Sample questions

1. The following items may represent a danger for the driver during maintenance and servicing the vehicle:

   • the rotating components of the internal combustion engine
   • the chemical processes in the accumulator battery
   • the processes related to the air-fuel mixture formed in the carburettor

2. Is there any danger for the driver associated to electric cables when performing maintenance and servicing the vehicle?

   • yes, high-voltage cables are dangerous
   • yes, low-voltage cables are dangerous
   • no, electric cables in the vehicle are not dangerous for the driver

3. When opening the cap of the cooling system radiator at a coolant temperature above 70 degrees, there is a danger of:

   • evaporation of the coolant
   • cooling of the coolant
   • flushing and burning with hot coolant

4. When working on a vehicle lifted by a jack:

   • there are no associated dangers and there are no rules to be observed
   • measures must be taken against the vehicle moving on its own
   • measures must be taken against falling of the vehicle of the jack
   • measures must be taken against an engine start

5. The following items may represent a danger for the driver during maintenance and servicing the vehicle:

   • the processes related to the air-fuel mixture formed in the carburettor
   • the electric current generated by the accumulator battery
   • the hot components of the vehicle

6. With the engine running, the removal of a high-voltage cable of the ignition system and bringing it close to the vehicle “mass” near components of the fuel system is:

   • forbidden, as the resulting spark may cause a current shock or fire
   • necessary, in order to check the presence of high-voltage current
   • compulsory, in order to check the serviceability of the ignition system

7. When working on a vehicle lifted by a jack:

   • the vehicle clutch is disengaged
   • the parking brake is engaged
   • the transmission box is switched to direct gear

8. Mechanical jacks used for partial lifting of a vehicle:

   • must be fitted to special beds formed in the frame, bumpers or other suitable places
   • may be attached to the frame or the axles without any special beds designed for such a purpose
   • are attached to the most convenient place

9. In case of fire in the vehicle it is extinguished by:

   • by using a fire extinguisher
   • by using water

10. If fuel is spilled on the vehicle while charging, the vehicle must be cleaned and dried, as:

    • petrol vapours are highly flammable and fire- hazardous
    • petrol causes corrosion
