28 questions

#1Cargo SafetyVerbal

Explain the main safety factors that must be taken into account when loading the vehicle.

The load must be evenly distributed along the entire length of the vehicle so that it does not affect effective vehicle handling. Any cargo must be transported in a way that poses no danger to other road users. Cargo must be safely positioned within the vehicle's dimensions and maximum permissible weight. Furthermore, the secured load must not shift or fall off during turns or braking.

#2ReflectorsVerbal

Explain how proper operation of retro-reflectors is checked.

Make sure all retro-reflectors are fitted, clean, and functioning (not cracked or broken).

#3Windscreen and WindowsVerbal

Explain how to check the condition of the windscreen and windows.

The windscreen and windows must be clean, transparent, and free of defects. Nothing should be attached that restricts the field of vision.

#4Mudguards (Wings)Verbal

Explain how proper condition of mudguards (fenders) is checked on the vehicle.

The condition of mudguards (fenders) is checked visually as part of the daily inspection.

#5Tire Air PressureVerbal

Explain how to check tires to ensure they have the recommended air pressure.

To check tire pressure, follow manufacturer instructions using appropriate tools — dashboard indicators and/or a pressure gauge. Pressure must be checked when tires are cold.

#6Tire Tread DepthVerbal

Explain how to check tires to ensure sufficient tread depth.

Use manufacturer instructions and a depth gauge or ruler to measure tread depth at the most worn point. Without wear indicators, tread depth must not be less than 1.0 mm for C/C1 categories, and not less than 2.0 mm for D/D1 categories.

#7General Tire ConditionVerbal

Explain how to check tires to ensure overall safe condition.

Tires are inspected visually: they must match vehicle specification and show no signs of low pressure, tread separation, mechanical damage, or excessive wear.

#8Windscreen WasherVerbal

Explain how the windshield washer condition is checked.

The windshield washer must be operational and its wiper blades must be in good condition.

#9Vehicle BodyworkVerbal

Explain how vehicle body condition is checked.

As part of the daily check, ensure the body is fit for operation without major defects. There must be no loose parts or devices on the body that could pose a danger to other road users.

#10Brake System Air PressureVerbal

Explain how to check for proper air pressure in the brake system.

Ensure the dashboard gauge shows proper air pressure, the warning light is off, and the acoustic warning alarm is silent.

#11Engine Oil LevelVerbal

Explain how to check for the required engine oil level.

With the vehicle on flat ground and engine off, remove the oil dipstick, wipe it clean, reinsert it, and pull it out again. The oil level mark must lie between MIN and MAX notches.

#12Wheel NutsVerbal

Explain how to check that wheel nuts are properly tightened.

Visually inspect whether any wheel nuts are loose and ensure wheel nut indicators (if present) are in the correct alignment.

#13Suspension SystemVerbal

Explain how vehicle suspension system condition is checked.

During daily checks, inspect the suspension system for any obvious signs of wear or damage.

#14Brake LightsVerbal

Explain how to check proper operation of brake lights.

Brake lights (main and supplementary) must illuminate upon pressing the brake pedal and stay continuously lit while depressed.

#15CoolantVerbal

Explain how to check for required engine coolant level.

With cold, switched-off engine, coolant level inside the expansion tank must be between MIN and MAX marks.

#16Headlights & Lights ConditionVerbal

Explain how to check headlight and marker light functionality.

Turn ignition key, switch on position lights and check dashboard indicators, then visually inspect (or ask a third party) light operation, cleanliness and condition. Repeat for dipped and main beam headlights. A wall in front can also be used for reflection.

#17Lifting Mechanism / RampVerbal

Explain how to use the lifting mechanism of the given vehicle (e.g., wheelchair ramp or tail lift).

The driver candidate must briefly explain the principle of proper and safe operation of the lifting mechanism fitted to the respective vehicle.

#18Power SteeringVerbal

Explain how to check power steering operation.

After starting the engine, required steering force reduces significantly. Steering wheel must not rotate spontaneously when wheels are straight. Steering force variation across full turn range should be smooth without jerks, vibration or noise.

#19Direction IndicatorsVerbal

Explain how to check direction indicators.

Switch ignition on, activate left and right turn signals, verify panel indicators, then visually inspect (or ask a third party) their flashing operation, cleanliness and glass integrity.

#20Washer Fluid Level (Theoretical)Verbal

Explain how to check washer fluid level.

Check dashboard indicator after turning ignition on. If no indicator exists, inspect according to vehicle user manual.

#21Dashboard (Before Engine Start)Verbal

Explain what needs to be checked on the instrument panel before starting the engine.

Check the operation of all control gauges and warning indicators on the instrument panel before ignition.

#22Dashboard (After Engine Start)Verbal

Explain what indicators on the instrument panel must be checked after starting the engine.

Verify that all control gauges and warning indicators on the instrument panel show normal operational parameters.

#23Washer Reservoir (Practical)Practical

Show where the windscreen washer reservoir is located.

The candidate must physically point out the location of the washer fluid reservoir in the test vehicle.

#24Door Closure Check (Practical)Practical

Demonstrate how to check that all doors, including cargo compartment doors, are closed.

The driver candidate must close all doors and set the cargo door locking lever to the recommended safety position.

#25Air System Leak Check (Practical)Practical

Demonstrate how to check for air system leaks.

The candidate must build up pressure in air reservoirs, check the gauge on the dashboard to see if pressure drops, walk around the vehicle, and listen carefully for any audible air leaks.

#26Coolant Reservoir (Practical)Practical

Show where to check engine coolant level.

The candidate must physically show the engine coolant expansion tank.

#27Tachograph Card / Disk ReplacementPractical

Demonstrate/explain how to replace the record sheet or operate the digital tachograph.

To start shift mode on a digital tachograph, insert the driver card into slot 1, navigate the menu to select starting location (country), confirm with 'OK', and switch rest mode to work/drive mode to open the working day. Upon shift completion, stop the vehicle, turn off the engine (automatically switching mode to rest), select ending location (country), confirm with 'OK', and close the working day. For multi-driver crews, insert the second driver's card into slot 2.

#28Engine Oil Dipstick (Practical)Practical

Show where engine oil level is checked.

The candidate must physically point to the engine oil dipstick handle.
