Can the compulsory insurance purchased from a 4S store for a new car be refunded?

Can the compulsory insurance purchased from a 4S store for a new car be refunded? The answer is yes. Here are some considerations when purchasing insurance: Choosing an insurance company: If you are selecting car insurance on your own, the first step is to find a suitable insurance company. Be cautious when choosing small insurance companies, especially those that are not well-known. This is because filing claims with them can be difficult and troublesome, and their limited nationwide service networks may cause significant delays in processing claims, wasting the car owner's time. Selecting insurance items: When insuring a new car, choosing the right coverage is crucial. The first essential coverage is vehicle damage insurance, which offers great value for money and covers minor scratches and collisions. Next is third-party liability insurance, which serves as a good supplement to compulsory traffic insurance. It costs slightly more but provides much better protection. Additionally, if you don’t have a garage or a fixed parking space, theft insurance is advisable. Other optional coverages can be selected based on your specific needs.

Is It Safe to Leave a Blanket in the Car During Summer?

Yes, it is safe as blankets are not flammable items. Items that should not be left in the car during summer: During the hot summer months, temperatures can get extremely high. If flammable items are left in the car, it can lead to spontaneous combustion. These flammable items include alcohol, disposable lighters, matches, firecrackers, etc. If you must carry these items, it is safer to keep them in a bag rather than in the trunk, as the trunk is not air-conditioned and is a confined space, making it prone to explosions. Car care tips: Some car owners fail to turn off the air conditioning before shutting down the engine. This seemingly harmless habit can severely damage the battery. When the vehicle starts, the air conditioning system automatically activates and begins operating, causing a significant instantaneous power load on the vehicle. Over time, this can harm the car battery. Continuing to use electrical devices after turning off the engine—such as prolonged use of in-car electronics or forgetting to turn off the headlights—means the car's alternator is not working. The battery then depletes without being recharged, which can reduce its capacity and potentially prevent the car from starting. Additionally, excessive discharge can cause significant damage to the battery itself.

What Must Be Observed During the Break-in Period of a New Car?

During the break-in period of a new car, it is essential to avoid emergency braking, long-distance driving, and high-speed driving. Avoid Emergency Braking: Sudden braking is a poor driving habit, especially harmful to the new car's engine, braking system, and chassis. Drivers should anticipate road conditions in advance, slowing down and shifting to lower gears. If an emergency situation arises requiring sudden braking, the clutch pedal should be depressed first to minimize engine impact. Emergency braking not only shocks the braking system during the break-in period but also increases the load on the chassis and engine. It is advisable to avoid emergency braking within the first 300 kilometers of driving. Avoid Long-Distance Driving: Driving long distances during the break-in period increases the continuous operation time of the engine, leading to accelerated wear of mechanical parts. Avoid High-Speed Driving: New cars have speed limits during the break-in period. Generally, domestic cars should stay within 40-70 km/h, while imported cars should not exceed 100 km/h. When the throttle is fully open, the speed should not exceed 80% of the maximum speed. Drivers should monitor the engine tachometer and speedometer to ensure the engine operates at medium speed. Typically, the engine speed during the break-in period should be maintained between 2000-4000 rpm.

Is it a violation if the left turn is too small and the vehicle runs over the corner of the opposite solid line?

A left turn that is too small and results in running over the corner of the opposite solid line is not considered a violation, but it is a traffic offense. Running over the corner of the opposite solid line is a traffic offense: Due to the long wheelbase of the vehicle, the turning radius of the front wheels is different from that of the rear wheels. Therefore, when turning, the front wheels may pass through, but the rear wheels may run over the end of the solid line. In most cases, this is not a deliberate illegal act. Traffic authorities will temporarily not penalize vehicles for this behavior, which can also be referred to as a grace period. However, if it happens again during this period, penalties may be imposed. Other situations where running over a solid line does not result in penalties: When police cars, fire trucks, ambulances, or engineering rescue vehicles are performing emergency tasks, they often occupy the driving lane. To avoid such special vehicles, running over a solid line will not be penalized. Usually, there will be traffic police on-site directing traffic, and following their instructions is sufficient. If stopped by a traffic officer and instructed to drive to a certain area to park, running over a solid line during this time will not incur additional penalties.

Should rear passengers in a car fasten seat belts?

Rear passengers in a car should fasten seat belts, with detailed analysis as follows: 1. Sitting in the rear seat without wearing a seat belt seriously threatens the safety of front-row occupants and poses hazards to oneself. During a collision, unrestrained rear passengers may violently impact the front seatbacks, potentially causing injuries to the nasal bridge, arms, cervical spine, etc. 2. Article 51 of China's 'Road Traffic Safety Law' stipulates that drivers and passengers must use seat belts as required while the vehicle is in motion. Failure to wear seat belts during vehicle operation constitutes a traffic violation.

Can 92 octane gasoline be used if only 93 octane or higher unleaded gasoline is recommended?

Only 93 octane or higher unleaded gasoline can be used, not 92 octane. Definition of unleaded gasoline: It refers to gasoline with a lead content below 0.013g/L, which does not have tetraethyl lead added as an anti-knock additive during the refining process, abbreviated as ULP (Un-Leaded Petro). Unleaded gasoline contains only trace amounts of lead from crude oil, generally one-hundredth of a gram per liter of gasoline. Its octane rating is 95, slightly lower than the octane rating (97) of other existing leaded gasoline grades. Function of unleaded gasoline: Using unleaded gasoline can effectively control harmful substances in vehicle exhaust, reducing pollution such as hydrocarbons (HC, which causes smog), carbon monoxide (CO, toxic), and nitrogen oxides (NOx, which forms acid rain). The most effective and simplest method to reduce emissions is to install a catalytic converter in the exhaust system. However, when the lead content in gasoline exceeds 0.013 grams per liter, the catalyst will become ineffective, failing to control vehicle exhaust emissions. This critical amount is the standard for defining unleaded gasoline. Vehicles using unleaded gasoline must have hardened valve seats in the engine that do not require lead lubrication. If not, after using several tanks of unleaded gasoline, a tank of leaded gasoline should be used to lubricate the valve seats.
