  4. What is the policy regarding drugs and driving?

    • BOnly prescription drugs are allowed
    • CSoft drugs are acceptable

    Answer: Any drug that impairs driving ability is illegal. Prescription drugs must not impair. Testing for illegal drugs is common.

  5. What medical conditions must be declared to the DVLA?

    • ADrivers do not need to inform the DVLA about any medical condition they have
    • BDeclaration is a personal choice, because a driver's medical history is private
    • CEpilepsy, diabetes, heart conditions, stroke, and others affecting safety
    • DOnly those conditions serious enough to require an overnight stay in hospital

    Answer: Certain conditions (epilepsy, diabetes, heart disease, stroke, etc.) must be declared. Driving with undeclared conditions can invalidate insurance.

  6. What is the procedure for drivers taking prescription medications?

    • ACheck if the medication impairs ability; adjust driving accordingly or stop
    • BMedicines a doctor prescribes call for the same approach as any other journey
    • CContinue driving without any change, since the prescription itself makes it lawful
    • DOnly inform the doctor

    Answer: Check medication side effects (drowsiness, dizziness, impaired vision). If impaired, don't drive or adjust work. Inform your doctor and company.

  7. What is fatigue and why is it dangerous?

    • AOnly affects elderly drivers
    • BOrdinary tiredness that a driver can work through; not a safety issue
    • CReduced alertness causing slower reactions and poor decisions
    • DCan be overcome by willpower alone

    Answer: Fatigue reduces alertness, reaction time, and judgment. It's a major cause of accidents. Only rest cures fatigue.

  8. How can a driver manage fatigue on long journeys?

    • ADrive during the day only
    • BKeep the cab warm
    • CDrink strong coffee at the services and carry on to the destination
    • DTake regular breaks, get proper rest, and use multiple drivers

    • AIt passes without consequence
    • BCan result in accidents, injuries, prosecution, and license suspension
    • CMinor issue
    • DOnly affects the driver

  11. What is the purpose of a medical examination for HGV drivers?

    • ATo check the driver's practical driving skills out on the road
    • BThey are unnecessary unless the driver has been injured at work
    • CIt is purely an insurance requirement set by the operator's insurer
    • DTo ensure the driver is fit to operate large vehicles safely

    Answer: Medical examinations ensure drivers are physically and mentally fit to operate HGVs safely. Vision, hearing, and health are checked.

  12. How should a driver declare health changes to the DVLA?

    • ATell the employer only, who will then pass it on to the DVLA
    • BTreatment of the condition removes any need to declare it
    • CInform the DVLA in writing and notify their insurance
    • DThe matter arises only if a police officer asks about it

    Answer: Changes in health (new conditions, medications, treatments) must be declared to the DVLA in writing. Failing to do so can invalidate insurance.

    • AIt only affects drivers on long journeys, and not on short local runs
    • BCan impair concentration, reaction time, and decision-making
    • CA marginal effect
    • DDrivers should push through stress and finish the shift anyway

    • BIt should be kept hidden from the DVLA so that no restrictions can be imposed
    • CIt is only relevant if the condition first arose within the last twelve months

    • BEvery 2 years from the date of first issue
    • COnce a year from the very first licence

    • AIncrease speed to stay alert
    • BPinch yourself to stay awake
    • CPull over safely, rest, or change drivers

    • AOnly if hospitalised
    • BMinor colds
    • CEvery condition is picked up by the medical examination, so notification is unnecessary

    • BPoor diet can affect energy, concentration, and reaction time
    • CDiet doesn't affect driving ability
