What is the speed limit of Shenhai Expressway?

Expressway, referred to as expressway for short, refers to the expressway dedicated to high-speed driving of automobiles. Expressway has different regulations in different countries and regions, different times and different scientific research and academic fields.

Speed limit usually refers to the speed within a certain numerical range for a certain length and distance. The main purpose is to remind drivers to control the speed reasonably in advance to prevent the danger of speeding in the subsequent sections ahead. Speed limit is an indispensable link in highway transportation safety.

Speed limit is generally used to prevent drivers from causing safety hazards due to speeding. Freeways also have a minimum speed limit. Due to the high speed of normal vehicles on expressways and expressways, if some vehicles are too slow, they will become obstacles on the road and easily lead to rear-end accidents. Therefore, there will be a minimum speed limit on the expressway. Generally, the minimum speed limit in the left lane will be higher than that in the right lane. In case of traffic jam, the minimum speed limit will naturally be temporarily invalid. The minimum speed limit of expressway is generally 60 km/h.

Compared with ordinary highways, expressways have straight roads, smooth lines and gentle longitudinal slopes, and their overall structure has the following characteristics:

1, set up a car lane, which is forbidden for non-motor vehicles and pedestrians, and completely eliminate the interference of other road vehicles;

2. Set up a central isolation belt to completely isolate the vehicles in the round-trip direction to avoid scratching or collision of vehicles in the opposite direction;

3. Adopt overpass, and the whole section has no plane crossing, so as to eliminate the lateral obstacles of other highways and railways;

4, all control access, set up specific entrances and exits and interchanges, and vehicles enter and leave the expressway at designated points;

5, laying high-grade pavement, often using large radius curve design, both to avoid long straight lines and avoid sharp turns;

6. The combination of bridge and tunnel can save land resources, reduce environmental pollution and adapt to different terrain conditions.

Road Traffic Safety Law of the People's Republic of China

Forty-second motor vehicles driving on the road shall not exceed the maximum speed indicated by the speed limit sign. Keep a safe speed on the road without speed limit signs.

When driving at night or on dangerous sections, when encountering meteorological conditions such as dust, hail, rain, snow, fog and ice, the driving speed should be reduced. Article 67 Pedestrians, non-motor vehicles, tractors, wheeled special-purpose mechanical vehicles, articulated buses, all-trailer trucks and other motor vehicles with a designed maximum speed of less than 70 kilometers per hour are not allowed to enter the expressway. The maximum speed indicated by the speed limit sign on the expressway shall not exceed120km.
