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.
