What is the content of the Subject 4 driving test?

Subject 4 test mainly includes: safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods in situations such as tire blowouts, and knowledge of post-traffic accident handling. Additional information is as follows: 1. Introduction: Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driver's license assessment. The original test consisted of Subject 1 theory test, Subject 2 yard test, electronic Subject test, and Subject 3 road test. Subject 4 separates the requirements for safe and civilized driving, safe driving skills under complex conditions, and emergency handling knowledge from the original Subject 1, placing them after the actual road driving test of 'Subject 3' to further assess the candidate's traffic quality. 2. Retake instructions: If Subject 4 is not passed, there is no need to retake the previously passed subjects (Subject 1, Subject 2, Subject 3). Candidates can schedule a retake on their own, and no retake fee is required. There are no scheduling restrictions for the safe and civilized driving theory test, but the driving skill permit is valid for three years. If the applicant does not complete the test within the validity period, the passed subjects will be invalidated.

What is a retired vehicle?

Retired vehicles refer to those that have reached their service life in operations such as commercial transport, taxis, racing, or military use, and have been decommissioned from their respective professions. Vehicles designated for retirement are either those that have been in use for a long time and are nearing the mandatory scrapping age limit, or those that have encountered significant issues and can no longer function normally, leading to their retirement. For consumers interested in purchasing military-retired vehicles, they must complete the relevant documentation and apply for the used vehicle tax payment procedures at the vehicle registration location's tax collection department. If purchasing a retired taxi, the sale can only proceed once the vehicle's service life has expired, with the possibility of applying for a two-year extension on the scrapping deadline. For vehicles involved in civil litigation and adjudicated by the People's Court, the owner must present the original court ruling, an introduction letter from the employing unit or a copy of their personal ID. If the vehicle was previously registered, proof of the registration date from the vehicle management department is also required.

Where is the car's air conditioning filter located?

The location of the car's air conditioning filter varies depending on the vehicle model. Generally, it is installed under the front windshield of the car, covered by a drainage trough cover. The functions of the car air conditioning filter: 1. It ensures that the air conditioning filter fits tightly against the housing, preventing unfiltered air from entering the cabin; 2. It separates solid impurities such as dust, pollen, and grinding particles from the air; 3. It adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc., from the air, with strong and long-lasting moisture adsorption; 4. It prevents the car windows from fogging up, ensuring clear visibility for the driver and passengers, enhancing driving safety, providing fresh air to the cabin, and preventing the inhalation of harmful gases, thereby ensuring driving safety.

What are the causes of car valve leakage?

Reasons for car valve leakage: 1. Wear, burning, spots or depressions, and carbon deposits on the working inclined surface of the valve and valve seat ring; 2. Excessive clearance between the valve stem and valve guide, shaking of the valve stem or bending of the valve stem, and tilting of the valve head, resulting in incomplete valve closure; 3. Weakening or loss of elasticity of the valve spring or spring breakage can also prevent tight fitting between the valve and valve seat; 4. Small valve clearance, after the valve stem expands due to heat, the tappet and rocker arm push open the valve, preventing the valve from fully closing and causing leakage. The valve is an important component of the engine, and its function is to specifically deliver air into the engine and discharge the exhaust gas after combustion.
