How to pass the B licence questions
This bank holds 5,378 exam-style DGT questions updated for 2026 for the B licence, organised in 39 topics. Each question includes the options, the correct answer and an explanation so you understand why and don't repeat the mistake.
The most effective strategy is to alternate three study modes: reading the syllabus, taking simulations under real conditions (30 questions, 30 minutes, max 3 errors) and reviewing the questions you got wrong. Failed questions enter the smart-review queue until you master them.
The questions update whenever the DGT changes the syllabus. The main 2026 updates concern new rules on personal mobility vehicles (VMPs), urban speed limits and the mandatory V-16 emergency light replacing warning triangles.
Frequently asked questions about the B licence
- How many questions does the B licence theory exam have?
- The B licence theory exam has 30 multiple-choice questions, lasts 30 minutes and allows a maximum of 3 wrong answers to pass. The questions in this bank follow that format, but it is not the official DGT bank.
- What is the minimum age for the B licence in Spain?
- The minimum age for the Spanish B licence is 18. You can start studying and enrol at a driving school earlier, but the official exam only takes place once you reach this age.
