What is the speed limit on the Shanghai-Chengdu Expressway?
2 Answers
The maximum speed limit on the Shanghai-Chengdu Expressway is 120 km/h. Expressways are multi-lane roads exclusively designed for bidirectional and multi-lane vehicle traffic with full access control. The average annual daily traffic volume for expressways should exceed 15,000 passenger car equivalents, with design speeds ranging from 80 to 120 kilometers per hour. Relevant information about speed limits is as follows: 1. Introduction to speed limits: Speed limits typically refer to regulations that set a specific range of driving speeds for certain road sections over a defined distance. 2. Purpose of speed limits: The primary objective is to preemptively alert drivers to reasonably control their speed in subsequent road sections ahead, prevent the dangers of speeding, and ensure driving safety. Speed limits are an indispensable and most crucial aspect of road transportation safety.
I've been driving for over a decade and I'm very familiar with the speed limits on the Shanghai-Chengdu Expressway. On most flat sections, the speed limit for passenger cars is 120 kilometers per hour, which is the standard speed on the G42 Expressway. However, when entering mountainous areas or sections with many curves, such as the Hubei segment or the edges of the Sichuan Basin, the speed limit drops to 100 or 80 kilometers. In tunnels, it's usually 80, so extra caution is needed. Once, I drove through the Yichang section where the speed limits change frequently, and it was only thanks to my navigation app's alerts that I avoided speeding. Safe driving is crucial—speeding fines range from 200 to 1500 RMB, not to mention the increased risk of accidents. On the expressway, speeds are high, and reaction distances are longer, so speed limit adjustments are in place to ensure everyone gets home safely. I recommend paying close attention to road signs rather than just memorizing numbers, as the Shanghai-Chengdu Expressway is quite long, and policies vary slightly between different provinces and regions.
