What Are the Causes of Highway Traffic Jams?
2 Answers
Highway traffic jams are caused by: 1. Foggy and snowy weather conditions often lead to consecutive accidents, which are difficult to handle, forcing vehicles behind to remain stuck in the congestion; 2. Sometimes, human operational errors result in accidents, involving issues such as injuries or vehicle insurance claims; 3. Heavy traffic at provincial border toll stations can easily cause congestion. Similarly, due to severe weather or road conditions, road administration and traffic police may implement measures such as closing main routes, diverting traffic, or staggered releases. During diversions, most trucks are unwilling to exit the highway because local roads often involve frequent vehicle inspections and fines, leading to extended traffic jams.
I drive on the highway every day for my commute, and experience tells me that the most common cause of traffic jams is the morning and evening rush hours. There are just too many cars during those times, especially near the exits in big cities, where vehicles queue up slowly to enter the station. Additionally, frequent minor accidents, like rear-end collisions, force the cars behind to slow down and check, bringing the entire flow of traffic to a halt. Bad weather, such as heavy rain or fog, also causes drivers to slow down due to poor visibility, leading to congestion as cars pile up. Road construction is another hassle—holidays often bring roadwork, reducing lanes and causing jams as everyone tries to squeeze through. Bottlenecks like toll booths with excessive traffic also create long queues during peak hours. When traveling, I prefer using navigation to avoid congestion in advance, and choosing non-peak hours makes a big difference.
