The free 30-question mock: train with the exam's exact format 📝
Quick answer: Spain's official B-licence theory exam is 30 multiple-choice questions with 3 options, 30 minutes, and a maximum of 3 mistakes to pass (4 mistakes = fail). Training with that exact format — not 10-question bursts — is what truly prepares you: TraficoTest offers 4 free 30-question exams, timed, with explained corrections and no registration.
There's a vast gap between «knowing the theory» and passing a 30-question exam against the clock: time management, question-25 fatigue and trick wording only get trained by simulating the real format. This guide explains the official test in detail and how to squeeze the free mocks.
The official format, in detail 📊
| Element | Detail |
|---|---|
| Questions | 30 multiple-choice, 3 options, one correct |
| Time | 30 minutes (a minute per question on average — plenty unless you stall) |
| Mistakes allowed | Maximum 3; the fourth means a fail |
| Content | The full syllabus: rules, signs, road safety, basic mechanics, first aid |
| Languages | Spanish and others, English included |
| Result | Usually online within 24-48 h |
Strategy for the 30 minutes ⏱️
- Fast first pass: answer what you know cold (typically 70-80 %) without burning time on doubts.
- Second pass for the flagged ones: re-read hunting the absolutes («always», «never», «only») — that's where traps live.
- Never leave blanks: a blank counts like a mistake, so a reasoned guess always buys hope.
- Keep 3 final minutes to review flagged answers — and resist gut-feeling changes: switch only with a concrete reason.
Using the free mocks to arrive ready 🎯
The 4 free TraficoTest exams replicate the format to the millimetre: 30 questions, a timer and instant correction with each mistake explained. The method that works: one full mock a day, immediate mistake review and a weekly glance at per-topic statistics — once you chain several mocks at 0–2 mistakes, you're statistically ready to book. With full access, the pass probability computed from your results turns the hunch into a number.
A nuance many learn late: the exam's most-failed questions cluster in a few topics — speeds, alcohol, priorities and signs. Give them dedicated sessions and the whole mock rises by itself.
