What are the speed limits for four lanes in the same direction?
2 Answers
If driving on a four-lane highway, the speed division for vehicles is as follows: when driving in the leftmost lane, the speed should be between 110 km/h and 120 km/h; when driving in the second or third lane, the speed should be between 90 km/h and 110 km/h; when driving in the rightmost lane, the speed can be below 90 km/h but not lower than 60 km/h. Unless in emergency situations or when the highway is congested, the speed can be below 60 km/h. Here are some additional details: 1. Speed limits for three-lane highways: In the same direction with three lanes, when driving in the leftmost lane, the speed should be between 110 km/h and 120 km/h, which is the overtaking lane; when driving in the middle lane, the speed should be between 90 km/h and 110 km/h, which is the driving lane; when driving in the right lane, the speed should be between 60 km/h and 100 km/h, which is the truck lane; and the rightmost emergency lane should not be entered unless in an emergency. 2. Speed limits for two-lane highways: In the same direction with two lanes, when driving in the left lane, the minimum speed should be 100 km/h, so the speed in this lane should be between 100 km/h and 120 km/h; while the speed in the right lane should be between 60 km/h and 100 km/h.
After driving for so many years, on a four-lane highway in the same direction, I usually observe that the leftmost lane is the fastest, used by drivers for overtaking, reaching the maximum speed limit of the road—for example, on highways, it might be 100-120 kilometers per hour. The second lane is the moderate-speed lane, with a balanced speed of around 90-110 km/h. The third lane is the slow lane, moving at a more conservative pace of 80-100 km/h. The rightmost lane is the slowest, often occupied by large trucks or vehicles entering/exiting the highway, with speeds possibly ranging from 70-90 km/h. This arrangement is designed to ensure smoother and safer traffic flow, minimizing speed differentials that could lead to accidents. I always remind myself to adjust according to road signs—avoid driving too slowly in the fast lane or overtaking in the slow lane, as this can easily lead to traffic jams or fines. Sometimes, inexperienced drivers on the road don’t pay attention, so I cautiously steer clear of them.
