What is the speed limit on highways during rainy days?

[OCarson]

During rainy days, the speed limit on highways varies depending on road conditions, weather, and other factors. Below is relevant information about speed limits on highways during rainy days: 1. When visibility on highways during rainy days is less than 200 meters: Drivers should turn on fog lights, low beams, position lights, and front and rear position lights. The speed should not exceed 60 kilometers per hour, and a distance of more than 100 meters should be maintained from the vehicle ahead in the same lane. 2. When visibility on highways during rainy days is less than 100 meters: Drivers should turn on fog lights, low beams, position lights, front and rear position lights, and hazard warning flashers. The speed should not exceed 40 kilometers per hour, and a distance of more than 50 meters should be maintained from the vehicle ahead in the same lane.

I've been driving on highways for nearly 20 years, and I genuinely advise slowing down in rainy conditions. I remember one heavy rain when I was doing 120km/h on the freeway, the car ahead suddenly braked hard, and I almost rear-ended it because the wet road doubled my stopping distance. Now whenever it rains, I always reduce speed to around 80-100km/h. Though highway speed limit signs usually indicate 120km/h maximum, heavy rain reduces visibility and makes roads slippery – excessive speed increases hydroplaning risks. Especially in thick fog or torrential downpours, some exit ramps even recommend dropping to 60-80km/h. Wet tires have significantly reduced traction, making high-speed curves particularly hazardous. My advice: maintain at least double the normal following distance, resist the urge to rush, and prioritize safety. Keep wipers active for clear visibility – driving too fast in rain often causes accidents that waste far more time. Two decades of driving taught me this golden rule: halve your speed in rain for true security.

I am very familiar with traffic rules. On highways, the normal speed limit is 120 km/h, but in rainy conditions, you must slow down. The official recommendation is generally between 80-100 km/h. In heavy rain, slippery roads and reduced visibility may require an even lower safe speed, sometimes with specific speed limits displayed on road signs, such as 80 km/h. Regulations vary by location; for example, mountainous areas or tunnel entrances may require reducing speed to 60 km/h. Personally, I check weather reports and drive slower in heavy rain to avoid speeding tickets. Rainy conditions on highways affect visibility and braking, so maintaining a lower speed not only complies with regulations but also reduces accident risks. Relevant data shows that many accidents in rainy weather are caused by speeding, and safe following distances should also be increased. Adhering to adjusted speed limits protects both yourself and other drivers.

With my background in car repair, I know that tires are prone to slipping on highways in rainy weather. Water forms a film on the road surface, reducing friction, and driving fast can lead to hydroplaning. The usual speed limit of 120 km/h should be reduced to below 80 km/h in the rain to improve grip. Rain increases braking distance, and high speeds make it difficult to control turns. I often recommend checking the tread wear of tires; vehicles with poor drainage should drive even slower. Rain refracts light, affecting visibility, making 70-90 km/h a safer speed. Vehicle systems respond with a delay, so avoid sudden acceleration to maintain stability. Technically speaking, an appropriate speed can extend the lifespan of components.

I commute on the highway every day and always feel nervous driving in the rain. Although the speed limit sign says 120, I usually slow down to around 100 km/h in heavy rain for peace of mind. The splashing rain blurs the windshield, reducing visibility, and higher speeds make it harder to react to sudden situations. I increase the following distance to guard against sudden braking by the car ahead. The high humidity on rainy days makes me more prone to fatigue, so slowing down a bit helps conserve energy. I use the air conditioning to defog the windows and maintain clear visibility, driving steadily to avoid splashing water and affecting others. Simply put, reducing speed a little prevents small issues from becoming big problems. When the rain is heavy on the highway, it's best to maintain a steady driving pace of 80-100 km/h to ensure a safe arrival home.

I prioritize driving safety and understand the extremely high risks of speeding in rainy conditions. Accident statistics show a surge in crash rates during rainy weather due to drivers failing to reduce speed. Driving at 120km/h on highways during heavy rain can lead to hydroplaning, rear-end collisions, and fatal outcomes. I recommend lowering the speed limit to a controllable range of 60-80km/h to improve survival rates. Rain multiplies braking distances exponentially, while high speed blurs vision and makes obstacle avoidance difficult. Not slowing down doubles the danger and wastes precious life time. A reminder to drive slowly and maintain a calm mindset—prevention is better than post-accident rescue.
