How many times must the distance between cars be increased when driving in bad weather or at night?

When driving in bad weather or at night, the driving distance must be increased by more than 2 times.

(a) when the visibility is less than 200 meters, turn on the fog lights, low beam lights, position lights and front and rear position lights, the speed shall not exceed 60 kilometers per hour, and keep a distance of more than 100 meters from the vehicle in front of the same lane.

(2) When the visibility is less than 100 meters, turn on fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, the speed shall not exceed 40 kilometers per hour, and keep a distance of more than 50 meters from the vehicle in front of the same lane.

(3) When the visibility is less than 50 meters, turn on fog lights, low beam lights, position lights, front and rear position lights and hazard warning flashlights, and the speed shall not exceed 20 kilometers per hour, and leave expressway from the nearest exit as soon as possible. ?

Drive slowly in low gear.

Experienced drivers know that no matter the width of the road and the condition of the road surface, try to use the second or third gear when it rains, and the speed is not more than 30 kilometers or 40 kilometers per hour. Always pay attention to the distance between the cars in front and behind, and be prepared to take various emergency measures in advance. If you need to stop, slow down as early as possible 100 meters or so, and brake lightly, so that the rear car has enough emergency preparation time to avoid collision or rear-end collision due to excessive braking.
