(1)How to pass the B licence questions
This bank holds 138 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.
