Is a tire pressure of 280 normal for a car?

If it's in a cold state, a tire pressure of 280 is slightly high. If it's in a hot state, a tire pressure of 280 is normal because the temperature rises due to tire rolling, and the pressure increases accordingly. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and the damage to the engine will lead to the end of the car's life. Then, the tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. Both excessive and insufficient air pressure will shorten the service life of the tire. Insufficient air pressure will increase the deformation of the tire body, and cracks are prone to appear on the sidewall. At the same time, it will produce flexing motion, leading to excessive heat, promoting rubber aging, fatigue of the cord layer, and cord breakage. It will also increase the tire's contact area and accelerate shoulder wear. Excessive air pressure will cause the tire cord to be overstretched and deformed, reducing the elasticity of the tire body and increasing the load on the car while driving. If impacted, it may cause internal cracks and explosions. At the same time, excessive air pressure will also accelerate crown wear and reduce puncture resistance.

Is It No Longer Necessary to Display the Insurance Sticker?

Whether the insurance sticker needs to be displayed depends on the situation. In cities where electronic insurance policies have been implemented, it is not required. However, in areas where this policy has not been implemented, the sticker still needs to be displayed. Motor vehicle insurance, also known as auto insurance (referred to as car insurance), is a type of commercial insurance that covers liability for personal injury or property damage caused by natural disasters or accidents involving motor vehicles. The vehicle inspection sticker, compulsory insurance sticker, and environmental inspection sticker were all mandatory in the past and had to be neatly displayed on the front windshield. After the new regulations were introduced, the environmental inspection sticker has been abolished, and only the vehicle inspection sticker and compulsory insurance sticker need to be displayed.

Can you change lanes on a solid white line?

You cannot change lanes on a solid white line. Crossing a solid white line to change lanes is generally penalized as an illegal lane change, resulting in a fine and a deduction of 3 points. If an accident occurs due to crossing the white line to change lanes, the driver bears primary responsibility. Situations where crossing a solid white line is allowed: when the vehicle ahead breaks down and turns on hazard lights, causing congestion behind, and if traffic remains stalled for an extended period, vehicles may cross the solid white line to change lanes, provided it is safe to do so. If this situation is captured by traffic cameras and results in a violation notice, the penalty can be appealed through administrative reconsideration. For penalties that cannot be dismissed, it is generally recommended that drivers install a dashcam or use their phone's recording function to gather evidence, as this can strengthen their case when appealing the penalty.
