Why is the speed limit on the Hubao Expressway set at 80?

[LeOlivia]

The speed limit on the Hubao Expressway is set at 80 to better prevent and reduce the occurrence of road traffic accidents. Expressway speed limits: Compared to driving on expressways, some people prefer alternating between expressways and provincial or county roads during long-distance trips, even if it takes longer. The monotonous scenery on expressways can easily lead to distraction, and prolonged driving increases the risk of accidents. However, many drivers still favor expressways for their convenience and speed, though frequent users often have numerous questions about them. Types of speed limits: Many people assume that expressways should have a speed limit of 120, but there are expressways with an 80 speed limit throughout. Generally, expressways designed for 80 km/h are often located in mountainous areas, high-altitude regions, or remote areas with challenging terrain. Even though the roads are well-constructed, immediate rescue may not be possible in case of emergencies. Therefore, "better safe than sorry"—lowering the speed limit also reduces the probability of accidents at the source.
