Common mistakes in the CSDD theory exam

Most people don't fail the theory exam because they don't know the rules — they fail on carelessness and rushing. Here are the typical mistakes that cost points, and how to avoid them.

Reading the question carelessly

Keywords decide everything: 'prohibited' vs 'allowed', 'all' vs 'except'. One missed word flips the correct answer. Read the whole question to the end, not diagonally.

Confusing priority signs

Priority road vs minor road, 'Give way' vs STOP — easy to mix up under time pressure. First work out who is on the priority road, then pick your answer.

Mistakes at junctions and roundabouts

Unregulated junctions and roundabouts cause most of the disputed cases. Keep a simple right-of-way rule in mind and check it against the signs and markings in every question.

Speed and built-up areas

Limits in a built-up area, outside it, and in a residential zone are the most commonly confused. Check the current figures in the official CSDD (the Road Traffic Safety Directorate, Ceļu satiksmes drošības direkcija) materials — the rules are updated from time to time.

Rushing and guessing

It isn't a speed test. Read every answer option to the end — the 'almost right' one often comes first, the exact one lower down.

A mini-scenario from Roman: three moments where beginners and experienced drivers alike slip up most often. Check if any sound familiar.

1 / 3

Morning, you're driving past a school. A knot of kids with backpacks stands at the kerb, no traffic lights. What's your speed?

Real-world situations

The question asks 'Whom MUST you give way to?' You read 'give way' and pick the first plausible option.

Pay attention to the exact wording and all the options: the correct answer is often 'to all of the above' or 'to none'. Words like 'must', 'except', 'all' change the answer.

The diagram shows an equal-priority junction with a car on your right. You're rushing and choose 'I go first'.

At an equal-priority junction you give way to the car on the right (paragraph 133). Work out the priority from the signs first, then answer.

It's a question about the speed limit in a residential zone, and out of habit you answer '50'.

In a residential zone and courtyards it's 20 km/h, not 50. Keep them separate: built-up area — 50, outside it — 90, residential zone — 20.

Key takeaways

The words 'except', 'all', 'must' often change the correct answer.
Read every option: the exact answer often isn't the first one.
You get 30 minutes for 30 questions — there's time to think, no need to rush.
