DTT Vehicle Safety Checks

Question 1

How often should you check your vehicle's engine oil level?

Accepted Answer

Regularly — at least once a week or before a long journey

Answer

Engine oil should be checked at least weekly and before long journeys. Low oil can cause serious engine damage rapidly — waiting for the warning light may already mean damage has occurred.

Question 2

What should you check about your tyres before a long journey?

Accepted Answer

Pressure, tread depth, and condition (cracks or damage)

Answer

Before any long journey, check tyre pressure (including spare), tread depth (minimum 1.6mm), and condition — look for cracks, bulges, or foreign objects embedded in the tyre.

Question 3

What level should the brake fluid reservoir be at?

Accepted Answer

Between the minimum and maximum marks on the reservoir

Answer

Brake fluid should be between the MIN and MAX marks on the reservoir. Low brake fluid can indicate a leak or worn brake pads and should be investigated immediately.

Question 4

Why is it important to check the coolant level in your vehicle?

Accepted Answer

To prevent the engine from overheating and seizing

Answer

Coolant prevents the engine from overheating. If the level drops and the engine overheats, serious and expensive engine damage can result. Check when cold — never open a hot radiator cap.

Question 5

How should you check if your headlights are working correctly?

Accepted Answer

Switch them on and walk around the vehicle, or check reflections in a window or wall

Answer

To check headlights, switch them on and walk around the vehicle, or park close to a wall or garage door and observe the light projected. Ensure dipped and full beam work on both sides.
