The most failed DGT exam questions (and how to bulletproof them) ⚠️
Quick answer: Theory fails concentrate in a few topics: speed and its exceptions (overtaking, single-lane urban roads), priority at roundabouts and junctions, overtaking (when and where it's banned), alcohol limits for novices, safety and stopping distances, look-alike signs and rule changes — in 2026, the V-16 beacon. They're failed not because they're hard, but because the DGT asks the exception, not the rule.

The 7 trap topics (table)
| Topic | Why it's failed |
|---|---|
| Speed | People know the general limit, not the exception (e.g. while overtaking or on single-lane urban roads) |
| Roundabouts and priority | «Priority for those inside» gets confused with lane and exit cases |
| Overtaking | The specific banned spots: crests, junctions, pedestrian crossings |
| Alcohol and drugs | Novice and professional limits, not the general one |
| Distances | Safety vs stopping vs reaction — three concepts that blur |
| Look-alike signs | End of prohibition vs end of restriction; R- vs P-; square vs round blue signs |
| 2026 changes | The V-16, e-scooters and recent updates — old material doesn't include them |
The pattern: the DGT asks the exception
The official bank rarely asks «what's the motorway limit?»; it asks «can that limit be exceeded and when?». That's why studying general rules plateaus you at 80–85% — the risk zone from which 4 mistakes sink you. Bulletproofing these topics means studying each rule together with its exceptions and practising with questions that attack them directly.
How to bulletproof them in a week
- Take 2 official-mode mocks and note the topic of every mistake.
- Review theory only for those topics, focusing on exceptions and figures.
- Drill per-topic tests until you chain error-free sessions.
- Return to the full mock: the improvement is immediate and measurable.

Frequently asked questions
Which questions are failed most in the DGT theory?
Speed exceptions, roundabouts, overtaking, novice alcohol limits, distances, look-alike signs and changes like the V-16.
Why are they failed if they're not hard?
Because the exam asks the exception, not the rule — and much circulating material is outdated.
How do I find my weak topics?
Two official mocks + classify mistakes by topic — per-topic statistics do it automatically.
Will trap questions definitely appear in my exam?
Nothing is guaranteed, but these topics dominate the bank — the probability is very high.
