Category C1, C, D1, D
35. Tell what actions you will perform with the tachograph before starting work and after finishing it.
Before starting work, the driver connects to the tachograph, selects the "Start work" mode and checks whether the device is working properly. At the end of the work, he selects the "Finish the work" mode, disconnects from the tachograph and can check the work time report, making sure that all the data is correct.
36. Show or tell how you would check the air system for leaks.
With the engine off, observe the pressure drop in the system. With the engine off, support the wheels, release the parking brake, and with the service brake applied, watch for a pressure drop of less than 3 psi (0.2 atm) per minute in a car or 4 psi (0.3 atm) per minute in a vehicle combination. Listen for a hissing sound as you walk around the car.
37. Tell what must be taken into account when loading a vehicle.
The weight and dimensions of the load must not exceed the permitted values. Distribute the load according to the permissible axle loads.
Check if the pallets are securely wrapped with film. Arrange the load symmetrically, load heavier loads at the bottom, securely fasten them.
The load must not obstruct visibility, not fall apart, not pollute the environment.
38. Tell how you will check the condition of lights and reflectors.
When I turn on the ignition or start the car on the dashboard, the corresponding indicator lights (side, low, high, front fog or rear fog) will come on along with the lights, so I can check the operation of these lights.
A warning light on the dashboard will notify you of a broken or burned-out headlight bulb (if such a function is provided in the car's system).
I will check the rest of the lights visually (number plate light, stop lights, reverse lights).
Another option is to turn on the lights one after the other and visually check that the lights are on.
When you go around the car, check whether the reflectors are clean, not cracked, and reflect the light properly.
39. Tell me how you will check the condition of the glasses.
When walking around the car, check whether the windows are clean, not cracked, not scratched, and the glass units are not wet.
40. Tell me how you will check the condition of the fenders.
When walking around the car, check whether the mudguards are not broken or torn.
41. Tell me how you will check if the air pressure in the tires is enough to drive safely.
Check the air pressure with a manometer. By comparing the readings with the value recommended by the manufacturer, you will know if the air pressure in the tires is sufficient for safe driving.
42. Tell how you will check whether the tire tread depth is sufficient for safe driving.
You can measure the depth of the tire tread with a caliper or a special tool.
43. Tell how you will check whether the general condition of the tires is suitable for safe driving.
Tires should be inspected for cracks, lumps, cuts or other damage. The depth of the tread pattern must correspond to the permissible, the wear of the tire must be uniform.
44. Tell me how you will check the condition of the windshield wipers.
After spraying the liquid, the wiper should clean the glass evenly and cleanly. The squeegee must not wobble on the axle, this would indicate a worn attachment point.
45. Tell me how you will check whether the condition of the body is suitable for safe driving.
When you walk around the car, check whether the body is rusted, rotted, broken, or if the screws are not loose.
46. Show or tell how you would check whether the air pressure in the brake system is suitable for safe driving.
Check the readings of the pressure gauge of the car that has been started. Normally, system pressure should be around 125 psi (8.5 atmospheres). With the engine off, you'll support the wheels, release the parking brake, and apply the service brake to see if the pressure drops faster than 3 psi (0.2 atm) per minute in a car or 4 psi (0.3 atm) per minute in a vehicle combination.
Bleed the system with the ignition on and the brake pedal depressed and watch for a warning signal (light) when the pressure drops to 60 psi (4 atm).
As you continue to bleed, watch for the parking brake valve closing when the pressure drops to 40 psi (2.7 atm).
47. Tell me how you will check whether there is a sufficient number of fire extinguishers in the car and whether they meet the requirements.
I will check that there is a sufficient number of fire extinguishers in the car according to legal requirements, which may vary depending on the country or region. I will then check the condition of each fire extinguisher, making sure they are properly installed and accessible, that they are not expired, and that they meet the minimum capacity and performance requirements. If I notice any deficiencies or inconsistencies, I will make sure that the necessary changes or additions are made to ensure the safe and legal protection of the car against fire.
48. Tell how you will determine whether the oil level in the engine is sufficient.
The car is parked on a level ground, the oil is checked when the engine is cold. Pull out the oil dipstick and after wiping it with a rag, insert it back into its tube as far as it will go and pull it out again.
The oil level should be between the MIN and MAX marks.
49. Tell how you will check whether the wheel nuts are securely tightened.
When driving around the car, check the wheel nuts with a wrench.
50. Tell me how you would check the position and condition of the air suspension.
The condition of the suspension is periodically checked in the service. Visually check whether the springs or hinges are not broken, the airbags are not damaged. When driving, you should pay attention to whether there are any extraneous sounds. 
51. Tell how you will check if the brake light signals work.
Get a helper to check that the brake lights work when you press the brake pedal.
52. Show or tell where you will check the fluid level in the engine cooling system.
Find and show the expansion capacity of the coolant, D in the figure.
53. Tell how you will determine that the coolant level is sufficient.
There are MIN and MAX markings on the coolant tank. Coolant should not be more than MAX or less than MIN.
54. Show or tell how you would check that all the lights are working.
When you turn on the ignition or start the car on the dashboard, the corresponding indicator lights (marker, low beam, high beam, front fog light or rear fog light) will light up together with the lights, so you can check the operation of these lights.
A warning light on the dashboard will notify you of a broken or burned-out headlight bulb (if such a function is provided in the car's system).
You will check the remaining lights visually (number plate light, stop lights, reversing lights).
Another option is to turn on the lights in turn and check visually (by walking around the car) to see if the lights are on.
55. Show or tell how the tachograph data carrier is changed.
The tachograph data carrier (card) is changed by removing the old card and inserting a new one. This requires you to insert a new card into the reader and perform the necessary actions, such as entering a PIN code or selecting a mode. After that, it is checked whether the card works properly and whether the data is registered correctly.
56. Tell me how you will manage the lift site. If there is no lifting platform in the test vehicle, how will you check that all doors, including the cargo compartment, are securely closed?
Turn on the control panel in the cabin, then you will control the site with levers or buttons.
If there is no lifting area, you will check visually and physically all doors, including the cargo compartment, are closed. 
57. Show or tell how you would check if the power steering is working.
After starting the car engine, the steering wheel can be turned more easily than before starting the car. This means the power steering is working.
If the steering wheel turns hard and requires a lot of physical force with the engine running, it means that the car does not have power steering or it is faulty. The warning light "Steering wheel with exclamation mark" can also warn of this (but it is not present in all cars)
58. Show or tell how you would check that the turn signals are working.
The car's ignition must be on for the turn signals to work.
To activate the turn signal, press the turn signal lever up or down. A green arrow (indicator) on the dashboard shows which turn signal is working and at the same time the turn lights on that side of the car are flashing.
The fault will be signaled by the green indicator light flashing more often than usual (very quickly), in some cars a message about a burnt out bulb may be lit on the dashboard.
Turn signals can be checked by going around the car and checking whether the turn signals on both sides are working.
59. Show or tell where the window washer fluid refill is.
Locate and display the window washer fluid tank.
The window washer fluid reservoir (container) is located under the hood. The tank is usually not visible, but the tank cap is visible. Most often, the cap is blue in color (other colors may also be available, e.g. black, yellow).
The cap of the container is marked with a windshield and running water on it.
60. Show how you will check if the windshield washer system is working.
You pull the lever on the right side of the steering wheel towards you: this activates the window washing system on the windshield.
Other cars may have a rotating lever tip that releases the window washer fluid. Still other cars may have a button to be pressed on the back of the knob to activate the wash assist system.
The most important thing is to remember to hold this button or lever so that the window washer fluid flows and cleans the glass effectively.
61. Show which instrument readings you must check before starting the engine.
On the panel, watch the glow plug indicator - it must go out, pressure gauge, oil level indicator, fuel gauge.
62. Show which instrument readings you must check after starting the engine.
Observe the air pressure, oil pressure, temperature indicators, voltmeter in the panel. Pay attention to whether the malfunction indicator lights are on.
