Car jump-starting method with a dead battery is: 1. Prepare two jumper cables and a vehicle that can supply power; 2. Remove the battery box clips to open the battery protective cover, exposing the positive and negative terminals of the battery; 3. Take one jumper cable, connect one end to the positive terminal of the dead battery and the other end to the positive terminal of the live battery, ensuring the positive and negative terminals do not touch to avoid short-circuit hazards; 4. Take the other jumper cable, first connect it to the negative terminal of the live battery, then connect the other end to the engine block or body of the dead vehicle, avoiding negative-to-negative connection; 5. Once the cables are connected, start the live vehicle to provide a reliable voltage to the dead vehicle, completing the jump-start.

Last time my car ran out of battery, I asked a friend to help with a jump start by the roadside. We parked both cars close together without touching and opened the hoods. First, I took out the red and black jumper cables. The red cable was connected to the positive terminals marked red on both car batteries. One end of the black cable was connected to the negative terminal (black) of the donor car, and the other end was grounded to the metal frame or a bolt of the dead car—never directly to the negative terminal of the dead battery to avoid sparking or explosion. We started the donor car and let it run for a few minutes to charge. Then, I tried to start my car. Once it started successfully, I let the engine idle for at least ten minutes to recharge the battery before driving off. When disconnecting, I removed the grounded black cable first, then the other end of the black cable, and finally the red cables. I wore gloves and goggles for protection the whole time. After the jump start, I checked if the battery was old or if lights were left on causing a drain. I recommend keeping a portable jump starter as a backup—safety comes first when driving, and you can’t be too careful.

The car suddenly wouldn't start while parked in the garage, so I quickly improvised a jump start. First, make sure both engines are off and the cables are of reliable quality without aging. When connecting, I attached the red wire to the positive terminal and the black wire to a grounding point to avoid accidents. After setup, I waited about five minutes before attempting to start the engine. Once it started, I didn't rush to drive off but let the car run for a while to recharge. Throughout the process, I carefully avoided spark areas, especially educating children at home to stay away. After jump-starting, remember to check the charging system, like the alternator, to ensure it's functioning properly and prevent repeated battery drain. It's advisable to develop the habit of turning off lights when parking to reduce battery wear—a simple yet practical tip.

After decades of driving, I've encountered multiple dead battery situations, and jump-starting requires caution. Properly connect the red positive cable clamp to the positive terminal, and attach the black cable to an unpainted metal engine ground. Wait a few minutes after starting before operating the vehicle. The disconnection sequence is crucial to avoid short circuits. Common rookie mistakes include incorrect cable connections or rushing to drive off, which can damage electrical systems. After jump-starting, I always check battery health or potential power drains for timely maintenance and safe driving.

What to Do When Forgetting to Bring Your Driver's License?

When you forget to bring your driver's license, it should be considered under two circumstances: when no traffic accident has occurred and when a traffic accident has occurred. Here are the specific explanations: When no traffic accident has occurred: If a licensed driver forgets to bring their driver's license and is stopped by traffic police for inspection of the vehicle license and driver's license, they can provide the driver's license number (ID number) for the police to verify. Currently, many cities allow this situation, and no points will be deducted or fines imposed. When a traffic accident has occurred: An electronic driver's license is only valid when no traffic accident has occurred. If a traffic accident has occurred, the physical driver's license must be presented.
