Question

Difficulty: MediumMotorway Restrictions and Prohibited Users

To maintain safe traffic flow and reduce the risk of collisions caused by extreme speed differentials, UK motorway regulations prohibit specific road users and vehicle types. Which of the following vehicles is legally permitted to travel on a motorway?

  1. A
    A moped with an engine capacity of 49 cc ridden by a full licence holder
  2. A 125 cc motorcycle ridden by a rider holding a full motorcycle licenceAnswer
  3. C
    An agricultural tractor travelling between farm fields
  4. D
    A Class 3 powered mobility scooter with a maximum speed capability of 8 mph

Answer

A 125 cc motorcycle ridden by a rider holding a full motorcycle licence
Under UK Highway Code Rule 253, motorways must not be used by motorcycles with an engine capacity under 50 cc. A 125 cc motorcycle ridden by a full licence holder satisfies both the minimum engine capacity requirement and licence conditions, making it legally permitted.

Step-by-Step Solution

1
Identify the vehicle and road user exclusions set out in Highway Code Rule 253
Rule 253 bans pedestrians, cyclists, horse riders, agricultural vehicles, powered wheelchairs/mobility scooters, and motorcycles under 50 cc from motorways.
These road users either move too slowly or lack sufficient power to mix safely with high-speed motorway traffic.
2
Evaluate the capacity and licence criteria for the remaining vehicle category
A 125 cc motorcycle exceeds the 50 cc minimum capacity threshold and is being operated by a full licence holder.
This satisfies both the mechanical threshold and driver qualification requirements for motorway use.
