ADI Vehicle Loading 2 — Questions and Answers
Question 1: A load is protruding from the rear of a vehicle by more than 1 metre. What must the driver ensure?
- Nothing — any protrusion is acceptable
- The overhanging load must be made clearly visible, and if it extends more than 2 metres, it must be marked with a red flag or other prescribed marker and may require notification to the police (Correct answer)
- Only loads over 3 metres need marking
- The driver must obtain a special permit for any overhang
Correct answer: The overhanging load must be made clearly visible, and if it extends more than 2 metres, it must be marked with a red flag or other prescribed marker and may require notification to the police
Loads projecting more than 1 metre to the rear must be made clearly visible. If the projection exceeds 2 metres, the end must be marked with a red and white striped marker board or red flag. Projections over 3.05 metres require police notification, and over 3.66 metres require an attendant.
Question 2: When loading a vehicle, how should the weight be distributed?
- All heavy items should be placed at the rear for easier unloading
- Heavy items should be placed low and as close to the centre of the vehicle as possible, with the load distributed evenly side to side (Correct answer)
- Weight distribution does not matter
- All weight should be on one side for easier access
Correct answer: Heavy items should be placed low and as close to the centre of the vehicle as possible, with the load distributed evenly side to side
For optimal vehicle stability, heavy items should be placed low in the load space (lowering the centre of gravity), centred between the axles, and distributed evenly from side to side. Uneven loading can cause the vehicle to pull to one side, and top-heavy loading increases rollover risk.
Question 3: What is the driver's legal responsibility if an insecure load falls from their vehicle and causes an accident?
- The driver has no responsibility once the load falls
- The driver can be prosecuted for using a vehicle with an insecure load, face dangerous driving charges if injury results, and may be liable for damages in a civil claim (Correct answer)
- Only the person who loaded the vehicle is responsible
- The driver is only responsible if they loaded the vehicle themselves
Correct answer: The driver can be prosecuted for using a vehicle with an insecure load, face dangerous driving charges if injury results, and may be liable for damages in a civil claim
The driver is legally responsible for ensuring their load is secure. If an insecure load causes an accident, the driver may face prosecution under the Construction and Use Regulations, charges of driving without due care or dangerous driving, and civil liability for any injuries or damage caused.
Question 4: What effect does carrying passengers have on the way a vehicle handles compared to driving alone?
- Passengers have no effect on handling
- Additional passengers increase the vehicle's weight, which increases braking distances, affects acceleration, changes the suspension behaviour, and may require tyre pressure adjustments (Correct answer)
- Passengers improve the vehicle's handling by adding weight
- Only rear-seat passengers affect handling
Correct answer: Additional passengers increase the vehicle's weight, which increases braking distances, affects acceleration, changes the suspension behaviour, and may require tyre pressure adjustments
Passengers add weight that affects the vehicle's performance: braking distances increase, acceleration is reduced, the suspension compresses more (affecting ground clearance and headlight alignment), and tyre pressures may need adjusting. A full vehicle handles noticeably differently from an empty one.
Question 5: An ADI is teaching a learner about checking their vehicle before a journey with a loaded roof rack. What should be checked?
- Only that the items look secure from a distance
- That the roof rack is properly fitted, all fastenings are tight, the load does not exceed the roof rack's or vehicle's weight limit, items are individually secured, and nothing can come loose in the wind (Correct answer)
- Only the roof rack itself needs checking
- Roof racks are always safe if fitted by a professional
Correct answer: That the roof rack is properly fitted, all fastenings are tight, the load does not exceed the roof rack's or vehicle's weight limit, items are individually secured, and nothing can come loose in the wind
Before driving with a roof load, check: the rack is securely fitted to the vehicle's mounting points, all items are individually tied or strapped down, the combined weight does not exceed the rack's or vehicle's roof load limit, items are aerodynamically arranged, and nothing protrudes dangerously.
Question 6: What is the maximum overall height of a loaded vehicle that can use UK roads without special permission?
- 3.0 metres
- There is no legal maximum height, but drivers must be aware of low bridges (the standard UK bridge clearance is 5.03 metres or 16 feet 6 inches) and plan routes accordingly (Correct answer)
- 4.0 metres
- 6.0 metres
Correct answer: There is no legal maximum height, but drivers must be aware of low bridges (the standard UK bridge clearance is 5.03 metres or 16 feet 6 inches) and plan routes accordingly
There is no specific legal maximum height for vehicles on UK roads, but the standard bridge clearance is 5.03 metres (16'6"). Drivers of high vehicles must know their vehicle's height, plan routes to avoid low bridges, and be alert to height restriction signs. Bridge strikes cause significant disruption and are an offence.
