Mobility scooters and powered wheelchairs, sometimes called invalid carriages, are covered separately in the Highway Code because they behave differently from both pedestrians and vehicles. They're generally slower than traffic but not classed as pedestrians when used on the road, which creates specific rules about where they can travel and how drivers should treat them.
This is a smaller topic on the theory test, but it turns up in multiple-choice questions about vulnerable road users and speed limits for different classes of vehicle, so it's worth knowing the basics precisely rather than guessing.
Two classes of vehicle
Class 2 scooters are the smaller, pavement-only type with a maximum speed of around 4mph and are treated like pedestrians when used on a pavement. Class 3 scooters are larger, road-legal machines with a maximum speed of around 8mph on the road, and they must display a flashing amber beacon on faster or dual-carriageway roads.
Where they're allowed to travel
Class 2 scooters should generally stay on pavements and only cross roads at appropriate points, while Class 3 scooters can use the road as well as the pavement, switching to a slower speed automatically or manually when on pavements. Neither class is permitted on motorways.
How drivers should respond
Because these vehicles are slow and often used by people with limited mobility, drivers should be patient, avoid overtaking too closely, and allow plenty of time when one is crossing or joining the road. A driver shouldn't assume a mobility scooter can accelerate out of the way quickly, so leave a generous gap.
Visibility considerations
A flashing amber beacon on a Class 3 scooter indicates it's operating on a faster road and needs to be given the same courtesy as a slow-moving vehicle, not treated as a hazard to rush past.
Frequently asked questions
What is the difference between a Class 2 and Class 3 mobility scooter?
A Class 2 scooter is pavement-only with a top speed of around 4mph and is treated like a pedestrian. A Class 3 scooter can also use the road, has a top speed of around 8mph, and must show a flashing amber beacon when used on faster roads.
Are mobility scooters allowed on motorways?
No, mobility scooters and powered wheelchairs of either class are not permitted on motorways under any circumstances. They're restricted to pavements and ordinary roads depending on their class.
How should I drive near a mobility scooter on the road?
Treat it as a slow-moving vehicle, leave plenty of space, and be patient rather than overtaking closely or expecting it to speed up. Give extra time if it's crossing or joining the road.
What does a flashing amber beacon on a mobility scooter mean?
It shows the scooter is a Class 3 type being used on a faster road, which needs greater visibility. Drivers should treat it the same way as any other slow vehicle showing a hazard warning.
Can a Class 2 mobility scooter be used on the road?
Only briefly, such as to cross the road at a safe point, since it's designed primarily for pavement use at a low top speed. It should not travel along the main carriageway.
