The minimum speed limit on the highway fast lane varies depending on different situations: For roads with 2 lanes in the same direction, the minimum speed on the left lane is 100 km/h; For roads with 3 or more lanes in the same direction, the minimum speed on the far left lane is 110 km/h, while the middle lane has a minimum speed of 90 km/h. Important precautions for highway driving include: 1. Both the driver and front-seat passenger must fasten their seat belts, and the driver should not use mobile phones while driving; 2. Avoid making sudden steering wheel movements at high speeds; 3. Do not change lanes arbitrarily - when needing to change lanes or overtake, turn signals must be activated in advance; 4. Overtaking is only permitted using adjacent lanes, and vehicles must return to the driving lane immediately after overtaking - driving straddling or pressing against lane dividers is prohibited; 5. Reversing, driving against traffic, making U-turns or turns across the central divider, test driving, driving instructional vehicles, as well as overtaking or parking on ramps are all prohibited.

I understand everyone's concern about the rules of the fast lane on highways, so let me talk about the minimum speed. The leftmost lane on the highway is designed for fast overtaking, so you shouldn't drive too slowly. Generally, the minimum speed depends on the local speed limit—if the maximum is 120 kilometers per hour, you should maintain at least 60 to 80 km/h. This rule is mandated by national regulations to prevent slow-moving vehicles from causing congestion or frequent accidents. I've seen cases where drivers were fined 200 yuan and deducted 2 points for driving too slowly—totally not worth it. I recommend paying attention to road signs, especially during holidays when traffic is heavy. Maintaining an appropriate speed is not only safer but also more fuel-efficient. Don’t forget that the speedometer displays kilometers per hour (km/h), so don’t confuse it with 'miles per hour.' Driving on the highway is about finding a dynamic balance. Safety comes first, but efficiency shouldn’t be overlooked either.

Do not use fingernails or sharp objects to pry the edges of the film to prevent dirt from entering; 4. Avoid attaching suction cup items to the tint film for 1 to 2 weeks; 5. If there are bubbles, displacement, or blurred vision on the film, seek professional help immediately to avoid affecting driving safety. The benefits of car window tinting are: 1. It can block heat in summer, saving air conditioning energy; 2. It can reduce energy loss in winter, maintaining interior temperature; 3. It blocks UV rays, preventing direct sunlight on interior decorations, thus extending their lifespan and quality; 4. It reduces glare, ensuring safer and more comfortable driving.

What Are the Reasons for Continued Vibration at High Speed After Wheel Balancing?

The reasons for continued vibration at high speed after wheel balancing are: 1. Uneven tire pressure among the tires; 2. Deformation or bending of the drive shaft, excessive wear of the drive shaft ball joint; 3. Differences in the vehicle's toe-in and kingpin inclination angles; 4. Poor performance of the shock absorbers; 5. Severe aging of the engine mounts, which fail to absorb the vibrations generated during engine operation. The solutions for continued vibration at high speed after wheel balancing are: 1. Adjust the tire pressure of each tire to ensure uniformity; 2. Remove the drive shaft and perform wheel balancing; 3. Replace the drive shaft ball joint bearing; 4. Perform a four-wheel alignment to adjust the values of each inclination angle; 5. Inspect each shock absorber and repair or replace any faulty ones; 6. Replace the engine mounts.

How to Remedy Not Turning Off the Engine While Refueling?

The remedy for not turning off the engine while refueling is to immediately turn off the engine or switch the ignition to the ACC position. The impacts of not turning off the engine while refueling include: 1. Gasoline is an electrolyte, and with the engine and other instruments in operation, it can easily lead to instrument leakage, causing short circuits or open circuits in the wiring; 2. The exhaust pipe continuously emits exhaust gases, sometimes carrying sparks, which can easily create safety hazards; 3. Operating instruments generate a large amount of heat, accelerating the volatilization of gasoline, increasing the concentration of the gasoline-air mixture, which is difficult to disperse and can easily ignite or explode. The correct steps for refueling a car are: 1. Slow down and drive into the gas station slowly, then drive out at low speed after refueling; 2. Turn off the engine before refueling; 3. Start the car only after closing the fuel nozzle.

When encountering a flood while driving, the following measures should be taken: 1. Carefully observe the road conditions to determine if the water depth allows continued driving; 2. If the vehicle stalls in the flood, avoid restarting the engine and immediately exit the vehicle to a safe location; 3. While driving in water, firmly grip the steering wheel, control the speed, maintain higher RPMs to prevent water from entering the exhaust pipe; 4. Protect communication devices to avoid being stranded without rescue; 5. Drive on higher sections of the road and avoid meeting other vehicles in flooded areas; 6. Enter flooded sections only after the vehicle ahead has passed; 7. Avoid areas with large ripples, as there may be hidden traps or obstacles underwater.
