles, are also banned from motorways for similar reasons. The general rule is that if a vehicle cannot maintain a constant speed of at least 50mph, it should not be on a motorway.
Why tractors are banned from the motorway
- Speed and traffic flow – Most tractors have a top speed limit of between 20-40mph, well below motorway speed limits. This would cause major disruptions to fast-moving traffic.
- Safety concerns – Motorways are designed for road vehicles that can accelerate and decelerate rapidly; therefore, slow-moving tractors present a hazard, particularly when merging or crossing slip roads.
- Vehicle suitability – Tractors are designed for rough terrain, meaning they may not handle motorway conditions well. Additionally, some tractors lack the necessary lighting, mirrors and indicators required for safe motorway use.
Alternative solutions for moving tractors
If a tractor or large piece of machinery does need to be transported over a long distance, there are several legal and practical alternatives:
- Low loaders and transporters – a commonly adopted method is loading tractors onto a flatbed or low-loader trailer.
- A-road routes – while slower, sticking to A-roads and major B-roads ensures legality and minimises disruption.
- Farm-to-farm coordination – some farmers coordinate with others to help reduce unnecessary long-distance travel.
In summary, while the idea of taking a tractor on the motorway might seem like a tempting shortcut, it is illegal and unsafe. Farmers and contractors should plan routes accordingly, ensuring compliance with UK road laws and prioritising safety for themselves and other road users.
