Here are the methods to deal with a mouse in the engine: 1. If you find mouse droppings and urine, take the car to a detailing shop to clean the engine. It's also advisable to perform an engine wiring harness maintenance, which both preserves the harness and eliminates mice, killing two birds with one stone. 2. If you notice chewed wires or hoses, promptly visit an auto repair shop for repairs or replacements to avoid accidents. 3. If you discover mice in the engine compartment, immediately change the parking spot and clean the engine. Here are ways to prevent mice from entering the engine: 1. First, choose a good parking location; avoid parking in areas prone to mouse infestations. 2. Do not park in one spot for too long; regularly inspect the sealing parts of the undercarriage for any leaks or damage. 3. Keep your vehicle clean—avoid leaving food, biscuits, or edible garbage in the cabin, and dispose of such waste promptly. 4. Check whether the external air conditioning inlet and outlet filter screens are loose or damaged.

I've encountered the issue of mice getting into the engine compartment before. When I discovered it last time, there was already a whole nest of little ones settled in, which scared me into immediately turning off the engine for inspection. First and foremost, ensure safety—don't start the car again to avoid damaging the engine or causing a short circuit. Wear gloves and a mask to clean up the remains, using a brush and vacuum to remove feces and fur, paying special attention to whether any wires have been chewed. If there are signs of damage, such as exposed wiring, take it to a professional repair shop as soon as possible to prevent future problems. For prevention, I place rodent repellents like peppermint essential oil in the car and often park in open areas away from overgrown vegetation. Regularly opening the hood for inspections can prevent issues before they arise. From experience, spending half an hour on prevention can save thousands in repair costs. Mice love warm, sheltered spots, so extra caution is needed during autumn and winter. Developing this small habit can protect your beloved car.

Can I still drive if my car has 12 points deducted?

A driver's license with all 12 points deducted cannot be used for driving. First, let's correct a common misconception: vehicles cannot have points deducted; only driver's licenses can. In other words, points are deducted from the license holder, not the vehicle. If a driver's license has all 12 points deducted, it will be revoked, and the driver must retake the driving test. This test is commonly referred to as Subject 1. If a driver accumulates 12 points twice within a scoring cycle (12 months), in addition to taking Subject 1, they must also take Subject 3 (the road test). If a driver continues to drive with all 12 points deducted and is caught by traffic police, the vehicle will be impounded. The traffic management department of the public security authority may impose a fine ranging from 200 to 2,000 yuan and may also detain the driver for up to 15 days. For specific details, refer to Articles 23, 24, 25, 26, 27, and 28 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China.'
