Vehicle Basic Test

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 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.

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.

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.

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.

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.

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.

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.

If the engine oil level is above the maximum mark, you should drain the excess from the sump to prevent engine damage. Overfilled oil can cause excessive pressure, leading to leaks, seal damage, or even engine failure.

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.

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.

If you adjust your side mirrors and can only see the sides of your vehicle, it means your mirrors are adjusted incorrectly. They should be angled outward so you can only see a small portion of your car's side, allowing for a wider view of the road and traffic behind you. The goal is to see as much of the lane beside you as possible, not your own car.

Proper mirror adjustment helps reduce blind spots, making it easier to spot vehicles approaching from behind and beside you, which improves overall road safety.

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.

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.

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

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.

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.

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.

When you enter a vehicle for the first time, the first thing you should do is to adjust your seat and steering wheel to ensure you have a comfortable and safe driving position. This will allow you to reach all controls comfortably and maintain proper posture for driving. After that, you can adjust the windows, gears, and pedals as needed.
