All 10 original practice questions on this topic, with the correct answer marked and the reason under each one.
Where these questions come from
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. Department of Transport and Main Roads does not publish the QLD PrepL question bank, so nothing on this page is the wording you will meet in the sitting.

Question 1
What blood alcohol concentration must a Queensland learner licence holder be under while driving?
Learner and provisional drivers must have zero blood alcohol. That means no drinking before driving at all.
Rule cited: Your Keys to Driving in Queensland handbook, topic: alcohol and driving
Question 2
What is the general blood alcohol limit for an open licence holder?
Open licence holders must stay under 0.05. Impairment starts well below that figure, so the safest number is still zero.
Rule cited: Your Keys to Driving in Queensland handbook, topic: alcohol and driving
Question 3
You drank heavily last night and stopped at 2 am. You need to drive at 8 am. What should you consider?
The body clears alcohol slowly, and morning after readings are common. Feeling normal is not evidence of a zero reading.
Rule cited: Your Keys to Driving in Queensland handbook, topic: alcohol and driving
Question 4
Which of these is an early warning sign of driver fatigue?
Those signs mean your attention is already failing. Pull over somewhere safe and sleep before you continue.
Rule cited: Your Keys to Driving in Queensland handbook, topic: fatigue
Question 5
How can you reduce the risk of fatigue on a long trip?
Regular breaks, a proper sleep beforehand and avoiding the small hours are the three things that actually work.
Rule cited: Your Keys to Driving in Queensland handbook, topic: fatigue
Question 6
You have been prescribed a medicine that warns it may cause drowsiness. What should you do before driving?
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
Question 7
What should you know about roadside drug testing in Queensland?
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
Question 8
You have been drinking and want to lower your blood alcohol before driving. What actually works?
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
Question 9
What happens when a driver has had alcohol and is also tired or has taken medication?
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
Question 10
What is a microsleep?
At highway speed a few seconds covers a long stretch of road with nobody steering. The only fix for fatigue is sleep.
