Signs on the highway

All signs on the expressway include speed limit information sign, destination information sign, toll station traffic sign, distance reference sign, tunnel warning traffic sign and escape lane sign.

First, the highway number sign.

Expressway is a high-grade highway, fully enclosed, and the traffic speed is the highest highway grade in China. There are two kinds of expressways: national highways and provincial highways. In addition to the numbering of capital letters and numbers, there are also corresponding Chinese characters. Such as G30: Lianhuo Expressway and S28: Kaiyang Expressway.

Second, the road high and low speed limit signs.

The speed limit sign is set at the beginning of the speed limit section, and its main function is to tell the driver what the maximum speed limit and minimum speed limit of the section you are about to enter are, and it shall not exceed the maximum speed indicated by the speed limit sign and shall not be lower than the minimum speed limit. Above the maximum speed limit 10%, or below the minimum speed limit 10%, fines and points will be deducted.

Three, lane and speed limit information signs.

As the name implies, the speed limit of expressway is limited by the vehicle type and lane, that is, the vehicle type corresponding to the lane and the corresponding high and low speed limit, and the high and low speed limit of each lane is not the same. In addition, the rightmost emergency lane is prohibited from being occupied by any vehicle in a non-emergency state.

Four, highway bridge tunnel signs.

The information of highway bridge and tunnel signs generally includes name, length, height, bearing capacity, speed limit, no overtaking signs and how to use light tips.

It is worth noting that the speed limit of the bridge section of the expressway is basically the same as that of the main section, while the tunnel section will be reduced, and the basic top speed is about 80. This is also caused by the particularity of tunnel section.

Five, service area signs.

The sign of the expressway service area in the road sign is represented by the capital letter P, which is very easy to identify with different types of pictures representing the service area. Service areas generally provide catering, refueling, toilets, small supermarkets, repair shops and other services that passengers may need. Generally, there is a service area every 50 kilometers or so.
