Vehicle Basic Test

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.

On-board diagnostics (OBD) indicator, often called the Check Engine Light, signals an issue with the engine or fuel emissions system. It suggests that the vehicle needs servicing.

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.

Parking lights (also called sidelights) are used when visibility is reduced but not enough to require full headlights. They help other road users see your vehicle, especially when parked on roads where lighting conditions are poor.

Seat belts are fitted in vehicles for safety on both long and short trips. They help protect you in case of an accident, regardless of the length of your journey.

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.

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

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.

Skidding is mainly caused by the driver as their actions like braking too hard, accelerating too quickly, or steering abruptly, even in decent weather conditions, can lead to a skid.

While weather conditions like rain can significantly increase the risk of skidding by making the road slippery, the primary factor causing a skid is usually driver error, such as improper handling of the vehicle controls.

For safety, it's essential to regularly check critical components of your vehicle such as lights, brakes, steering, tyres, and direction indicators. These are crucial for safe driving, as they affect the vehicle's performance and ability to respond to road conditions.

This inscription is commonly found on passenger-side (right-side) exterior mirrors because they are convex mirrors, which slightly distort the image to provide a wider field of view. As a result, objects appear smaller and farther away than they actually are, so drivers must be cautious when judging distances.

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

The correct answer is: "Vehicles should pull to one side."

When braking, a vehicle should not pull to one side, as this indicates uneven braking force, possibly due to worn brake pads, incorrect brake adjustment, or a brake system fault. Properly functioning brakes should apply even pressure to all wheels for a stable and controlled stop.

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.

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 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.

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.

Fog lights are designed to be used in conditions where visibility is seriously reduced, such as during fog, heavy rain, or snow. They provide a low, wide beam of light to illuminate the road directly in front of the vehicle without causing glare, which can help the driver see better in such conditions. They should not be used when visibility is clear or when not required, as they may cause unnecessary distraction to other drivers.

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.

Carbon fouling on spark plugs usually means that the engine is running too rich (too much fuel relative to air), which can be caused by improper tuning. This can lead to poor combustion and deposits on the spark plug.
