Horse riders often keep to the outside of the roundabout even if they're turning right. Give them room in case they have to cross lanes of traffic.

This is a warning sign to indicate loose chippings ahead. The sign is usually accompanied by an advisory speed limit. Vehicles travelling too fast for the conditions can throw up chippings or stones. Avoid causing damage to paintwork and windscreens by keeping your speed down.

Before leaving the cab, it's very important to secure the vehicle by applying the parking brake. After leaving the cab, apply the trailer parking brake.

There are times when other road users make incorrect or ill-judged decisions. Try to stay calm and don't retaliate or react aggressively, especially as your vehicle is likely to be larger and more intimidating than the other person's. Always put safety first.

Allow the cyclist plenty of room. Give them space and be prepared for them to change direction. To stay safe, they may travel around the roundabout in the left-hand lane.

The oil and filter will get dirty in normal use. If you follow the service-interval guidance, your engine will remain protected and properly lubricated, making it less likely to break down.

If the engine contains too much oil, the moving parts can hit the oil surface, causing a loss of power or even damage to the engine. Excess pressure may damage oil seals, causing oil to leak onto the road, creating a slippery and dangerous road surface.

Lack of oil could cause the engine to seize, and this could cause sudden and unexpected loss of control. You could break down in a dangerous position and put yourself and other road users at risk.

On a quiet country road, always be aware that there may be a hazard just around the next bend, such as a slow-moving vehicle or pedestrians. There might not be a pavement and people may be walking on your side of the road.

If any animal you pass on the road becomes unsettled, you should brake gently and come to a stop. A nervous animal is unpredictable, so you should wait until it has settled or passed by. Other road users behind you may have a limited view of the hazard, so use your mirrors and give clear signals if necessary.

Keeping the height of the load as low as possible will reduce the wind resistance of the vehicle. This will help to save fuel. It's particularly relevant when using a flat-bodied lorry or trailer.

Too much weight on an axle can reduce braking efficiency and cause brake fade. As well as being dangerous, exceeding the axle weight limit is an offence that can result in prosecution.

Side-wind warning signs are often found on roads that are frequently affected by strong wind. High-sided vehicles, caravans and motorcycles are more susceptible to windy weather, and you should be aware of the difficulties they may be having.

If you notice any missing wheel nuts, park and phone for assistance. It's essential that all wheel fixings are in place and tightened to the torque specified by the manufacturer. Checks should be made before you start any journey, but make a visual check every time you start up again after a rest stop.

Don't hurry elderly people across the road by getting too close to them or revving the engine. Be aware that they might take longer to cross. They might also have hearing difficulties and not hear you approaching.

Motorcyclists and cyclists may be more difficult to see, especially at junctions. They can be easily hidden by obstructions such as other vehicles, and the small size of an approaching motorcycle may make it difficult to judge its speed and distance. It's vital that you don't emerge until you're sure it's safe.

The forces acting on a lorry will try to move it in a straight line as it enters a bend. The greater the weight, the greater the force. If you're going too fast, there's a danger that you could lose your load or tip over.

The view you get in your mirrors may vary, depending on the size of the trailer and the load it carries. Always adjust your mirrors to ensure that you have the best possible view down each side of the trailer before you drive away.
