Can a car still run if the exhaust pipe is submerged in water? It should drive at a low and steady speed because constantly changing the throttle can cause fluctuations in exhaust pipe pressure. Additionally, as the water level rises, it may enter the intake pipe and air filter, causing the engine to stall immediately. This kind of stall has more severe consequences, as water entering the cylinders can hydrolock the engine, leading to mechanical damage. After driving through water, do not accelerate immediately; allow the water in the wheels to drain and test the brakes to ensure safety. For safety reasons, do not blindly drive through flooded roads. Understand the water depth and road conditions, and be familiar with your car's specifications, as different vehicles have varying heights for the air intake, air filter locations, and critical electrical component designs. Use low-beam headlights in rainy weather, and in heavy rain, turn on the front and rear fog lights. Avoid using high-beam headlights in rain or fog, as their angle can cause significant light scattering, reducing their effectiveness in such conditions.

Does the Court Support Compensation for Vehicle Depreciation Loss?

Generally, courts do not support compensation for vehicle depreciation loss, but they do support compensation for depreciation loss of new vehicles. The reasons why vehicle depreciation loss is not supported are as follows: 1. The "depreciation loss" of a vehicle is difficult to determine: For minor damages such as scratches or dents, the vehicle can be fully restored after repairs. For example, if components like headlights, bumpers, or doors are damaged and replaced, the vehicle may not depreciate but could even "increase in value." 2. Indirect loss: Vehicle depreciation loss is not an immediate direct loss but a potential indirect loss that may occur in the future. The "depreciation loss" of a vehicle is the difference between its value after repair and its value before the damage occurred. This difference only arises during a transaction; if no transaction occurs, there is no actual loss. 3. Lack of clear legal basis: According to China's Road Traffic Safety Law, in the event of a traffic accident causing vehicle damage, the compensation for the damaged vehicle itself is generally limited to restoring the vehicle to its normal usable condition—meaning only the repair costs are compensated, not the "depreciation loss."

Is driving a pickup truck at 120 km/h on the highway considered speeding?

On highways, the speed limit for small passenger vehicles is 120 km/h, while for trucks it is 100 km/h. In China, pickup trucks are classified as trucks, meaning they should adhere to the 100 km/h speed limit on highways. The details are as follows: 1. Speed Limit: Pickup trucks are categorized as multi-purpose trucks in China's vehicle classification. Although they are small in size, they fall under the truck category. According to China's Road Traffic Safety Implementation Regulations, the maximum speed for small passenger vehicles on highways must not exceed 120 km/h, while other motor vehicles must not exceed 100 km/h, and motorcycles must not exceed 80 km/h. 2. Penalties: According to traffic laws, if a small passenger vehicle exceeds the speed limit by less than 20%, a warning will be issued. For speeding between 20% and 50%, a fine of 200 RMB and 3 demerit points will be imposed. For speeding between 50% and 70%, a fine of 1,000 RMB and 6 demerit points or revocation of the driver's license may apply. For speeding over 70%, a fine of 2,000 RMB and revocation of the driver's license will be imposed.

Will Milk Spoil If Left in the Trunk for a Day in Summer?

Milk left in the trunk for a day in summer will spoil. Items Not Suitable for Storage in Cars: Sealed bottle products: High temperatures can cause the gas inside the bottle to expand without being able to escape, making explosions highly likely. Especially for perfume bottles made of crystal or glass, if exposed to direct sunlight, they can create a magnifying glass-like focusing effect, which can be very dangerous if focused on flammable items. Lighters: Ordinary lighters mainly contain liquid butane, which is flammable and explosive. High concentrations of butane can explode at just 20°C under normal conditions. If the ambient temperature exceeds 55°C, the lighter will expand. Fire departments have conducted experiments showing that a lighter left in a car under direct sunlight can explode in just 12 minutes, posing a significant hazard. Power Banks: Battery products like power banks, if left in a high-temperature car for an extended period, can swell and are highly prone to explosions. This is especially true for low-quality power banks that use substandard lithium batteries or modified batteries, which have even poorer stability.

What is the Difference Between Replacing a Damaged Driver's License and Replacing a Lost Driver's License?

The differences between replacing a damaged driver's license and replacing a lost driver's license are: 1. Processing Time: A driver's license that is about to expire can be renewed up to 90 days in advance to allow for proper time management and prevent the license from expiring; a lost driver's license must be replaced promptly. 2. Different Requirements: Before renewing a license, it is necessary to check for any traffic violations. If there are any violations, they must be resolved before renewal. However, replacing a lost license does not require this step. Below is an introduction to driver's licenses and vehicle licenses: 1. Driver's License (full name: Motor Vehicle Driver's License): Also known as a 'driving license,' it is a document issued by the government transportation department to individuals who qualify to drive, typically in the form of a card. 2. Vehicle License: It is the legal document permitting a motor vehicle to operate on roads within China, consisting of three parts: the document, the main page, and the supplementary page. The front of the main page contains the endorsed certificate core, the back features a photo of the motor vehicle, and the supplementary page includes the endorsed certificate core.

Does Forgetting to Replace the Oil Filter During an Oil Change Have Any Impact?

Forgetting to replace the oil filter during an oil change has no impact, and it is possible to change the oil without replacing the oil filter. However, it is generally recommended to replace both the oil and the oil filter simultaneously. Typically, the mileage interval for oil changes ranges from 5,000 to 10,000 kilometers, depending on the quality of the original oil and the vehicle's operating conditions. Oil Change Intervals: Generally, mineral oil can be replaced at 5,000 kilometers, while semi-synthetic oil can be extended to 7,000-8,000 kilometers. Full synthetic oil, being of the highest quality, can be replaced at around 10,000 kilometers. When it comes to selecting oil, it is not necessary to always choose full synthetic oil; instead, preference should be given to the vehicle's manual and professional advice. Oil Filter Replacement Interval: Since engine oil must pass through the oil filter (referred to as the oil filter) to reach the lubrication points, the role of the oil filter is to filter out impurities from the oil entering the engine system. This prevents the accumulation of impurities during the oil's circulation, which could lead to oil passage blockages or even severe engine damage. Currently, most passenger vehicles use non-detachable, disposable oil filters. Therefore, it is generally advised to replace the oil filter every 5,000 kilometers along with the oil change to ensure the oil provides optimal lubrication for the engine.
