The reasons for a car horn not working include: 1. Insufficient battery charge; 2. Damaged horn relay or button; 3. Damaged horn. During normal vehicle use, if the sound is not crisp but rather muffled and weak, it indicates poor contact at the connection points. If the horn sometimes works and sometimes doesn't, it suggests poor contact inside the switch. If the horn doesn't work at all, check the fuse to see if it's blown, and use a multimeter to measure whether there is electricity at the point when the horn switch is pressed. On one hand, the car horn serves to alert pedestrians and vehicles on the road; on the other hand, it can prevent sudden appearances of vehicles at sharp turns. Therefore, if there is an issue with the car horn, it is advisable to promptly inspect and repair it at a repair shop or 4S store.

Will the engine be affected if the car is flooded and not started?

If the vehicle is in a static state, meaning it is parked and flooded, and the engine is not started, as long as the water level does not reach the air intake of the engine's intake system, the engine will not be damaged. The position of the air intake may vary slightly among different brands and models, but generally, it is located just below the engine hood, with some models having it slightly lower. If the water level does not reach this height and there are no signs of water in the air filter, the engine will not be harmed. Additional information regarding flooded vehicles is as follows: 1. High water level: The owner should not attempt to start the engine forcibly.

What happens if a vehicle is caught by traffic police driving without inspection?

If a vehicle is caught by traffic police driving without inspection, the driver will face a fine, 3 demerit points, and may even have the vehicle impounded. Driving an uninspected vehicle is considered illegal driving. If an uninspected vehicle is involved in a traffic accident, the driver will bear full or primary responsibility, and the insurance company will not provide compensation. If the vehicle has been uninspected for less than three months, the driver can directly apply for a re-inspection and will receive a verbal warning without a fine. If the vehicle has been uninspected for more than three months but less than two years, the driver will need to pay a fine and receive 3 demerit points. If the vehicle has not been inspected for more than two years, the vehicle's registration will be canceled, and the driver will need to pay a fine to reinstate it. If the vehicle fails to obtain an inspection compliance mark for three consecutive inspection cycles (interpreted as three consecutive missed inspections), it should be scrapped. If a vehicle that has been forcibly scrapped is driven on the road, the driver will face severe penalties, including fines and revocation of their driving license.
