✍️ Sample CPC Questions & Answers
1. What is the legal requirement for a professional driver's eyesight standard?
Group 2 (professional) licence holders must meet stricter DVLA visual acuity standards: 6/7.5 in the better eye, 6/60 in the worse, with no conditions affecting visual fields.
2. What is the purpose of the daily vehicle check (DVC) record book?
The DVC book provides a formal record that required checks were made; it must be available for DVSA inspection and demonstrates the operator's compliance with vehicle roadworthiness obligations.
3. Which gear-changing practice promotes fuel efficiency?
Changing up early and block shifting keeps the engine in its fuel-efficient low-rev range; high revs in a lower gear burn significantly more fuel for the same vehicle speed.
4. In ADR dangerous goods transport, what do orange hazard panels (plates) on the front and rear of the vehicle indicate?
Orange ADR hazard panels carry the Hazard Identification Number (HIN) on top and the UN product number on the bottom, enabling emergency services to immediately identify the substance carried.
5. What happens if a driver's digital tachograph card is lost or stolen?
If a card is lost or stolen, the driver must apply for a replacement within 7 calendar days and can continue driving without the card for a maximum of 15 calendar days, provided they can produce printouts from the tachograph at the start and end of each journey.
6. What does an amber warning light on an HGV dashboard typically indicate?
Amber warning lights indicate an advisory condition or developing fault that needs attention soon but may not require immediate stopping. Red warning lights indicate critical failures requiring immediate action.
