If you're driving under EU rules, you mustn't drive continuously for more than four-and-a-half hours without taking a break. If you've driven continuously for four-and-a-half hours, you must take a break of at least 45 minutes. Include your stops in the timetable when planning your journey.

If seat belts are fitted to your lorry, you must wear them. Exemptions are allowed for holders of medical exemption certificates and for delivery drivers when travelling less than 50 metres (162 feet).

It's dangerous to drive a vehicle with low air pressure. To alert you to this, all vehicles are fitted with a warning light and/or buzzer. Don't move your vehicle if this warning shows or sounds.

You must show consideration to other road users. Elderly drivers may have slower reactions and they might need more time to deal with a situation. Be tolerant and don't lose patience or show your annoyance.

Noise, vibration, exhaust emissions and fuel consumption all contribute to the environmental impact made by a lorry. Good anticipation and forward planning will help to reduce these effects. Braking in good time saves fuel and so helps reduce exhaust emissions. It also helps reduce wear on the vehicle, its tyres and the road surface.

A bus equipped with a speed limiter must also be fitted with a plate showing the speed setting. This must be fitted in an obvious position, where it can be clearly seen.

Current legislation requires all operators to set up an 'effective system' to help prevent the carriage of illegal immigrants. This should include vehicle security and checking using a checklist. Failure to do this will incur penalties.

The main causes of lorries shedding their loads are driver errors, such as sudden changes of speed or direction, driving too fast for the conditions, and harsh braking.

It's an offence to leave your vehicle unattended at any time without applying the parking brake.

Driving today requires all of your attention, all of the time. Any distraction, however brief, is dangerous. This is why it's illegal to use a hand-held mobile phone while you're driving.

Drag is caused by wind entering the cavity of an uncovered tipper. If the cavity is covered, then the drag is reduced.

Take your time when you're using walkways at high levels. Spilt fuel can make the surface slippery and increase the risk of falling.

The national speed limit for a goods vehicle exceeding 7.5 tonnes on a single carriageway road in England and Wales is 50 mph. In Scotland, the limit is 40 mph. The national speed limit varies for different vehicle categories. You must know the limit that applies to the vehicle you're driving.

Moisture in the air condenses as the air pressure increases. This moisture can be transmitted around the braking system and is especially dangerous in cold weather. It can lead to ice forming and blocking the valves and pipes.

The red emergency line is common to both two-line and three-line braking systems. Always set the parking brake before disconnecting any brake line.

You must take 35 hours of training every five years to maintain your Driver CPC. This can be done at any time during the five years: all at once or split into sessions of at least seven hours each. The penalties for non-compliance are the same as those for driving without a licence.
