Tunnel driving requires the use of low beams because the light inside the tunnel is relatively dim. Reasons for turning on lights when entering a tunnel: Turning on low beams can alert vehicles in front and behind to your position, ensuring driving safety. In case of an accident or the need for sudden braking inside the tunnel, you should promptly turn on the hazard lights to warn following vehicles to slow down and avoid. Precautions for driving in a tunnel: Before entering the tunnel, slow down appropriately. The speed limit is usually 40 or 60 km/h. Upon seeing the tunnel sign, be sure to slow down in advance and then turn on the low beams. While driving in the tunnel, changing lanes or speeding is strictly prohibited. When exiting the tunnel, first reduce speed and then accelerate to leave.

Where is the steering wheel located in American cars?

American cars have the driver's position on the left side of the vehicle, the same as in mainland China, meaning they are left-hand drive cars and drive on the right side of the road. The vast majority of countries worldwide have the steering wheel on the left side, with only Commonwealth countries having it on the right. The placement of the steering wheel on the left or right primarily depends on a country's traffic regulations. If the traffic laws dictate driving on the right, the steering wheel is placed on the left to facilitate better observation of road conditions without obstruction from vehicles ahead, especially crucial during overtaking. If placed in the center, visibility could be blocked by the vehicle in front, affecting safety. In some countries like Japan, where traffic regulations require driving on the left, the steering wheel is placed on the right. The main advantage of left-hand traffic is its potential to reduce traffic accident fatalities, primarily for two reasons. First: Humans have an innate instinct to avoid harm. When moving quickly and detecting danger ahead, people instinctively lean or turn to the left, allowing them to use their right hand (usually the dominant hand) to protect their body and shield the left side where the heart is located.

Which button should be pressed to defog the interior while driving?

To remove fog inside the car, press the front window defogger button. The formation of fog on the windows is caused by the temperature difference between the cold outside and warm inside. When the interior temperature is higher than the outside temperature, fog forms. Precautions when there is fog inside the car: Drive at low speed and stay safe: When driving in heavy fog, control your speed, drive slowly, and maintain a safe distance from the vehicle in front. On roads with low temperatures and high humidity, thin frost can easily form, so avoid sudden braking. In foggy conditions, drivers should use the remaining visibility to focus on the lane divider lines. Ensure the windshield is clean in foggy weather, as condensation on the surface can severely impair visibility. Methods to handle fog inside the car: Wipe the interior glass with a cloth soaked in high-concentration dishwashing liquid, which can prevent fogging for about 24 hours. Purchase anti-fog products from car accessory stores or online and apply them to the glass to prevent fogging for up to 24 hours. Alternatively, use the car's heating system by turning up the heat. Turn on the automatic air conditioning and set the mode to defog, which will switch the system to external circulation, allowing fresh air to enter the cabin and gradually dissipate the fog. For manual air conditioning, first adjust the air direction to defog mode, activate external circulation to let fresh air in, and increase the compressor and fan speed to speed up defogging.

What should you pay attention to when driving on the road?

When driving on the road, you need to pay attention to driving mileage, avoid going out at night unless necessary, slow down if you are not confident about passing through a green light, and be aware of roadside vehicles and other situations. If your driving mileage is less than 2,000 km, avoid driving on provincial or national highways with too many large vehicles unless necessary, especially those with only two lanes in both directions. Do not drive on highways if your driving mileage is below 5,000 km. Avoid going out at night unless necessary, and pay attention to the use of lights when driving at night. If possible, open the window slightly to gather surrounding information through sound. Slow down if you are not confident about passing through a green light. Avoid overtaking casually. In case of an emergency, the first reaction should be to pull the handbrake. Electric vehicles often squeeze toward the middle of the road when passing by. In such cases, you can either overtake the electric vehicle in advance or slow down and wait for it to return to the roadside before proceeding. The core principle is to try to avoid multiple vehicles driving side by side as much as possible in advance.

What Are the Hazards of Driving Without Releasing the Handbrake?

Driving without releasing the handbrake can lead to significant brake wear, increased risk of traffic accidents, and vehicle rollovers. Significant Brake Wear: Driving with the handbrake engaged directly accelerates wear on the brake discs, causes the brake pads to harden due to overheating, and stretches the handbrake cable. This results in reduced braking performance and, in severe cases, may cause smoke to emanate from the rear of the vehicle. Prolonged driving with the handbrake engaged can also lead to seized brake calipers, brake fluid leaks, and excessively high brake fluid temperatures. If you find yourself driving with the handbrake engaged and notice a strong burning smell or smoke from the rear, immediately reduce speed, apply the brakes, and release the handbrake. Do not continue driving; instead, pull over, allow the vehicle to cool down, and inspect for any other abnormalities. Traffic Accidents: Forgetting to engage the handbrake while stopped on a slope is extremely dangerous. If the driver focuses solely on accelerating and releasing the clutch while neglecting the foot brake, the vehicle may roll backward, leading to an accident. Therefore, if the vehicle starts rolling backward while stopped on a slope, remain calm, quickly apply the foot brake to halt the vehicle, and then gently engage the handbrake. Vehicle Rollover: In high-speed driving or sharp turns, pulling the handbrake abruptly to decelerate during an emergency is a common misconception. In reality, this is incorrect and highly hazardous. The handbrake primarily controls the speed of the rear wheels. However, at high speeds, its braking force is minimal. If the handbrake is applied while driving at high speed, it can easily lock the rear wheels, snap the handbrake cable, and cause the vehicle to skid or even roll over.

What are the reasons for water in the driver's seat?

Water in the driver's seat may come from outside the vehicle, as a blocked drainage hole at the bottom of the driver's side window can easily lead to water accumulation in the driver's compartment. Below is relevant information about vehicle drainage holes: Concept: Vehicle drainage holes are outlets designed to drain accumulated water from the vehicle during rainy weather. Generally, drainage holes are located in the following areas: the front windshield in the engine compartment, the four corners inside the sunroof, the lower parts of the front and rear doors, inside the fuel tank cap, at the bottom of the spare tire in the trunk, and the gaps between the front and rear headlights and the body fenders. Precautions: There is usually a drainage hole below the fuel tank cap. If it becomes blocked, water may accumulate in the fuel tank during car washes or rainy weather, potentially causing damage to the fuel tank. The spare tire in the trunk is typically located in a relatively low part of the vehicle body. When driving through water, if the water level rises above the headlights, water may seep in and reach the interior. The drainage holes in this area are used less frequently.
