CERAD Theory Test. - VDI’s and Predriving Checks PREP QUESTIONS WITH ANSWERS What does VDI stand for? Vehicle Daily Inspection Why do we undertake VDI's? - To ensure vehicle is safe for intended use - To ensure vehicle is roadworthy - To the vehicle complies with all road traffic law - To ensure the vehicle satisfies all health and safety legislation - To set a good example to other road users When should you conduct a VDI? At the start of every shift, or if you switch to a different vehicle during the shift What should you do if you find a defect on the vehicle? Report in compliance with the service's policy so that such defects can be rectified A vehicle must not be used if it does not comply with road traffic law - true or false? True What items need to be checked during a VDI? 1. Examination of exterior 2. Wheels and tyres 3. Under bonnet checks 4. Lights and reflectors 5. All glass, wipers and washers 6. All audible warning equipment and exhaust 7. Ambulance-specific equipment/supplies What are you looking for when looking at the vehicle's exterior during a VDI? - Check it sits normally on the ground (not leaning one way) - Look below for any fluid leaks - Any damage to the bodywork - Ensure all body panels are in alignment and that all components (e.g., body panels, mirror brackets, tail lifts, locker doors) are attached securely - Check doors open/close - Check that fluorescent and reflective tapes or panels are clean Why do we need to look at the vehicle's exterior? - Adverse tilt could indicate a flat tyre, damage to the suspension, or incorrect loading - Fluids on the ground may indicate a fluid leak (note: aircon units can expel water - this is normal) - If you use the vehicle without identifying such damage, you may be held responsible - Any sharp edges or loose equipment can be construed as being in a 'dangerous condition' which could lead to prosecution under the Construction and Use regulations - Clean panels increase the vehicle's conspicuity What are you looking for when looking at the wheels and tyres during a VDI? - Ensure all wheel nuts are present and secure. If fitted, ensure all security indicators are correctly aligned - Look for scrapes/cracks which could weaken the wheel - Check tyre treads - Check tyre pressure - Check for tyre bulges, cuts, or other damage - Ensure no foreign objects wedged between twin wheels on the rear Sharp edges or loose equipment can be construed as in 'dangerous condition'. What could this lead to? Prosecution under the Construction and Use Regulation Why do we need to look at the wheels and tyres? - Wheel rims are prone to damage, especially those made of metal alloys - Especially important to check the security of the wheel nuts after a recent tyre change - The correct depth of tread is vitally important as it dispels water from the tyre road interface - Tyre faults can lead to catastrophic tyre failure - Uneven tyre ware can indicate issues with the suspension Why is the correct tread depth important? It dispels water from the tyre road interface What are you looking for when looking under the bonnet during a VDI? - Check engine oil, radiator coolant, power steering hydraulic fluid, brake fluid, Adblue, and windscreen washer levels are all up towards the maximum level - Some vehicles need the engine to be warm prior to checking oil dipstick levels - Check security of the fuel filler cap What is the 'clean hands check'? Some services have a policy where the fluids are checked by the vehicle's own diagnostic programme Why do we need to check under the bonnet? - Lack of engine oil or coolant could result in extreme engine wear and possibly an engine seizure - A low level within the brake or power steering reservoir could indicate a leak in the systems - Only use the correct oil/fluid Why is ensuring engine oil/coolant levels particularly important on an ambulance? Vehicles have to work in arduous (strenuous) conditions and are sometimes in use for long periods
