When passing through railway crossings, sharp curves, narrow roads, narrow bridges, curves, bridges, tunnels, or sections covered with snow, ice, or mud, the speed must not exceed 30 kilometers per hour in all these areas; 2. When making U-turns, turns, descending steep slopes, encountering visibility below 50 meters, or when towing another motor vehicle, the maximum speed must also not exceed 30 kilometers per hour.

What Causes a Car Tire to Blow Out?

Causes of car tire blowouts: 1. Low tire pressure; 2. Overinflation; 3. Incorrect installation; 4. Lack of proper maintenance; 5. Tire wear and aging; 6. Sidewall bulges or defects; 7. Severe impact. Measures to prevent tire blowouts: 1. Replace tires in a timely manner; 2. Perform wheel alignment and tire balancing; 3. Rotate front and rear tires; 4. Maintain proper tire pressure; 5. Avoid speeding. How to handle a tire blowout: 1. Firmly grip the steering wheel and gently adjust the direction; 2. Avoid sudden steering or hard braking—wait for the car to slow down before gently steering; 3. Set up a warning triangle behind the vehicle to prevent secondary accidents.

Why was the subject four test appointment automatically canceled?

Subject four test appointment being automatically canceled may be due to duplicate appointments, and the system may automatically cancel to ensure accuracy. Here is a detailed introduction about subject four: 1. Introduction to subject four test: The subject four test is the safety and civilized driving common sense test, conducted after passing the road test. In fact, there is no official term called "subject four"; the formal name is "safety and civilized driving common sense test." However, most students and driving schools are accustomed to calling it subject four to distinguish it from the subject three road test. The passing standard for the subject four test is 90 points. 2. Explanation of subject four test retake: If you fail the subject four test, you only need to retake subject four. The driving school will schedule the retake for you, and there is no limit to the number of retakes. You can retake it until you pass, and no retake fee is required for subject four retakes.

Is it allowed to temporarily park while driving a motor vehicle in a tunnel?

When driving a motor vehicle in a tunnel, temporary parking is not allowed. Motor vehicles are prohibited from parking at intersections, railway crossings, sharp curves, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, and within 50 meters of these locations. Temporary parking of motor vehicles on the road should comply with the following regulations: 1. Parking is prohibited in sections with no-parking signs or markings, sections with isolation facilities between motor vehicle lanes and non-motor vehicle lanes or sidewalks, crosswalks, and construction areas; 2. Parking is prohibited at intersections, railway crossings, sharp turns, narrow roads less than 4 meters wide, bridges, steep slopes, tunnels, and within 50 meters of these locations; 3. Parking is prohibited in front of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (posts), and within 30 meters of these locations, except when using these facilities.

Why is the spare tire pressure 420?

The spare tire pressure is 420 because the tire pressure during storage should be higher than the standard upper limit, but it should be adjusted to match the standard tire pressure of the original tires when in use. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates localized wear of the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches the tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass, the tire is more prone to punctures, leading to internal cracks, blowouts, and potential tire bursts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire components, leading to excessive rolling and abnormal heat generation; Weakens the function of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, sharply raising tire temperature, softening the tire, and drastically reducing strength. High-speed driving may lead to tire bursts; Increases tire deformation, leading to sidewall cracks, flexing movements, excessive heat, rubber aging, cord fatigue, and breakage, while also enlarging the tire's contact area and accelerating shoulder wear.

What Impact Does a Driver's Safe Driving Record Have?

Querying a driver's safe driving record serves to encourage safe driving practices. Below is expanded information regarding traffic violation handling: 1. Timeframe: Vehicle owners must address violations at the local traffic police station where the violation occurred. Failure to do so within 15 days will incur a late fee of 3% per day, although the total late fee will not exceed double the original fine amount. Early resolution helps avoid unnecessary penalties. 2. Verification method: The quickest and most effective way to confirm whether you have committed a violation is to inquire at the vehicle management office or traffic police station. Essential documents to bring include your driver's license, vehicle registration certificate, and ID card—all three are mandatory. It's also advisable to carry some cash, so that if a violation is found, you can promptly complete the necessary procedures.
