DTT Vehicle Safety Checks 4

Question 1

What is the purpose of the windscreen washer fluid?

Accepted Answer

To clean the windscreen of dirt, insects, and road grime while driving

Answer

Windscreen washer fluid cleans the windscreen of insects, road grime, and dirt while driving. Always use a proper washer fluid with antifreeze properties — do not use plain water in cold weather as it can freeze in the system.

Question 2

What should you do if your vehicle's steering suddenly feels loose or pulls to one side?

Accepted Answer

Stop safely as soon as possible and do not continue driving until the fault is identified

Answer

Sudden changes in steering feel — looseness or pulling — can indicate a tyre failure, steering fault, or suspension problem. These are potentially critical safety issues. Stop safely immediately.

Question 3

What does a grinding or squealing sound when you apply the brakes usually indicate?

Accepted Answer

Worn brake pads or discs — the brakes need inspection and likely replacement

Answer

Grinding or squealing under braking is a warning sign that brake pads have worn to the wear indicator or beyond, or that brake discs are damaged. Immediate inspection is required.

Question 4

How should you deal with a tyre blowout while driving at speed?

Accepted Answer

Grip the wheel firmly, ease off the accelerator gradually, and steer gently to maintain control before braking slowly

Answer

In a blowout, resist the instinct to brake hard — this can cause a spin. Grip the wheel firmly, ease off the accelerator gently, maintain course, then slow down gradually and pull over safely.

Question 5

What is the purpose of the handbrake (parking brake) and when should you apply it?

Accepted Answer

To secure the vehicle when parked or stationary — always apply when parking or waiting on a slope

Answer

The handbrake holds the vehicle stationary when parked or when stopped on a slope. It must always be applied when parking. On a hill, it prevents the vehicle from rolling if the footbrake is released.
