How Is It Different from the Car Theory Test?
The Truck & Bus theory test (also called the LGV/PCV theory test) has a separate question bank from the Car & Motorcycle test. While many road safety principles are the same, the Truck & Bus test includes additional topics specific to large and heavy vehicles.
Key Differences
- Separate question bank: 401 dedicated questions
- Higher fee: €72 (vs €45 for the car test)
- Same format: 40 questions, 45 minutes, 35 to pass
- Additional topics: Vehicle-specific questions about air brakes, tachographs, load securing, and driver hours
Topics Covered
Control of Vehicle (LGV/PCV)
Questions specific to handling large vehicles:
- Air brake systems and components
- Diff-lock operation
- Coupling and uncoupling trailers
- Fifth wheel maintenance
- Power steering systems
- Speed limiters
Legal Matters (LGV/PCV)
- Driver hours and rest periods (EU regulations)
- Tachograph requirements and operation
- Maximum Authorised Mass (MAM) for different vehicle configurations
- Licence categories (C1, C, D1, D, CE, DE)
- CPC (Certificate of Professional Competence) requirements
Managing Risk (LGV/PCV)
- Blind spots on large vehicles
- Turning at junctions with long vehicles
- Overtaking considerations for large vehicles
- Stopping distances for heavy vehicles
Safe and Socially Responsible Driving (LGV/PCV)
- Load distribution and securing
- Effects of high winds on large vehicles
- Driving with passengers (bus-specific)
- Environmental considerations
- Fatigue management for professional drivers
Technical Matters (LGV/PCV)
- Air brake system checks
- Suspension types (air, road-friendly)
- Axle weights and configurations
- Vehicle dimensions and maximum lengths
- Tyre requirements for heavy vehicles
Study tip: If you already hold a car licence, many of the general road safety questions will be familiar. Focus your extra study time on the vehicle-specific topics like air brakes, tachographs, driver hours regulations, and load securing.
Requirements for a Truck/Bus Learner Permit
- Pass the Truck & Bus theory test (€72)
- Medical report (mandatory for Category C and D)
- Hold a full Category B (car) licence — you must already have your full car licence
- Visit an NDLS centre with all documents (€35 fee)
Important: You cannot apply for a Category C or D learner permit unless you already hold a full Category B driving licence.
