The Driver Knowledge Test Questions Everyone Gets Wrong

Give-way rules that catch almost everyone

These eight are pulled directly from the same question banks the real state tests draw on, not paraphrased or simplified — the wording, the options and the explanations below are what a real learner would actually see.

Start with a sign everyone thinks they already understand: “The difference between a STOP sign and a GIVE WAY sign is:” The correct answer isn’t about priority at all — both signs create exactly the same give-way duty. The only difference is that a STOP sign forces a complete stop even if the road is empty, while a GIVE WAY sign only requires you to stop if there’s a reason to.

Next, the intersection where two GIVE WAY signs face each other: “Two vehicles face each other across an intersection, both on roads with GIVE WAY signs. One goes straight, the other turns right. Who goes first?” The vehicle going straight goes first — the right-turning driver gives way, exactly as if there were no signs at all. Matching sign conditions don’t cancel the normal turning rule.

Turning right: the rule that never changes

The same logic trips people up at unmarked crossroads: you’re “turning right and an oncoming car is going straight.” You must give way to the oncoming car before you turn. Arriving first, or arriving from the wider road, changes nothing — a right turn always gives way to a vehicle coming straight through or turning left.

It applies just as strictly when the oncoming vehicle is a bicycle: “Turning right at an intersection, an oncoming cyclist is riding straight through. You must” give way to the cyclist just as you would to an oncoming car. Bicycles are legally vehicles, and a right-turning driver who assumes a cyclist will yield because they’re slower or smaller is simply wrong — and it’s a favourite exam trap for exactly that reason.

Merging, driveways and who actually has priority

Zip merges confuse people who’ve never had the rule spelled out: “Two lanes merge into one and the lane markings END before the merge. Who gives way?” The vehicle that’s behind gives way to whatever is ahead of it in either lane — not the left lane, not the right lane, and not whoever is bigger. Treat it like a zip: one car at a time, in order.

And at driveways: “You are driving along a road and a car is waiting to pull out of a driveway. Who gives way?” The driver leaving the driveway gives way to you, full stop. Every vehicle entering a road from a driveway or private property gives way to everything already on the road, no matter how long they’ve been waiting — even if they’ve been sitting there so long it feels rude not to wave them out.

Speed and alcohol: the numbers people guess at

On speed: “Driving ‘just a few km/h’ over the limit” is still an offence, and it noticeably raises your crash risk — there’s no unwritten 10% tolerance. Examiners include this question because so many learners have absorbed the opposite as folklore from someone else’s car.

On alcohol, the number that surprises most people: “At a blood alcohol level of 0.05, your risk of crashing is about” roughly double that of a driver at zero. It’s not a small step past the legal limit — it’s already a meaningfully more dangerous one, which is why 0.05 is treated as a hard line rather than a rough guideline.

And in NSW specifically, “a special 0.02 blood alcohol limit applies to” bus, taxi and heavy vehicle drivers — a lower bar than the standard 0.05, and one that catches out anyone who assumes the general limit applies to every licence type. If you’re studying for a test outside NSW, check whether your own state runs an equivalent special-category limit before you assume the number doesn’t apply to you.

Why these particular questions keep showing up

None of the eight questions above are obscure trivia — they’re all common driving situations, which is exactly why they’re worth getting right beyond the exam. A give-way mistake at an unmarked crossroads or a misjudged zip merge doesn’t just cost you a mark on test day; it’s the kind of error that causes real crashes on real roads. Treat these as the short list of rules to genuinely understand, not just memorise, before you book.
