Is driving in the sun more dangerous in winter? | Car "rumor" crusher

Nowadays, cars play an indispensable role in our lives. With the rise and development of things, "rumors" also arise.

Have you ever heard some "rumors" about cars but don't know whether they are true or not?

The car "rumor" crusher will decipher the truth behind the "rumors" for you one by one. Please take a look at the content of this issue.

01-Is driving in the sun more dangerous in winter ?

Myth: We all know that the sun is glaring in the summer and that we need to use sun protection when driving. However, what we don’t know is that the sun is even glaring and more likely to cause danger in the winter.

The truth: The above statement is true! This happens because the temperature is lower in winter, and there is less water vapor and carbon dioxide in the air, which increases the scattering and radiation of sunlight. Especially after it snows, the snow on the ground will increase the reflection of sunlight and make it more dazzling.

There are several ways to prevent sun glare while driving:

1. Maintain a safe distance between vehicles. No matter what the situation, maintaining a safe distance between vehicles can minimize the occurrence of traffic accidents.

2. Do not place any objects on the center console, as the objects on the center console will reflect light under the sunlight and affect the driver's vision. In particular, do not place reflective objects such as plastic-sealed license plates on the instrument panel.

3. Wearing sunglasses and polarized sunglasses can effectively reduce sunlight reflection, scattering, etc.

4. When using the sun visor, the driver can adjust the angle of the sun visor according to the light and line of sight.

02- Four-wheel drive vehicles will not slip when driving on icy and snowy roads

Rumor: As long as the car has a four-wheel drive system, it will not slip when driving on icy or snowy roads .

The truth: The above statement is a rumor! Even a four-wheel drive vehicle will still slip when driving on icy and snowy roads. The stability of a car comes from the friction between the wheels and the ground, also known as grip. When there is snow or even ice on the road, the friction between the wheels and the ground drops significantly. Although the four-wheel drive system can distribute the power of the engine to all wheels, providing better traction and starting power, if the tires cannot generate enough grip, the advantages of the four-wheel drive system cannot be effectively utilized.

If you drive in an area with prolonged snowfall, you need to replace your snow tires before winter. Snow tires use special patterns and rubber materials to alleviate problems such as wheel hardening caused by low temperatures, better ensure the friction between the tires and the ground, and ensure driving safety.

When driving in snowy weather, you should pay more attention, reduce speed, and avoid slamming on the accelerator and brakes to prevent the vehicle from skidding. If necessary, you can also install anti-skid chains to ensure driving safety.

03- The "little black spots" on the car glass can prevent it from cracking

Rumor : People often see some small black spots on the car's glass. In fact, this is not a useless decoration. On the contrary, it can protect the car windows and prevent them from bursting.

The truth: The above statement is true! These "small black spots" on car glass should be called ceramic sintering points, which are traces of ceramic materials sintered on the glass. They can be tightly combined with the glass. Under normal circumstances, small black spots cannot be removed from qualified glass. When the car glass is exposed to the sun in summer, the temperature of the metal frame around the car glass will rise, causing it to expand. The middle part of the glass has better light transmittance and heat dissipation, which forms a contrast with the edge of the glass. This situation easily causes the glass to deform. The toughness of glass is poor, and deformation often leads to cracking, while these "small black spots" have the function of heat conduction and can also avoid some direct ultraviolet rays.

Therefore, using "little black dots" to transfer heat and reduce the pressure caused by the contrast can effectively prevent the explosion caused by deformation of automobile glass.

04- Car owners can customize their vehicles at will

Rumor : Some people believe that they are the owners of their cars and have the right to personalize the color of their cars.

The truth : The above statement is a rumor ! Car owners cannot paint their vehicles in a personalized way at will.

According to my country's Road Traffic Safety Law, any vehicle modification must comply with the provisions of laws and regulations. To change the appearance of a vehicle, the following prerequisites must be met:

First, the color of the vehicle is not allowed to be the same as the legal logo or color of police cars, ambulances, fire trucks, engineering rescue vehicles, etc., and it is not allowed to be painted in a way that affects driving safety. Secondly, if the body color is changed or the logo or body advertisement is sprayed, pasted, or the body of the motor vehicle is changed, an application for change registration should be submitted to the vehicle management office within 10 days after the change. If the body color is changed but the change registration is not handled within the prescribed time limit, a fine will be imposed... In addition, if the body color changes by more than 30%, the owner needs to go to the vehicle management office to file and change the driving procedures, otherwise the vehicle will not pass the annual inspection.

In short, the demand for "changing the look" of cars is reasonable, but it must also be done in accordance with the requirements of laws and regulations. It must not be changed at will and touch the bottom line of the law.
