Frequently asked questions about road safety on the B licence
- How many road safety questions are in the B licence question bank?
- Our exam-style question bank includes 148 road safety questions for the B licence. Each comes with the correct answer and explanation.
- How should I study road safety for the B licence exam?
- The B test has 30 questions. Use this bank to practise road safety with explanations, and combine topic review with full mock exams.
- What are the most common road safety mistakes?
- Three typical causes: 1) misreading prompts with decisive keywords ("always", "never", "except", "only", "at least") — they flip the correct answer; 2) switching correct answers in the final review due to self-induced doubt; 3) studying only by topic without full simulations, which penalises block-switching speed.
- How should I practise road safety to prepare for the B licence?
- Alternate three modes: first study the full topic syllabus; then practise the 148 exam-style road safety questions until you understand the logic of each; finally launch full B-licence simulations (30 questions, max 3 wrong) to train block-switching under pressure.
