UK Motorcycle Theory Test Safety Equipment 2 — Questions and Answers
Question 1: What is a back protector and why should motorcyclists use one?
- A seat cushion for long rides
- An armoured panel worn on the back to protect the spine from impact injuries in a crash (Correct answer)
- A reflective patch for the back of the jacket
- A lumbar support for posture
Correct answer: An armoured panel worn on the back to protect the spine from impact injuries in a crash
A back protector is an impact-absorbing armoured panel that protects the spine during a crash. Spinal injuries can be catastrophic and permanent. Back protectors are rated CE Level 1 or Level 2, with Level 2 providing superior protection.
Question 2: How often should a motorcycle helmet be replaced even if it has not been in a crash?
- Never — helmets last forever
- Every 5 years, as materials degrade over time from UV exposure, sweat, and general wear (Correct answer)
- Every 20 years
- Only when the visor scratches
Correct answer: Every 5 years, as materials degrade over time from UV exposure, sweat, and general wear
Helmet manufacturers typically recommend replacement every 5 years. The EPS liner, shell material, and comfort liner degrade over time from UV exposure, temperature changes, sweat, hair products, and general wear, reducing the helmet's protective capability.
Question 3: What is the purpose of a visor on a motorcycle helmet?
- Decoration only
- To protect the rider's eyes and face from wind, rain, insects, road debris, and UV radiation (Correct answer)
- To make the helmet heavier
- To reduce hearing
Correct answer: To protect the rider's eyes and face from wind, rain, insects, road debris, and UV radiation
The visor protects the rider's face and eyes from wind, rain, insects, stones, road spray, and UV radiation. It must be kept clean and scratch-free for clear vision. A tinted visor must not be used at night or in poor visibility conditions.
Question 4: What is the minimum legal tyre tread depth for motorcycles in the UK?
- 0.5mm
- 1mm across 75% of the breadth and around the entire circumference (Correct answer)
- 1.6mm
- 2mm
Correct answer: 1mm across 75% of the breadth and around the entire circumference
Motorcycle tyres must have at least 1mm of tread depth across three-quarters (75%) of the breadth of the tyre and in a continuous band around the entire circumference. The remaining 25% must have a visible tread pattern. Using tyres below this limit is illegal and dangerous.
Question 5: Why is it important to check tyre pressures regularly on a motorcycle?
- Tyre pressure never changes
- Incorrect pressure affects grip, handling, braking, and tyre life — critically important with only two contact patches (Correct answer)
- Only rear tyre pressure matters
- Tyre pressure only affects comfort
Correct answer: Incorrect pressure affects grip, handling, braking, and tyre life — critically important with only two contact patches
A motorcycle has only two small contact patches with the road. Incorrect tyre pressure drastically affects grip, handling, braking distance, and tyre wear. Under-inflated tyres can overheat and fail; over-inflated tyres reduce the contact patch and grip. Check pressures weekly when cold.
Question 6: What should you check on your motorcycle chain during routine maintenance?
- Nothing — chains are maintenance-free
- Chain tension (correct free play), lubrication, and wear (elongation and sprocket tooth condition) (Correct answer)
- Only the colour of the chain
- Just whether the chain is still attached
Correct answer: Chain tension (correct free play), lubrication, and wear (elongation and sprocket tooth condition)
A motorcycle chain should be checked for correct tension (typically 20-30mm of free play at the tightest point), adequate lubrication, signs of wear (stretched links, stiff spots), and sprocket condition (hooked or worn teeth). A failing chain can cause serious injury.
