What is the speed limit with 200 meters visibility on the highway?
3 Answers
The maximum speed is 60 kilometers per hour when visibility is within 200 meters, and a distance of more than 100 meters should be maintained from the vehicle ahead in the same lane. The driver should also turn on the fog lights, low beams, clearance lights, and front and rear position lights to alert other vehicles for safety. Safe driving distances and maximum speed limits under various visibility conditions: Less than 500 meters but more than 200 meters: Low beams, clearance lights, and rear fog lights must be turned on, the speed should not exceed 80km/h, and a driving distance of more than 150 meters should be maintained. Less than 200 meters but more than 100 meters: Low beams, clearance lights, and front and rear fog lights must be turned on, the speed should not exceed 60km/h, and a driving distance of more than 100 meters should be maintained. Less than 100 meters but more than 50 meters: Low beams, clearance lights, and front and rear fog lights must be turned on, the speed should not exceed 40km/h, and a driving distance of more than 50 meters should be maintained. Less than 50 meters: Vehicles are prohibited from entering the highway. Vehicles already on the highway must turn on the relevant lights as required, exit the fog area, and the speed should not exceed 20 kilometers per hour. Introduction to highways: Highways refer to high-speed roads, compared to medium-speed and low-speed roads. In an environment where low speed is mainstream, low speed is the normal or standard speed, and where medium speed is mainstream, medium speed is the normal or standard speed. Precautions before entering the highway: Check the weather and road conditions, perform a safety check on the vehicle, study the driving route in advance, carry a vehicle breakdown warning sign and a fire extinguisher, and plan the driving and rest schedule in advance. Article 51 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states that when a motor vehicle is driving and receives a signal from a vehicle behind to overtake, it must give way to the right and turn on the right turn signal if conditions permit, and must not deliberately refuse to yield or accelerate. When reversing, the driver must observe the situation behind the vehicle and confirm safety before reversing. Reversing is not allowed at railway crossings, intersections, one-way roads, curves, narrow roads, bridges, steep slopes, tunnels, or busy traffic sections.
I've been driving for over 20 years, and when visibility drops to around 200 meters in foggy conditions, you must never exceed 60 kilometers per hour - it's extremely dangerous. I remember once encountering heavy fog on the highway; I reduced my speed to 50 km/h, turned on the fog lights and hazard lights, which prevented an accident. Maintaining proper following distance is crucial - at least 150 meters - otherwise you risk rear-ending the vehicle ahead if they brake suddenly. Pay special attention to slippery road conditions too; when tire traction is reduced, you need to drive even slower. Driving in fog requires extra caution - if visibility becomes too poor, pull over and rest rather than rushing. Getting home safely is what matters most. Regular checks of your lights and wipers are also essential to ensure clear visibility. In summary, keeping your speed between 50-60 km/h in such weather is the only safe approach.
As someone who frequently drives on highways, when visibility drops to 200 meters in heavy fog, I keep my speed between 40 to 50 kilometers per hour. Think about it—the normal highway speed limit is 120 km/h, but driving at half that in such conditions could still lead to trouble. Last winter, with thick fog on the highway, I reduced my speed to 45 km/h and managed to avoid a potential accident. Besides controlling speed, it's crucial to turn on both front and rear fog lights to help others see you. Also, increase your following distance—at least 100 meters is a must. Avoid blasting the air conditioning too hard inside the car, as it can cause fogging and obstruct your view. If the weather is particularly bad, it's wise to exit the highway early and take a break at a service area. Speed is something you can't afford to be careless about—safety always comes first.
