Original practice questions written for this site. Not the official question bank. They were written against the current Queensland road rules, with the rule cited under every answer.

  1. Question 1

    What blood alcohol concentration must a Queensland learner licence holder be under while driving?

    • Under 0.08
    • ZeroCorrect answer
    • Under 0.05
    • Under 0.02

    Learner and provisional drivers must have zero blood alcohol. That means no drinking before driving at all.

  2. Question 2

    What is the general blood alcohol limit for an open licence holder?

    • 0.02
    • 0.05Correct answer
    • 0.08
    • 0.10

    Open licence holders must stay under 0.05. Impairment starts well below that figure, so the safest number is still zero.

  3. Question 3

    You drank heavily last night and stopped at 2 am. You need to drive at 8 am. What should you consider?

    • You are safe as long as you feel fine
    • A big breakfast will bring your reading down
    • Sleep clears alcohol, so you are certain to be under the limit
    • Alcohol may still be in your system, and as a learner you must be at zeroCorrect answer

    The body clears alcohol slowly, and morning after readings are common. Feeling normal is not evidence of a zero reading.

  4. Question 4

    Which of these is an early warning sign of driver fatigue?

    • Drifting in the lane, yawning and missing signsCorrect answer
    • Wanting to change the radio station
    • Gripping the wheel more tightly
    • Feeling too warm

    Those signs mean your attention is already failing. Pull over somewhere safe and sleep before you continue.

  5. Question 5

    How can you reduce the risk of fatigue on a long trip?

    • Drive through the night when roads are quiet
    • Plan rest breaks roughly every two hours and share the driving if you canCorrect answer
    • Keep the cabin very warm
    • Skip meals so you stay alert

    Regular breaks, a proper sleep beforehand and avoiding the small hours are the three things that actually work.

  6. Question 6

    You have been prescribed a medicine that warns it may cause drowsiness. What should you do before driving?

    • Take a smaller dose and drive as usual
    • Drive only on quiet roads
    • Drive and see how you feel after a few kilometres
    • Read the label and ask your doctor or pharmacist whether it is safe to driveCorrect answer

    Prescription and over the counter medicines can slow reactions and blur vision. Driving while impaired by any drug is an offence.

    Rule cited: Your Keys to Driving in Queensland handbook, topic: drugs and driving

  7. Question 7

    What should you know about roadside drug testing in Queensland?

    • Police can test drivers at the roadside for certain drugs, and having a relevant drug present is an offenceCorrect answer
    • Only drivers involved in a crash can be tested
    • Testing only happens at night
    • Testing applies only to drivers over 25

    Roadside saliva tests can be given to any driver. Unlike alcohol, there is no allowance for a small amount of a relevant drug.

    Rule cited: Your Keys to Driving in Queensland handbook, topic: drugs and driving

  8. Question 8

    You have been drinking and want to lower your blood alcohol before driving. What actually works?

    • Strong coffee
    • Time, and nothing elseCorrect answer
    • A cold shower and fresh air
    • A large meal before you leave

    Coffee, food and cold water may make you feel more awake, but the alcohol level in your blood only falls as your body processes it.

    Rule cited: Your Keys to Driving in Queensland handbook, topic: alcohol and driving

  9. Question 9

    What happens when a driver has had alcohol and is also tired or has taken medication?

    • The tiredness cancels out the alcohol
    • The alcohol keeps the driver alert for longer
    • The effects add together and impair the driver more than either would aloneCorrect answer
    • There is no effect while the reading stays under the limit

    Combining alcohol with fatigue or with some medicines multiplies the loss of judgement and reaction time.

    Rule cited: Your Keys to Driving in Queensland handbook, topic: alcohol and driving

  10. Question 10

    What is a microsleep?

    • A short nap taken deliberately at a rest stop
    • A moment of blurred vision caused by glare
    • A daydream that a driver can snap out of at will
    • A brief loss of awareness lasting a few seconds that a tired driver may not even noticeCorrect answer

    At highway speed a few seconds covers a long stretch of road with nobody steering. The only fix for fatigue is sleep.
