What is the general validity period of a car fire extinguisher?

The validity period of the fire extinguisher cylinder is 8 years; the fire extinguishing agent has a shorter validity period, around one year, while carbon dioxide fire extinguishers have a validity period of 12 years; dry powder fire extinguishers have a validity period of 10 years; and water-based fire extinguishers have a validity period of 6 years. Maintenance intervals for car fire extinguishers: Water-based fire extinguishers should be sent for maintenance after 3 years from the date of manufacture, and then every year after the first maintenance; carbon dioxide and dry powder fire extinguishers should be sent for maintenance after 5 years from the date of manufacture, and then every 2 years after the first maintenance. How to use a car fire extinguisher: Carry the fire extinguisher to a location near the fire, stand upwind of the fire, pull out the safety pin, hold the nozzle tube firmly with one hand, press the handle with the other hand, and aim the nozzle at the base of the flames to sweep.

What are the vehicle inspection regulations?

New vehicle inspection regulations vary depending on the type of vehicle. Small and micro passenger vehicles: Building upon the exemption of non-operational small and micro passenger vehicles with 6 seats or fewer from inspection within 6 years, the exemption now includes non-operational small and micro passenger vehicles with 7 to 9 seats within 6 years. For vehicles older than 6 years but less than 10 years, the inspection frequency is adjusted from once a year to once every two years. Large vehicles: The minimum age requirement for applying for a large bus or tractor driving license has been reduced from 26 and 24 years old to 22 years old. The maximum age limit for applying for a medium or large passenger or truck driving license has been raised from 50 to 60 years old.

Should You Use Warm or Cold Air to Defog the Car Interior?

Use cold air to defog the car interior. In summer, you can adopt the air conditioning cooling method: Utilize the air conditioning's cooling and dehumidifying function to reduce air humidity and eliminate fogging. During summer, especially when multiple people enter the car without promptly turning on the air conditioning, the exhaled air has high humidity, quickly causing the windshield to fog up. At this point, turn on the air conditioning and direct cold air toward the windshield. By using the air conditioning's dehumidification feature, the fog on the windshield can be cleared shortly. However, if the humidity is excessively high and the air conditioning is ineffective, slightly opening a window can rapidly reduce the humidity inside the cabin. Of course, combining both methods will yield faster results. In winter, you can use the air conditioning warm air method: Employ the method of reducing temperature differences to eliminate fogging. In winter, direct warm air onto the windshield to quickly raise its temperature and minimize the temperature difference between the inner and outer surfaces of the glass. This helps prevent excessive fogging on the windshield promptly. Since the rear and side windows heat up more slowly, it takes longer to completely remove all fog from them.

Can I make a U-turn in the left-turn lane if there is a dedicated U-turn lane?

You cannot make a U-turn in the left-turn lane if there is a dedicated U-turn lane. If there are dedicated markings on the ground indicating U-turn and left-turn lanes, vehicles making U-turns and left turns should follow these markings and proceed separately, as they serve different purposes. Prohibited U-turn situations are as follows: U-turns are prohibited where there is a "No U-turn" or "No Left Turn" sign: If there is a sign prohibiting U-turns, then U-turns are not allowed at that intersection. Since a U-turn is essentially an extension of a left turn, intersections with "No Left Turn" signs also prohibit U-turns. U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If U-turns are permitted at an intersection, you must cross the crosswalk before making the U-turn and should not perform the U-turn on the crosswalk. U-turns are prohibited when there is no left-turn lane: Even if you are in the leftmost lane, U-turns are not allowed unless there is a sign permitting left turns. U-turns are prohibited in the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any signage, U-turns are only permitted in the innermost left-turn lane. U-turns are prohibited at solid yellow lines: U-turns are not allowed at solid yellow lines. Even if there is a sign permitting U-turns, you must wait for the green light and cross the stop line before making the U-turn. U-turns are prohibited on highways: Making a U-turn by crossing the central divider on a highway is illegal and will result in a fine and 12 demerit points. If you miss an exit on the highway, continue driving to the next exit instead of attempting an illegal U-turn.

What Should the Tire Pressure Be Adjusted to in the Desert?

Tire pressure in the desert should be adjusted to 1.6~2.0 bar. Lowering the pressure can improve the vehicle's off-road capability. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates uneven wear on the central tread pattern, shortening tire lifespan; increases body vibration, indirectly affecting the lifespan of other components; overextends tire cords, reducing elasticity and increasing the load on the vehicle during driving; decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, leading to internal cracks or blowouts, resulting in a tire burst. Hazards of insufficient tire pressure: Increases friction with the road surface, raising fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing excessive rolling and abnormal heat generation; reduces the functionality of cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and the ground, sharply raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to a tire burst; increases tire deformation, making the sidewalls prone to cracks and generating flexing motion, leading to excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area with the ground, accelerating shoulder wear.

What is the correct way to drive a manual-automatic transmission car on the highway?

For a manual-automatic transmission car, the method to drive at high speed is to first change the engine oil to allow the engine to adapt to the new oil. Start from the 1st gear, slowly press the accelerator, gradually increase the RPM for each gear, being careful not to hit the redline. Gradually raise the RPM for each gear and maintain medium-high speed operation for about 5 minutes. Introduction to manual-automatic transmission: Manual-automatic transmission combines the manual shifting and automatic shifting of a car. The manual mode allows drivers to freely adjust gears and RPM, providing a refreshing driving experience with a strong sense of sportiness and driving pleasure. The essence of manual-automatic transmission: The manual-automatic transmission is essentially still a type of automatic transmission, simulating the operation of a manual transmission through an electronic control system.
