LGV - Free Theory Test 1

If you know which light is going to show next, you can plan your approach. This will help prevent excessive braking or hesitation at the junction.

You must be able to stop safely in the distance that you can see to be clear ahead. This will be the distance illuminated by your headlights or by street lights and will generally be less than you can see in daylight.

Before overtaking assess the situation. Look well ahead to see if the cyclist will need to change direction. Be especially aware of the cyclist approaching parked vehicles as they will need to alter course. Do not pass too closely or cut in sharply.

Always maintain a safe following distance from the vehicle in front. If another vehicle pulls into the gap, slow down to re-establish a safe following distance. Following too close is dangerous and places you and other road users in unnecessary danger; your view of the road ahead will be seriously reduced, and you won't be able to see or plan effectively.

Air suspension reduces the pounding of the vehicle on an uneven road surface. This, in turn, reduces the vibrations transmitted to buildings and underground services along the route.

Coolant solution is also known as anti-freeze. It provides protection from freezing and also contains a corrosion inhibitor that prolongs the life of the cooling system. Remember to check the coolant level regularly.

Prepare to slow down and stop, as you would for a person without a disability. Don't wave them across, as other traffic may not stop.

You should allow the faster-moving vehicle to overtake safely. If you pull out to overtake at this time, you'll cause the car behind to brake sharply. Don't use the size of your vehicle to intimidate. Be professional and show consideration to other road users.

If the steering becomes heavy, the power-assisted steering may have failed. It's also possible that your vehicle has a puncture or the load might have shifted. You should stop safely, investigate the cause and call for help if necessary.

Use of the right-hand lane on motorways with three or more lanes isn't normally allowed for

• vehicles over 7.5 tonnes maximum authorised mass
• vehicles required to be fitted with a speed limiter
• vehicles towing a trailer.

This rule does not apply in special circumstances, such as when the left-hand lane is closed.

Always have wheel nuts checked soon after their initial tightening. They should be tightened to the torque specified by the vehicle manufacturer.

Projection marker boards must be fitted if the load on your vehicle overhangs by more than 2 metres (6 feet 6 inches). This will help other road users who may not notice the projecting load.

If the air-pressure warning activates, you should have enough air to allow you to stop safely on the hard shoulder. Don't delay stopping, as further loss of air may cause the brakes to lock on. Switch on the hazard warning lights. Use the nearest emergency telephone to call for assistance.

Many learners aren't confident when they first start to drive. Allow them plenty of room and don't react impatiently when they take their time. Remember that new drivers are inexperienced in dealing with traffic situations, so be patient.

Major roadworks often cause complicated diversions for large vehicles. Drivers may be advised to follow a special symbol until the original road can be rejoined. Look for the yellow-and-black symbols in these shapes:

• square
• triangle
• diamond
• circle.

They'll often be shown with additional information and will help guide you around the diversion.

You must obey these signs even if there appear to be no problems ahead.

Flashing amber lights are found near schools. They warn you that children are likely to be crossing the road on their way to and from school. Drive slowly until you're clear of the area.

On a poor road surface, the rider may need to move out to avoid potholes. You may not get much warning. A look to the right or a 'lifesaver' check may warn you that they're about to move out. Stay well back and allow the rider plenty of room until you can pass safely.

It's important to keep a safe distance from the vehicle in front at all times. This still applies in congested tunnels, even if you're moving very slowly or have stopped. If the vehicle in front breaks down, you may need room to manoeuvre past it.
