How to pass the DGT theory test 2026 first time

The B-licence theory exam is computer-based and taken at an official DGT centre. You identify with DNI or NIE, you are assigned a workstation and the test starts automatically. There is no examiner in front of you: you answer on screen with three options per question and a single correct mark. You can skip questions, flag them for review and come back before submitting.

There are 30 questions with 30 minutes total. You may fail at most 3 questions — at the fourth wrong answer the exam is failed. You receive the result the same day, normally the next day on the DGT online portal. If you pass, the theory is valid for 2 years from the exam date for booking the practical test.

Week 1: read the full syllabus by topic (signage, priority, speed, general rules) without doing tests yet. The goal is to understand the logic, not memorise. Spend 30–45 minutes a day. By the end of the week you'll have covered the main blocks and built a mental map of what's examined and how topics connect.

Weeks 2–3: combine topic-based tests with a full simulation every 2–3 days. After each simulation, review your mistakes one by one and understand why the correct option is correct — reading the answer isn't enough. If a topic gives you more than 3 wrong per simulation, go back to the syllabus before doing more tests on it.

Weeks 4–6 (if you need them): only full simulations and error review. Start timing yourself: 30 questions in 30 minutes with no pauses. When you hit 5 consecutive simulations with 1 wrong or fewer, book the real exam. If you can't reach that level, keep practising — booking too early greatly raises the chance of failing and wasting money.

The 30-question simulation is the most important format because it replicates real exam conditions: mixed topics, time pressure, no hints. Do it timed and without consulting anything. It is the tool that tells you whether you are ready. At minimum 15 simulations before the real exam; in first-attempt-pass candidates the average is closer to 20–25.

Topic tests are for reinforcing specific weak points. If you fail 4 signage questions in a simulation, do two signage-only tests before the next simulation. Don't overuse them: studying only by topic without full simulations leaves the time-pressure muscle untrained, and time pressure is one of the biggest reasons people fail.

10-question sprints are ideal for short days or as a warm-up before a simulation. They don't replace the full simulation but they keep the habit and reinforce error review. Use them when you only have 10–15 minutes available.

Vertical and horizontal signage: the largest block with the most nuance. The typical error is confusing similar signs — warning vs mandatory — or missing the keyword in the prompt ("always", "never", "except"). Give it dedicated review in the final days before the exam.

Priority and speed: two blocks where the difference between pass and fail is usually in the numeric details. Memorise the maximum speeds per road type and vehicle category, and review the priority rules at unsignalled intersections (right has priority, vehicles in the roundabout, priority vehicles).

Alcohol, drugs and medical: a topic with numeric traps (breath alcohol limits, blood levels, penalties). Learn the exact limits — 0.15 mg/l, 0.25 mg/l, 0.3 mg/l, 0.5 g/l — and which driver category each applies to (general, professional, novice).

Bring original DNI or NIE (no photocopy) and, if requested, proof of paid fee. Arrive 30 minutes before the scheduled time: if you are late you are not admitted and you lose the slot. Some centres have lockers for phone and bag — you cannot enter with a phone or study material — but not all, so travel light.

During the exam, read each prompt twice before marking — traps are usually in the prompt keyword, not the options. If you are unsure, flag the question for review and move on: order doesn't count and saving questions for the end reduces head-noise. Reserve the last 5 minutes to review flagged questions. Don't submit early: do at least one full pass before submitting.

Failing isn't the end of the road: 35% of candidates fail the first sitting and end up passing on the next. First, request the official correction on the DGT portal — it shows exactly which questions you got wrong. That's gold data: identify the 2–3 weakest topics and focus the next study block on them.

The fee you already paid covers two theory attempts — you don't pay again for the second sitting. Book with 1–2 weeks buffer to study more, not sooner. While you wait, do daily full simulations until you have 5 in a row with 1 wrong or fewer. Only then book the second attempt.
