Can Tires with Small Cracks Still Be Used?

Can you overtake and change lanes on tunnel dashed lines?

Tunnel dashed lines do not allow lane changes. Inside the tunnel, you should follow the vehicle in front in sequence and avoid changing lanes or overtaking. Because tunnels have fewer lanes and relatively poor visibility, you should slow down in advance before entering the tunnel, observe the internal conditions clearly, and maintain an appropriate distance from the vehicle in front at the prescribed speed. Below are some related tips for driving in tunnels: Maintain a safe distance: Keeping a safe following distance and leaving enough space for avoidance is essential for safety. Generally, the distance between vehicles in a tunnel should be more than 100 meters. If the tunnel is relatively long, follow the corresponding safety distance as indicated. Do not use high beams: Using high beams for extended periods at night can affect oncoming traffic and the vehicle ahead, as high beams can temporarily blind drivers. Inside the tunnel, the difference in light levels between the inside and outside already makes it difficult for drivers to adjust visually. Adding high beams can increase the risk of danger, so avoid using them. Slow down and turn on low beams before entering the tunnel: When driving during the day, entering the tunnel causes an instant dimming of light, which can make it hard for the eyes to adjust quickly. Therefore, about 100 meters before entering the tunnel, you should reduce speed, increase the distance from the vehicle ahead, and turn on your headlights to enter the tunnel safely at a relatively slower speed. Generally, the speed should not exceed 60 km/h, but you can adjust based on the speed limit signs before the tunnel.

Should You Drive Fast or Slow Through Water?

When driving through water, you should slow down. The water surface creates a gap between the car's tires and the ground, causing the tires to lose traction. Waterlogged roads also have a certain buoyancy, and driving quickly through them will inevitably result in loss of traction. Even a small amount of water on highways can cause this situation. The speed limits on highways are based on solid scientific principles, so driving speed should be reduced in rainy weather—use the lowest gear and the slowest speed. It's essential to assess the water depth carefully, including the depth, flow rate, and conditions of the road beneath the water, as well as the width of the entry and exit points, to determine whether it's safe to proceed. If the water level reaches two-thirds of the front bumper or the tires, driving through the water poses a certain risk. Avoid tailgating the car in front, and while driving, do not release the accelerator or shift gears, as this can easily cause water to enter the exhaust pipe and affect the engine's operation. If the engine stalls midway, do not attempt to restart it. Instead, exit the vehicle immediately to assess the extent of flooding. If the water level exceeds half of the tire height, the driver should remove the key and roll up the windows to prevent water from entering the car. Call for rescue assistance as soon as possible or seek help to move the car out of the water to avoid prolonged submersion, which can damage the chassis. Alternatively, you can ask someone to help push the car out to minimize losses.

Can Perfume Be Placed in the Car?

Perfume can be placed in the car, but it may cause an explosion, so it is recommended not to place perfume. Here is an introduction to perfume: Types: Car perfumes can be roughly divided into three types: liquid, solid, and spray. Solid perfumes are inexpensive and come in cute and diverse shapes, favored by young car owners. Effects: High-quality car perfumes have long-lasting fragrances and can kill bacteria, but if chosen improperly, under the heat dissipation conditions of the air conditioning, they can not only affect the mood of people in the car but also their health. Hazards: If low-quality perfumes are used, they will not only fail to improve the air pollution inside the car but may also worsen it. Low-quality perfumes contain excessive levels of alcohol and fragrance, with overly strong scents that can cause dizziness, nausea, and other adverse effects on the human body.

Is it normal for the engine to get very hot after driving for a while?

It is completely normal for the engine to get very hot after driving for a while. Possible reasons for engine overheating include the following situations: Severe coolant deficiency: Failure to promptly inspect and replenish the coolant can easily lead to engine overheating, which is often caused by leaks in the radiator pipes and a severe lack of coolant. Water pump failure: If the water pump malfunctions, the water that conducts heat in the engine cannot circulate and renew in time. As a result, after driving for a while, the water temperature will rise rapidly, and the water temperature warning light on the dashboard will also illuminate. Cooling fan failure: A damaged cooling fan or a short circuit in the wiring can cause the fan to malfunction or operate at a slow speed, preventing the engine's heat from dissipating. This leads to an increase in engine temperature, and upon opening the engine compartment, you can naturally feel a significant amount of heat.

What is the displacement threshold for motorcycles to pay purchase tax?

Motorcycles with a displacement above 150cc are subject to a purchase tax rate of 10%, while domestically sold motorcycles with a displacement below 150cc are exempt from the previously required 10% purchase tax. Additional information is as follows: Requirements for motorcycles on highways: 1. License: A motorcycle driving license is mandatory. 2. No passengers and helmet required: Motorcycles on highways cannot carry passengers and must be ridden with a helmet. 3. Road rules: Motorcycles on highways must use the rightmost lane, with a maximum speed below 80km/h and above 70km/h.

Can You Still Drive If Water Gets Inside the Car?

You should not drive if water gets inside the car. Here are the possible scenarios when water enters the vehicle: 1. Still drivable: If the air filter gets wet, the engine may draw in some water vapor along with air into the intake manifold. This water vapor mixes with gasoline and burns completely, causing minimal impact on the engine. 2. Minor water ingress into the engine: If a small amount of water enters the cylinders and mixes with the engine oil, the oil quality deteriorates. Oil contaminated with water increases wear on engine components, potentially leading to louder engine noise and increased vibrations in the future. 3. Most severe case: If the engine starts but stalls after a few seconds and cannot be restarted, this is the worst scenario. Since water cannot be compressed, its presence in the cylinders while the engine is running at high speed can cause catastrophic damage—bent valves and connecting rods, seized pistons, severe cylinder wall wear, and even a bent crankshaft.
