When you get on the train in expressway, in the sections with heavy traffic, especially in service areas and interchange hubs, minor scraping and collision accidents occur from time to time, which seriously affects the traffic order of the road and leads to traffic congestion. Have you ever wondered why? Listen to your analysis. Many accidents are caused by some drivers' lack of concentration, unfamiliarity with the route, or unfamiliarity with the signs in expressway, which leads to a series of wrong behaviors, such as sudden stopping and sudden merging. This is the main driver of frequent accidents and a fatal mistake that is easy to make in expressway! Because there are many road signs on the road, the meaning and direction of the signs are completely different. The next time, not much, 1 minutes is enough. If you learn to read these road signs, you are really not afraid of losing your way. Let's give an example first. We went to Guangdong from Jingzhou, Hubei Province. According to the plan, we should first enter G55 Erguang Expressway, then transfer to G5513 Changzhang Expressway, and then enter S61 Yuelin Expressway. It sounds complicated, but we can't go wrong as long as we remember these numbers. And whenever we should change roads, there will be signs on the right side of the road every few kilometers, and the closer we get to the turning point, the more frequent they will be, so as long as we pay attention, we will definitely not go wrong. One thing to note here is that when we remember the road numbers, we should also remember the direction we are going to or the cities we pass through. Some directions of road signs will be indicated by the cities that pass first or the key cities in the general direction. They may not be our destination, but the names of these cities can be used as a direction guide, and we should also pay attention to them so as to avoid inconvenience caused by going in the wrong direction. With the above points in mind, we can avoid missing the exit or going the wrong way to the greatest extent. Ok, here are eight signposts. Please keep them. 11 service area This is a common indication on the expressway, and it is also a necessary place for us to rest and refuel during high-speed travel. The sign of the high-speed service area in the street sign is represented by the capital letter P, and it is very easy to identify with the pictures representing different types during the service period. Service areas generally provide catering, gas stations, toilets, small supermarkets, repair shops and other services that travelers may need. Usually, there will be a service area every 51 kilometers or so. 12 destination information The distance between our location and the key cities passing by the expressway will be reminded and marked at regular intervals. We can learn the destination distance information through these tips and make plans in advance for the arrival time, rest and refueling. Above the carriageway of 13 lane information expressway, there will be lane information tips, including speed limit tips, at regular intervals, and lane names will be displayed here. It should be noted here that the maximum speed limit in expressway is usually 1.21 km/h, but the speed limit in mountain bridges and tunnels will only be 1.11 km/h or 81 km/h.. 14 Toll Station Information When we enter or leave the expressway or pass through the provincial boundary, it will involve the action of picking up the card and charging. Usually, the road sign on the right side will prompt us two or three kilometers in advance. When we see the road sign with the words toll station, we should slow down the speed appropriately, widen the distance and make preparations in advance according to the vehicle lane instructions. The information of toll channel indicates that the toll window of toll station will not be fully opened when the traffic volume is not large, and the information of whether to open it is all reflected in the display screen at the top of toll station. The green check mark indicates the open state, and the red fork represents the unopened state. Everyone should make a judgment after observing in advance, so as not to drive into the unopened channel and cause inconvenience to themselves. 16 Distance Reference Sometimes when we listen to the radio, we will hear a similar broadcast "There is an accident at 1451km of Beijing-Hong Kong-Macao Expressway ...", which is what we call distance reference, so when you hear similar news, you can look at the guardrail in the middle of the road on the driver's left, and there will be a sign at the guardrail every kilometer. You can know your distance on the expressway by the numbers on the sign. 17 Distance Reference The most important thing when driving in expressway is to keep the distance from the vehicle in front. Of course, the cars are not popular enough to have the distance warning function. Therefore, the distance between you and the vehicle in front can be well grasped with the help of the distance warning board displayed on the roadside, so as to avoid vehicle accidents caused by too close distance. 18 bay parking area
