What this page is, and what it is not
It is not a measured list. We do not publish "the question 82% of learners get wrong", because we have not measured that and neither, as far as we can tell, has anyone else who says it.
What we can describe with confidence is how hard questions are built, because we write them. A hard question is almost never an obscure fact. It is a distinction where two answers are both reasonable, where one of them matches what a sensible driver would do, and where the law says the other one. Get the distinction and the question is easy. Miss it and no amount of revision helps, because you will keep meeting it in new clothes.
There are roughly five of those distinctions, and they account for a large share of the questions that feel unfair. Each one below comes with the provision it rests on, so you can check us.
The five distinctions
Each row is a pair of answers that both look right. The third column is the thing that separates them.
| The pair | What separates them | Where it comes from |
|---|---|---|
| A symbol in a red ring, and the same symbol on a blue disc | A red ring prohibits; a blue disc commands or reserves. Identical picture, opposite instruction | The sign classes and colour conventions in the official signs manual, and the prescribed meanings in Schedule 1 |
| Order of stopping, and yield to the vehicle on your right | The four-way stop rule is order of stopping. Yield-to-the-right governs a junction where traffic moves around a traffic island | The prescribed meaning of sign R1.4, and regulation 301 |
| The road's speed limit, and the vehicle's speed limit | Where both apply, the lower governs. A class limit is a ceiling on that vehicle, not permission to use it anywhere | Regulations 292 and 293(1), and section 59 of the Act |
| A solid line you may cross, and one you may not | Both have exceptions and both lists are closed. A single no-overtaking line has three; a double no-crossing line has one | The no-overtaking and no-crossing markings in the official signs manual |
| A sign on a post, and paint on the road | Nothing separates them for the purpose of the test — markings are road traffic signs and are examined in the same area | Regulation 104(2)(a)(ii), and the markings chapter of the signs manual |
Red ring against blue disc
This is the most productive distinction in the whole signs section, because it generates a pair for almost any symbol you can put inside a circle.
A red ring prohibits whatever is inside it. A blue disc commands or reserves. So the same bicycle means "no bicycles" in the first and "this is for bicycles" in the second, and a number means a maximum in the first and a minimum in the second. If you are reading the picture rather than the border, the two are indistinguishable, and a question that offers you both meanings has already won.
The practical version: read the border before you read the contents. Everything you actually have to do is decided by the border, and the picture only tells you what it applies to.
Order of stopping against yield to the right
Almost every South African driver will tell you that at a four-way stop the car on the right goes first. It is a useful convention and it is not the rule.
The rule is the prescribed meaning of the four-way stop sign: you yield to every vehicle that stopped at another stop line before you and that will cross your path. First to stop, first to go. Yield-to-the-right is how drivers settle a genuine tie, and it has no work to do when the order of arrival is clear.
Yield-to-the-right is a real rule with a real home, which is what makes it so easy to misapply. Regulation 301 puts it at a junction "where vehicular traffic is required to move around a traffic island" — a traffic circle. Asked about a four-way stop, it is simply the wrong provision.
The related trap: a set of traffic lights showing nothing at all. You treat it as a three-way or four-way stop, which means the same order-of-stopping rule applies rather than a free crossing.
Which of two speed limits governs
There are general limits that attach to the road — 60 km/h inside an urban area, 100 km/h outside one on a road that is not a freeway, 120 km/h on a freeway — and there are limits that attach to a class of vehicle, such as 80 km/h for a goods vehicle over 9 000 kg.
A question gives you both and asks what applies. The answer is always the lower one. A goods vehicle limited to 80 may not do 80 in a 60 zone, and on a freeway posted at 120 it is still held to 80. The road's limit does not lift the vehicle's, and the vehicle's does not override the road's.
The reason this catches people is that the class limit is phrased like a permission and read like one. It is a ceiling.
Lines, and the fact that their exceptions are a closed list
This is the distinction where guessing is most reliably punished, because the correct answers are lists and the wrong answers are always reasonable.
A single continuous line between opposing streams of traffic — the no-overtaking line — has exactly three exceptions: to gain direct access to land on the opposite side, to gain access from land onto the opposite side of the roadway, and to pass a stationary obstruction. Each one applies only if it is safe to do so.
Two continuous lines — the no-crossing marking — have exactly one: passing a stationary obstruction, and only if it is safe.
Notice what is not on either list. A slow vehicle is not a stationary obstruction. Being in a hurry is not on the list. A clear road ahead is not on the list. If a question offers you a sensible-sounding reason that is not one of those, that is the wrong answer, and it is wrong for the specific reason that the list is closed.
The broken line is the opposite kind of marking altogether. It is a warning rather than a prohibition — it tells you that traffic on the other side is coming the other way — so you may cross it when it is safe. And where two lines run together, the one on your side is the one that governs you.
Paint counts as signs
The fifth distinction is the one that is not a distinction at all, and it costs people marks for exactly that reason.
Road markings are road traffic signs. They are examined inside the road signs area rather than as a fourth area of their own, which means a learner who worked through the signs on posts and skipped the paint has left a chunk of one scored area unstudied — and it is the area with the strictest rules on it.
If you have been treating markings as scenery, that is the single highest-value hour of revision available to you.
The mistake
Learning the answer instead of the distinction. If you memorise that the answer to one four-way stop question is "the car that stopped first", you have learned one question. If you understand that order of stopping is the rule and yield-to-the-right belongs to circles, you have learned every question built on that pair, including the ones phrased in ways nobody has shown you.
The second is grading yourself on near misses. Picking the right answer without being able to say why the other two are wrong means the distinction is still missing, and the next version of the question will find that out.
Test yourself on the distinctions, not the facts
Thirty free practice questions across the three areas, each with a written explanation that names what the question turns on. The free readiness test is the faster way in: five questions, scored by section, no account needed.
Take the free readiness testCommon questions
What is the most commonly missed learner's licence question?
Nobody can honestly tell you, us included — no usage data for the actual test is published, and we do not have enough of our own to make a claim about a national population. What can be said is which distinctions the hard questions are built on, which is what this page sets out.
Is the four-way stop question really that hard?
It is hard in a specific way: the common driving convention and the rule give different answers. Order of stopping decides it, and yield-to-the-right belongs to a junction where traffic moves around a traffic island.
When may I cross a solid white line?
A single continuous line may be crossed only to reach land on the opposite side, to come out of land onto the opposite side of the roadway, or to pass a stationary obstruction — each one only if it is safe. Two continuous lines allow only the stationary obstruction.
Does a truck's speed limit let it exceed the road's limit?
No, and that is the whole point of the question. Where a road limit and a vehicle-class limit both apply, the lower governs — in both directions.
Are road markings really examined with the signs?
Yes. They are road traffic signs in law and they sit inside the same area of the test, which is why skipping them leaves a hole in an area that is passed on its own.
Are these the questions used at the testing centre?
No. This page describes how hard questions are constructed, not what any particular paper contains. Our own practice questions are written from the Act, its regulations and the official sign chart, each with a citation.
