What Causes Traffic Jams on Highways?

[LeLondon]

There are various reasons for traffic jams on highways. Adverse weather conditions and road conditions can lead to traffic control measures by road administration and traffic police departments. Improper human operations may result in accidents, while provincial border toll stations with massive traffic flow can easily cause congestion. Drivers should maintain a reasonable distance between vehicles on highways—neither too close nor too far from the vehicle ahead. Traffic jams are often prolonged processes with stop-and-go movement. Being too close during startup may cause scratches or rear-end collisions, while being too far may allow adjacent drivers to cut in, exacerbating congestion. When starting, drivers should also leave some space to react to the road conditions ahead. Therefore, during stop-and-go traffic, it's best to keep a distance of three to four car lengths from the vehicle in front. This ensures no cutting in from adjacent lanes while providing enough space for a smooth start.
