Q1. Before riding a moped or motorcycle on the road as a learner, what must you complete first?

A. Compulsory Basic Training (CBT)
B. A motorway driving lesson
C. An advanced riding course
D. A first aid certificate

Show answer & explanation

✓ Answer: A. Compulsory Basic Training (CBT)

CBT is a legal requirement before riding on public roads with L plates. It covers basic machine control, on-road riding and safety awareness. There is no legal requirement to complete a motorway lesson, advanced course or first aid certificate before riding as a learner.

Q2. What is the legal minimum standard a motorcycle helmet must meet to be worn on a public road in Great Britain?

A. It must simply carry a CE mark of any kind
B. It must be purchased new and less than five years old
C. It must be approved by the rider's insurance company
D. It must be secured to the head and comply with British Standard BS 6658:1985 (or a UNECE Regulation 22 equivalent, or comparable EU standard)

Show answer & explanation

✓ Answer: D. It must be secured to the head and comply with British Standard BS 6658:1985 (or a UNECE Regulation 22 equivalent, or comparable EU standard)

UK law (Motor Cycles (Protective Helmets) Regulations) requires a helmet to meet BS 6658:1985 or an equivalent recognised standard such as UNECE Reg 22, and to be fastened. A generic CE mark alone isn't sufficient proof of compliance, and there's no insurer approval scheme or fixed age limit in law.

Q3. When checking tyre condition before a ride, what is the minimum legal tread depth for a motorcycle tyre over 50cc across the central three-quarters of the tread, measured around the entire circumference?

A. 1mm
B. 1.6mm
C. 2mm
D. 2.5mm

Show answer & explanation

✓ Answer: A. 1mm

UK law requires a minimum tread depth of 1mm for motorcycles over 50cc, measured across the central three-quarters of the tyre's breadth and in a continuous band around the entire circumference. Mopeds of 50cc and under only need a visible tread pattern across the full breadth and circumference. The 1.6mm figure is the car/light-vehicle standard and does not apply to motorcycles, so option (1mm) is the correct legal minimum here.
