The hazards of insufficient power supply from a car battery include difficulty in starting, inability to start the vehicle, and weakened functionality of electrical equipment. Hazards of insufficient battery power supply: Causes unstable engine idling; reduces actual fuel injection quantity; weakens ignition energy, leading to failure to start; prevents the release of anti-theft alerts; locks the audio system; causes related systems to malfunction, and in severe cases, dims headlights or reduces horn volume. Car battery maintenance: Remember to turn off lights and audio before shutting down the engine: Drivers should ensure that lights and audio are turned off before parking and shutting down the engine. Leaving them on for extended periods increases the battery's burden and shortens its lifespan. Avoid long-term parking of the car: Cars should not be parked for long periods because prolonged inactivity leads to a gradual decrease in battery charge, which may result in difficulty starting the car when needed. Regularly clean the car battery: With prolonged use, the battery may accumulate dust, white powder, and other contaminants. To avoid affecting the battery's lifespan, use a damp cloth for regular cleaning and wiping to keep the battery's exterior as clean as possible. Conduct regular inspections of the car battery.

Can Subject 2 and Subject 3 be Scheduled Together?

Yes, they can be scheduled together for consecutive tests. According to Article 36 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": The vehicle management office shall arrange the tests according to the scheduled test site and time. After passing Subject 1, the applicant can schedule Subject 2 or Subject 3 road driving skills test. In areas with the necessary conditions, the applicant can simultaneously schedule Subject 2 and Subject 3 road driving skills tests and take them consecutively upon successful scheduling. Subject 2 Test Notes: The first thing after getting in the car is to adjust the seat and rearview mirrors to a suitable position and state, and always fasten the seat belt. (This seems like a no-brainer, but such basic mistakes are most likely to occur when nervous or flustered). For parallel parking, remember to find the right angle, turn the steering wheel quickly, and react promptly in coordination with the car's speed. For hill starts, remember to pull the handbrake, turn on the left turn signal when starting, release the handbrake, stabilize the clutch, and gently press the accelerator while releasing the clutch to avoid stalling or rolling back. For right-angle turns, react quickly to turn once the reference point is found, always coordinating with the car's speed to prevent deviation. For curve driving (S-turns), the safest method is to slow down. Those with good driving sense during practice can pass through swiftly in one go. For reverse parking, control the speed carefully, find your reference points, and make minor adjustments if you notice any deviation in the rearview mirrors. Subject 3 Test Notes: Pre-driving preparation: Walk around the car to check tire pressure and the vehicle's exterior. Before opening the door, check for passing vehicles or pedestrians. In-car preparation: Maintain a calm mindset, adjust the seat, check if the rearview mirrors need adjustment, inspect the handbrake, gear, and seat belt. Starting: Check if the dashboard is normal, look at the interior and exterior rearview mirrors, and turn your head to observe traffic behind you—make the movement noticeable for the examiner. Straight-line driving: Keep the car moving straight and turn off the turn signal. Control speed appropriately, maintain a safe distance, and monitor the rearview mirrors for sudden situations. Gear operation: Shift gears smoothly without looking down at the gear lever. Road and traffic handling: Overtaking: Choose the right moment to overtake promptly. Use turn signals when changing lanes. Oncoming traffic: Slow down in advance and proceed with caution. Lane changing: Observe carefully before changing lanes, confirm safety, then turn on the signal. Check the mirrors again to confirm safety before smoothly steering into the desired lane and turning off the signal. Pedestrian crossings: Slow down in advance and yield courteously to pedestrians and vehicles. Intersections: Observe carefully and slow down or stop if necessary. Follow the correct lane based on the driving direction. Pulling over: Slow down, assess road conditions, and choose a parking spot. Park smoothly with the body and wheels aligned. Exiting: Only exit after the computer announces the test is over. Always check the left rearview mirror for safety before opening the door.
