Traffic on motorways usually travels faster than on other roads, so you have less time to react. It is especially important to use your mirrors earlier and look much further ahead than you would on other roads.
Prohibited vehicles. Motorways MUST NOT be used by pedestrians, holders of provisional motorcycle licences, riders of motorcycles under 50 cc (4 kW), cyclists, horse riders, certain slow-moving vehicles and those carrying oversized loads (except by special permission), agricultural vehicles, and powered wheelchairs/powered mobility scooters (see Rules 36 to 46 inclusive).
Provisional car licence holders MUST NOT drive on the motorway unless they are accompanied by a DVSA Approved Driving Instructor (ADI) and are driving a car displaying red L plates (or D plates in Wales) with dual controls.
