Vehicle Basic Test

The right foot is used to operate both the accelerator and the brake pedal, allowing for smooth transitions between speeding up and slowing down. The clutch pedal (in manual cars) is always operated with the left foot.

If the brake fluid level gets too low, it can affect the performance of the braking system, leading to brake failure or reduced braking efficiency. This significantly increases the risk of a crash, as you might not be able to stop the vehicle when needed.

While other fluids like antifreeze, radiator coolant, and battery water are important for engine function, they are less likely to directly cause a road crash if their levels get low, although engine overheating or electrical issues can still pose risks.

The warning light shown in the image represents the airbag warning light, which is part of the Secondary Restraint System (SRS). This system includes airbags and seatbelt pretensioners, which work together to protect occupants in the event of a collision. If this light appears on the dashboard, it indicates a potential issue with the airbag system that should be checked by a professional.

When this indicator light comes on, it usually signals that there is an issue with the engine oil level or pressure. You should check the engine oil level immediately to ensure that the engine is properly lubricated. Low engine oil can cause significant damage to the engine if left unchecked. It's important to top up the oil if it's low, or if the light stays on even after topping up, to have the engine checked by a mechanic.

Seat belts are designed to restrain passengers and keep them securely in their seats during sudden stops or collisions, preventing occupants being thrown out in an emergency and reducing the risk of serious injury or ejection from the vehicle.

Manufactured during the fifty-first week of 2007

To determine the manufacturing date of a tire, look at the last four digits of the Tyre Identification Number (TIN) found on the sidewall. These digits represent the week and year of manufacture.

For example, if the number is 5107:

• 51 = 51st week of the year
• 07 = Year 2007

This means the tire was manufactured during the fifty-first week of 2007

The total stopping distance is the sum of the thinking distance and the braking distance.

So, for this vehicle:

• Thinking distance = 18 metres
• Braking distance = 55 metres

Total stopping distance = 18 metres + 55 metres = 73 metres

The vehicle's total stopping distance will be 73 metres.

The primary function of a vehicle's suspension system is to absorb shocks and maintain consistent contact between the wheels and the road. This ensures better control, handling, and comfort while driving. It does not directly affect the electrical system or brake pads.

When the fuel pump symbol (fuel warning light) on your dashboard is lit, it usually means:

🚨 Low Fuel Level – Your fuel tank is running low, and you should refuel soon to avoid running out of fuel.

However, in some cases, it can also indicate:
🔧 Fuel System Issue – If the light stays on even after refueling, there might be a problem with the fuel sensor, fuel pump, or fuel filter.

⚠️ What to Do?

• Refuel as soon as possible to avoid getting stranded.
• If the light stays on even after refueling, have a mechanic check the fuel system.

The muffler is a device in the exhaust system designed to reduce excessive noise from the engine. It helps control sound by dampening and redirecting exhaust gases before they exit the vehicle.

The wiper on a vehicle helps the driver see clearly through the windscreen by clearing rain or debris, which improves visibility and safety while driving in adverse weather conditions.

The main cause of brake fade is overheating. This happens when the brakes are used excessively, causing the brake pads and discs to overheat, which reduces their effectiveness. Overheating can lead to a loss of friction, making it harder to stop the vehicle. Regular maintenance and avoiding excessive braking can help prevent this issue.

Rearview mirrors help drivers stay aware of traffic behind them, ensuring safe lane changes, turns, and reversing.

A properly serviced vehicle runs more efficiently, which can improve fuel economy and overall performance. Regular maintenance, such as oil changes, tire checks, and engine servicing, helps the vehicle operate at its best.

In an emergency braking situation, seat belts hold you in place and prevent you from being thrown forward. They are designed to reduce injury by keeping you securely seated, absorbing the force of sudden deceleration.

The hand brake is also known as the parking brake or emergency brake.

It is used to keep the vehicle stationary when parked or to assist in stopping the vehicle in an emergency.

When descending a steep hill, you should use first gear to control your speed. First gear provides the maximum engine braking, helping you maintain control of your vehicle and preventing it from gaining too much speed. Using a higher gear or putting the car in neutral could cause the vehicle to pick up speed more quickly, making it harder to control. Always use a low gear when descending steep hills.

When you change to a lower gear, the engine provides more resistance, which slows down the vehicle without relying too much on the brakes. This technique, known as engine braking, helps maintain control, especially on steep descents or in slippery conditions.

Leaving your radio on for a long period while the engine is off can drain the battery. The radio uses electrical power, and without the engine running to recharge the battery, the battery may become depleted. If the battery becomes too drained, you may have difficulty starting the vehicle. It's important to turn off all electrical systems, including the radio, when the engine is off to preserve battery life.

Driving with under-inflated tyres can affect fuel consumption. When tyres are under-inflated, they create more rolling resistance, which forces the engine to work harder, leading to higher fuel consumption.
