Question 1

How does alcohol affect your ability to drive?

Accepted Answer

It slows your reaction time and impairs your judgment

Answer

Alcohol impairs the brain functions needed for safe driving — reaction time slows, judgment deteriorates, and coordination is reduced — even before a driver feels obviously drunk.

Question 2

In NSW, roadside oral fluid (drug) testing detects the presence of:

Accepted Answer

Cannabis, methamphetamine (speed/ice), and MDMA (ecstasy)

Answer

NSW Police use oral fluid swabs to test for three specific drug types at the roadside: cannabis (THC), methamphetamine, and MDMA. A positive result leads to a laboratory confirmation test.

Question 3

A full licence holder in NSW records a BAC of 0.07. Which offence category does this fall into?

Accepted Answer

Low range prescribed concentration of alcohol (PCA)

Answer

A BAC of 0.05–0.079 is classified as a Low Range PCA offence in NSW. The legal limit is under 0.05, so 0.07 is above the limit and carries licence suspension, a fine, and demerit points.

Question 4

Which of the following factors does NOT affect how quickly alcohol is absorbed into your bloodstream?

Accepted Answer

The colour of your eyes

Answer

Eye colour has no effect on alcohol absorption. Food in the stomach slows absorption, lower body weight means a higher BAC for the same amount, and women typically absorb alcohol faster than men due to body composition differences.

Question 5

Driving after combining cannabis with alcohol, compared to using either substance alone, will:

Accepted Answer

Significantly increase your crash risk beyond either substance alone

Answer

Cannabis and alcohol together produce a combined (synergistic) impairing effect that is significantly greater than either drug on its own, dramatically increasing the risk of a serious crash.
