Driving Hours, Rest, Tachographs and Fatigue
Why hours are regulated
Fatigue is a major cause of heavy vehicle crashes. Rules on driving time, breaks and daily and weekly rest exist to keep drivers alert. Candidates should understand the structure: a maximum continuous driving period before a break is required, minimum break length, daily driving limits, and weekly limits with rest between them. Know that waiting time and other work count differently from driving, and that the record must reflect reality.
Tachographs
A tachograph records driving, other work, availability and rest. Drivers must use it correctly, select the right mode, keep records for the required period, and produce them for inspection. Manual entries must be accurate. Tampering, falsifying records or using another person's card is a serious offence.
Fatigue management
Plan rest before you feel tired, take breaks, avoid driving when sleep-deprived, and recognise warning signs: yawning, heavy eyes, drifting, poor concentration. Opening a window or turning up the radio does not cure fatigue; stopping and resting does.
Traps
Questions often present a legal but unsafe plan, such as starting a long shift after little sleep. The right answer protects safety. Another trap is assuming a break can be taken while loading or fuelling; the mode recorded must match what you actually did.
Rule of thumb
If you feel sleepy, stop at the first safe place and rest. No schedule is worth a crash.
Worked example
You have driven for several hours and feel drowsy. Correct: stop at a safe location, record rest, and take a proper break before continuing. Pressing on to reach the depot is wrong.
