What is the speed limit on the Jingxin Expressway?

[AlanAnn]

For large and medium-sized trucks, the maximum speed should not exceed 80km/h; for other vehicles, the maximum speed should not exceed 100km/h. There are three key points to note when driving on the expressway: 1. Entering the expressway: Drivers should accelerate to at least 60km/h as soon as possible. Vehicles entering from the ramp must increase their speed in the acceleration lane and should not hinder vehicles already on the main lane when merging. They should initially drive in the outer lane. 2. While driving: Vehicles should stay in their designated lanes. Small passenger vehicles should drive in the middle lane, while large buses and freight trucks should drive in the right lane. 3. Lane changes: Drivers must not change lanes arbitrarily. When changing lanes or overtaking, they must signal in advance with their turn indicators. At night, they should also switch between high and low beams to confirm safety before changing lanes. Overtaking is only permitted using adjacent lanes.
