Why do so many candidates fail the DGT Permiso B theory exam?

Official DGT data shows failure rates hovering around 50–55% on the first sitting. Most mistakes occur in recent regulatory reforms (RD 518/2026, V-16 connected beacon, 20 km/h urban zones) and legacy habits (such as the abolished 20 km/h overtaking margin).

Are the questions in Metruta identical to the official DGT exam?

Yes. Metruta features over 6,450 questions mirroring the official computerized format used at DGT examination centers (30 multiple-choice questions, maximum 3 allowed mistakes, 30-minute timer).
