What to Do If Your Car Is Hit While Parked on the Roadside and the Culprit Cannot Be Found?

If your car is parked outside and gets scratched by another vehicle, you can check the dashcam to identify the other party's license plate number and then report it to the police. If there is no dashcam, you can also look for nearby surveillance cameras and request to review the footage. Ask around at nearby stores, businesses, or residences to see if anyone witnessed the incident. If you discover that your car has been scratched and the other party denies responsibility or refuses to compensate after communication, there is no need to continue negotiating—simply report the incident to the police.

What is the appropriate tire pressure for long-term parking of a car?

If the car is not used for a long time, it is best to increase the tire pressure slightly to prevent tire deformation and ensure usability. The front and rear tire pressure should be increased to 2.8-3.0 bar. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; The maximum pressure should not exceed 3.5 bar. Normal tire pressure in winter: In winter, the tire pressure should be based on the standard tire pressure of the car, with an appropriate increase of about 0.2 bar. Normal tire pressure in summer: Generally, the lower limit of the standard tire pressure is sufficient. For example, the lower limit for standard tires is 2.4 bar. If the car is often parked outdoors, the tire pressure can be about 0.1 bar lower than the standard to prevent tire blowouts due to high temperatures.

How to Handle Hydroplaning of Motor Vehicles on Highways in Rainy Weather

Under normal circumstances, when a front-wheel-drive vehicle experiences hydroplaning, due to the heavier front body, the rear wheels hydroplane first. At this time, the vehicle's tracking performance is still acceptable. When driving on highways in rainy weather, avoid harsh braking. In fact, slamming the accelerator is also not advisable, as its effect is equivalent to harsh braking. Hold the steering wheel firmly with both hands and gradually release the accelerator pedal to slow down the vehicle. When driving in the rain, it is advisable to reduce speed appropriately and minimize lane changes and overtaking maneuvers.

How to Drive an Automatic Transmission Car Through Deep Water

You must first get out of the car to observe the depth of the waterlogged road. If the water depth reaches about half of the tire height, it is best not to force your way through. When passing through deep water puddles, for manual transmission vehicles, try to use first gear and avoid accelerating or shifting to higher gears to rush through. Using a lower gear ensures the vehicle maintains sufficient traction. When an automatic transmission car passes through deep water puddles, do not use automatic mode; switch to manual mode beforehand. While crossing the water, try to avoid stopping, accelerating, or changing gears. If the water level is higher than the air intake, the engine may suck in water. If the engine stalls due to water intake, do not attempt to restart it.

How to Pass Subject 2?

Subject 2 offers a total of 5 exam attempts, with 2 remaining. It's crucial to maintain the right mindset and avoid giving up, as many students pass on their fifth try. Since previous attempts failed, learn from these lessons and identify the reasons for failure. Focus on understanding error-prone areas and sections that lack proficiency. Get back up where you fell—pay extra attention to details. Discuss any doubts with your instructor or peers to ensure the same mistakes aren't repeated. The issue might stem from overlooked details, such as incorrect seating posture, poor clutch control, or misaligned reference points—practice thoroughly to address these.
