Your vehicle has a maximum authorised mass of 40 tonnes. The kerbside weight is 15 tonnes. What's your maximum payload? Correct Answer: B 25 tonnes Explanation: Overloading a vehicle is dangerous. Your stopping distance will increase, and your vehicle could become unstable and difficult to control. You'll need to work out the payload.

Do this by taking away the kerbside weight from the maximum authorised mass MAM. This will give you the maximum weight you can carry. You're making several deliveries. What problems may the decreasing payload cause? Correct Answer: B You might overload an axle Explanation: As items are unloaded from the rear of the vehicle, weight will be transferred to the front axle.

Take care that this axle doesn't become overloaded. You may need to redistribute the load. Your lorry is fitted with a driver's seat belt. When may you drive without wearing it? Correct Answer: B When you're making deliveries that are less than 50 metres apart Explanation: It's compulsory for drivers and passengers to wear seat belts. However, if you're making deliveries that are less than 50 metres apart, you may leave the seat belt undone.

It would be impractical to keep fastening and unfastening your seat belt over such short distances. Which symbol on a lorry means it's likely to be carrying compressed gases?

Correct Answer: A 10 times Explanation: It's vital that you give yourself enough separation distance when driving on icy roads - ten times as much as in normal conditions.

You should brake gently to reduce the risk of losing control. What can happen to drivers who break EU tachograph regulations? Correct Answer: B They can be heavily fined Explanation: The driver must take responsibility and follow the drivers' hours and tachograph rules. Failure to do so can result in legal action and penalties - such as a fine. The analogue tachograph on your vehicle becomes faulty.

How long do you have before you must have it repaired? Correct Answer: B One week Explanation: If the tachograph on your vehicle becomes faulty, you should take it to an approved tachograph repairer as soon as possible. If you can't return to your base within a week of finding the fault, it must be repaired while you're away. While the tachograph is faulty or broken, you must keep a manual record of your activities. You're approaching a bridge that has no height restriction on it.

What's the minimum height under the bridge? Correct Answer: D 5 metres [16 feet 6 inches] Explanation: The headroom under bridges in the UK is at least 5 metres [16 feet 6 inches], unless otherwise stated. Where the overhead clearance is arched, this headroom is normally only between the limits marked.

You arrive at an incident where someone is suffering from severe burns. What should you do to help? Correct Answer: C Douse the burns with cold water Explanation: Cold water will cool the burning tissue and help prevent further damage. It will also reduce swelling, minimise shock and alleviate pain.

Use water, or any other liquid, that's clean and non-toxic. What should you do if you notice that two wheel nuts are missing from one of the wheels on your vehicle?

Correct Answer: C Park and phone for assistance Explanation: If you notice any missing wheel nuts, park and phone for assistance.

Checks should be made before you start any journey, but make a visual check every time you start up again after a rest stop.

What would be illegal? Correct Answer: C Using a tyre with exposed ply or cord Explanation: You should check your tyres as part of your routine check of the vehicle. A damaged tyre - such as one with exposed ply - can have a major effect on your vehicle's handling and will make it a danger to you and other road users.

What proportion of the width of a tyre must have at least the legal minimum depth of tread? Correct Answer: D Three-quarters Explanation: Keeping your vehicle's tyres in good condition will give them a good grip on the road and will improve the vehicle's overall stability. Each tyre must have at least the minimum legal depth of tread across three-quarters of its width. Renew tyres well before they wear to less than that.

Correct Answer: D With-flow bus and cycle lane Explanation: Some lanes are set aside for certain types of vehicle.

Signs and road markings show the authorised vehicles in words or pictures. There's usually also a sign showing the times that the lane is in operation.

Some lanes might only be in operation for a short time. Check the sign and only use the lane if you're allowed to do so. Correct Answer: D Water across the road Explanation: This sign is found where a shallow stream crosses the road.

Heavy rainfall could increase the flow of water. If the water looks too deep or the stream has swelled over a large distance, stop and find another route. Which large vehicles are more likely to damage the road surface? Correct Answer: D Vehicles with faulty suspension Explanation: Suspension faults may result in road damage. Road-friendly suspension reduces the impact on the environment, the road surface and under-road services.

Who has priority when you're approaching this sign? Correct Answer: B Oncoming traffic Explanation: When you see this sign, you must give way to traffic from the opposite direction, regardless of the size of your vehicle.

Why should you be aware of motorcyclists on a motorway when there are gusty winds? Correct Answer: A They may be blown into your path Explanation: On motorways, there are often exposed stretches of road where vulnerable vehicles can be affected by side wind. A gust of wind can even blow a motorcyclist out of their lane.

Try to anticipate how the wind may affect others and give them plenty of room. You're overtaking a motorcycle in windy conditions. Why should you check your nearside mirror?

Correct Answer: D To see if the rider is in control of their motorcycle Explanation: You must check the nearside mirror during and after overtaking a motorcyclist. Make sure that the rider is still in control and that your vehicle's draught hasn't caused them to lose their balance. What's the greatest risk to your safety when you're overtaking on a motorway in very wet weather? Correct Answer: D Your tyres may lose grip Explanation: In very wet conditions, tyres may be unable to clear all the water from their path.

This can result in a layer of water building up between the road and the tyre - a situation known as aquaplaning. To regain control, ease off the accelerator and, as the vehicle slows, the tyres should regain their grip.

It's safer to reduce the risk of aquaplaning occurring by driving more slowly in very wet weather. What should you be aware of when you're overtaking on a motorway while it's raining heavily? Correct Answer: C Visibility will be reduced by spray from traffic Explanation: Other road users can be affected by the spray from large vehicles, severely reducing their vision.

However, you mustn't rely on them to get you out of trouble or expect to be able to make sudden direction changes if you're going too fast. When should an endurance brake retarder be used? Correct Answer: A On long downhill slopes Explanation: An endurance brake can help to control your speed on long downhill slopes without using the service brake.

Reducing the use of the service brake helps to prevent the brakes from overheating and reduces the risk of brake fade. What should you do if you're signalled to stop by a police officer in a patrol car? Correct Answer: D Stop on the left as soon as it's safe Explanation: If a police officer signals for you to stop, stop as soon as possible in a safe place on the left. Your vehicle is fitted with a hand-held telephone. What should you do before taking or making a call?
