If a tire is punctured by a nail but isn't losing air, it does not need to be replaced. You can drive the car at a low speed to a repair shop to have the tire patched. Below are some precautions regarding tire maintenance: 1. Pay attention to tire pressure: Both overinflation and underinflation can shorten the lifespan of a tire. Underinflation increases tire deformation, leading to cracks on the sidewalls and excessive flexing, which generates heat, accelerates rubber aging, and causes fatigue or breakage of the cord layers. Underinflation also increases the tire's contact area with the ground, speeding up wear on the tire shoulders. Overinflation causes excessive stretching of the tire cords, reducing the tire's elasticity and increasing the load on the tire while driving. This can lead to internal cracks or blowouts upon impact, and overinflation also accelerates tread wear and reduces resistance to punctures. 2. Regularly check front wheel alignment: Front wheel alignment significantly affects tire lifespan, with toe-in and camber being the primary factors. Excessive camber mainly accelerates wear on the tire shoulders, while incorrect toe-in (either too little or too much) primarily accelerates wear on the inner or outer edges of the tire.

What Items Are Included in Vehicle Safety Inspection?

Vehicle safety inspection includes three major parts: whole vehicle inspection, engine inspection, and chassis & body inspection. Below is the relevant introduction about vehicle safety inspection: 1. Introduction: In recent years, the number of motor vehicles in China has increased dramatically, and the issue of motor vehicle safety operation has become increasingly prominent. Strengthening the management of motor vehicles and paying attention to the safety technical inspection of motor vehicles have become an important topic urgently needing research and solution for the whole society, especially for the public security traffic management departments, and also provide a good opportunity for the development of motor vehicle safety technical inspection in China. 2. Classification: The inspection work integrates the above classifications and operates according to the performance of the vehicle. The main performances of the vehicle are divided into power performance, economy performance, safety performance, reliability performance, environmental protection performance, handling stability performance, passability performance, and ride comfort performance, etc. Therefore, the inspection of the vehicle starts from the inspection of these performances.

Will I Get Penalty Points for Making a U-Turn at a Left-Turn Red Light?

When driving in a left-turn lane without a dedicated U-turn signal, and there are no dashed lines at the intersection or gaps in the guardrail, you must follow the traffic signal ahead—no U-turns are allowed at a red light. U-turns are prohibited during designated no-U-turn times at locations with "No U-Turn" signs, and violations will result in penalty points. Whether a U-turn at a left-turn red light incurs penalty points depends on the following scenarios: 1. If there is a dedicated U-turn lane, you can make a U-turn directly without being restricted by the traffic signal. 2. If you are in a left-turn lane without a "No Left Turn" sign and there are dashed lines on your side of the lane divider, you can make a U-turn at the dashed line without being restricted by the traffic signal, provided it does not interfere with straight-moving traffic. 3. If there is an arrow U-turn signal, follow its indication. 4. If the left-turn lane has no "No U-Turn" sign but has a solid yellow line, do not cross the line for a U-turn; wait for the green light and cross the pedestrian crossing to make the turn. 5. If the intersection clearly has a "No U-Turn" sign, U-turns are prohibited even when the light is green.
