Selected questions from the ranking above. The data records how many answers were wrong, not why, so the readings below are ours — our interpretation of the wording against the rule. The percentages come from the same set of 7,846,823 answers; open a question for its full text, its options and the official explanation.

The trap: The sign tells you which side the subordinate road joins from. It says nothing about whether that road is one-way. The question slips that extra property into the wording and counts on you reading it as part of the warning.

The trap: The rule hangs on a lane count: outside a built-up area a two-way road needs marked lanes and at least three of them in your direction. Two lanes your way look like enough, and two lanes are what the photo shows.

The trap: Folk wisdom says ABS shortens the braking distance. What the system does is keep the car steerable while you brake — the wheels do not lock, so you can still turn. On sand or snow the braking distance can even grow.

The trap: The question quotes 100 m of visibility; the threshold in the regulation is 50 m. The number sits close to the threshold and on the wrong side of it, so flipping the inequality flips your answer.

The trap: The word "always" points at the statutory definition of special caution, which applies in listed situations rather than for the whole night. Quantifiers are worth reading on their own in questions like this.

The spaced-repetition algorithm in Prawo Jazdy GO serves you the questions you get wrong most often first. All 3,518 official questions, exam mode and offline study.
The highest share of wrong answers in this set belongs to "Are you obliged to exercise extreme caution at all times when driving in a residential zone?" — 53% of the answers given to it are wrong. The full ranking of 50 questions sits above on this page. We count answers, not people.
We use the term for questions where, in our reading, a detail of the wording shifts the meaning: a quantifier, a property slipped into the description of a sign, a number sitting just past the threshold in the regulation. Our data does not measure this; the trap section works through a few examples.
The official set for this language has 3,518 questions. 2,120 of them cleared the 1,000-answer threshold and only those enter the ranking — start there, because those are the ones people get wrong most often.
From answers logged in the Prawo Jazdy GO app on Android and iOS. The set covers 7,846,823 answers, captured on 7 August 2026. The percentage shown is the share of wrong answers among all answers given to that question.
The data comes from answers logged in the Prawo Jazdy GO app on Android and iOS. The app records every answer given, together with whether it was correct.
We count answers, not users. One person can answer the same question many times, so the percentage shown is the share of wrong answers among all answers given to that question — not the share of people who got it wrong.
For example, "53% of answers wrong" means that share of all answers to that question were wrong.
We publish only questions with at least 1,000 logged answers. Below that the percentage would swing too much week to week to mean anything.
