First, road type signs

Before going out, some preparations will be made more or less. If you haven't remembered the road names, just remember a few letters. At present, the road networks between cities in China are mainly divided into expressway, national highways and provincial highways, and the first letters in the road signs are respectively reflected. Detailed explanation: Precautions for driving at high speed

1. expressway

expressway is a high-grade highway, which is completely closed, and the traffic speed is the highest highway level in China. In the signpost, expressway is the same as the national highway, starting with the letter "G", such as G65 Expressway.

the letters of provincial expressways begin with "s", such as S9 expressway, etc. Both national expressways and provincial expressways are in white font with green background, with red stripes above the national expressway and yellow stripes above the provincial expressway. It should be noted that the expressways starting with the letters "G" and "S" are all totally enclosed in expressway, but the sign starting with "S" means that this section belongs to a certain province and has no other meaning.

2. National Highway

National Highway is a highway traffic trunk line that connects important areas of the country and plays a supporting role in the highway network. National Highway starts with the letter "G" in the road sign representation, for example, National Highway G323 has a white font and a red background, which is very easy to recognize. National Highway is an open road.

3. provincial highways

provincial highways are also called provincial trunk highways. In the signboards, provincial highways begin with the letter "S", such as the S233 provincial highway, which is black in font and yellow in background color, which is also eye-catching. Like national highways, provincial highways are also non-closed roads.

2. Common signs on the road

1. Destination information

The distances of key cities and regions passing through expressway will be reminded and marked at regular intervals. We can know the destination distance through these tips, and we can plan the arrival time, rest, refueling and other arrangements in advance.

2. Lane and speed limit information

Above the carriageway of expressway, lane information tips, including speed limit tips, will be displayed at intervals, and lane names or restricted vehicles will be displayed above. What you need to pay attention to is that the speed limit information of each lane is different. If you drive 121/km in the lane with a speed limit of 111/km, you will also be caught violating the rules by monitoring.

3. Service area information

The street sign of the high-speed service area is indicated by the capital letter P, and it is matched with the pattern of tanker, knife and fork and wrench. Service areas usually have restaurants, small supermarkets, toilets, gas stations, repair shops, etc., which can provide services that travelers may need. Generally, there will be a service area within 21-31 kilometers, and the interval between service areas in more remote areas may be longer.

4. Toll station information and toll lane warning lights

When we enter or leave expressway, we will stop to pick up the card or charge. Usually, the sign on the right side will give a warning 2 kilometers in advance. When we see the sign with the words toll station, we should slow down the speed appropriately and prepare for lane change in advance according to the instructions of the vehicle lane.

When the traffic volume is not large, the toll collection windows of toll stations will not all open. To know whether the lanes are open, you should look at the information on the display screen at the top of the toll station. The green arrow is open, and the red fork means not open. Drivers and friends should observe before making a judgment, so as not to cause inconvenience to themselves.

III. Signs for special sections

1. Tunnel signs

When expressway drives to the mountain road area, some high-speed sections will drive through the tunnel. At the entrance of the tunnel, you will see information signs about the tunnel, with the name of the tunnel indicated above and the length of the tunnel below, reminding drivers to prepare accordingly.

2. signs for climbing lanes

signs for climbing lanes are often seen on uphill sections, which are specially prepared for large trucks. Due to the restriction of geographical conditions, uphill sections will appear, but the heavy load of the cart will affect the normal traffic of other vehicles when climbing again, so the climbing lane is specially built for the cart, and parking in the lane is not allowed at will.

3. Warning sign for the safe lane

Another sign is common in areas with many downhill slopes, which is a lane built to prevent brake failure. When you see this sign, there will be a 45-degree slope ahead, which is the safe lane.

Editor's comment: In fact, it is not that difficult to recognize the sign on the expressway. As long as you make a good plan before going out, you can fully cope with the sign instructions. Novices should not be afraid and nervous after going to expressway. Relax and drive carefully, and there will be no problem. If the owner's friend misses the exit on expressway for some reason, don't panic, just drive to the next exit, after all, safe travel is the most important thing.

★ Correct understanding of high-speed signs

Source: car home Author: Guo Xiao

In the past National Day holiday, there were many accidents on the expressway. After the holiday, many accident videos were posted on the network, among which the sudden stop of the expressway, sudden continuous merging or even high-speed U-turn caused a high proportion of dangers. While condemning this practice and emphasizing safety awareness, we have to wonder why they made such dangerous behaviors. Many of these are caused by missing the exit or ramp. On the one hand, we missed the exit because of insufficient concentration, on the other hand, we were not familiar with the high-speed signs, so today we will talk about the high-speed signs.

Many friends may complain that they checked well before leaving, and the route on the map is very clear. Why do they feel dizzy when they see all kinds of brands and places on the road?

indeed, the routes we plan on the internet or navigation are all made for our personal needs. On the expressway, in order to ensure that people passing through different starting and ending points of this section can understand the signs, it is inevitable that there will be some "poor care", but these do not matter. There are several points to remember that can effectively avoid us from fainting.

● Remember the road section number and know the road type

Usually, we will make some preparations before going on the road, which road to go in and which direction to turn on, so the road name and direction need to be remembered clearly. If you haven't remembered the name of the road, no one can help you, so it is the first task to at least understand the road information simply.

At present, the road networks between cities in China are mainly divided into provincial roads, national roads and expressway. How to reflect them in road signs needs to be understood.

provincial highway

provincial highway is also called provincial trunk highway. In the signpost, provincial highway starts with the letter S, such as S111 provincial highway, which is in black font with yellow background, which is very easy to recognize. Provincial highway is an open road.

National Highway

National Highway is a highway traffic trunk line that connects important areas of the country and plays a skeleton role in the highway network. National Highway starts with the letter G in the road sign representation, such as National Highway G114, which has a white font and a red background, and is also eye-catching. Like provincial highway, national highway is also an open road.

expressway

expressway is a high-grade highway, which is totally enclosed, and its traffic speed is much higher than that of national highways and provincial highways. In the signpost signs, expressway and the national highway start with the letter G, such as G2 Expressway, and the provincial expressway starts with S, such as S31 Expressway, etc., and all of them are in white font with green background, and there are red or yellow stripes on them (yellow is the provincial expressway).

It should be noted here that the expressways at the beginning of G and S are totally enclosed in expressway, but the sign at the beginning of S means that this section belongs to a certain province and city, which has no special significance.

● Know the common signs

Knowing the road information makes it easier to plan the next travel route. Taking Beijing to Qingdao as an example, according to the plan, we should first enter S15 Beijing-Tianjin Expressway, then G2 Beijing-Shanghai Expressway, then G18 Rongwu Expressway and finally G21 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.

It should be noted that when we remember the road number, 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 first passing city 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.

● Recognize the common road signs

Nowadays, there are many road signs indicating different meanings and directions. Let's list and explain some of them below.

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 31 kilometers or so.

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.

lane information

above the carriageway of the expressway, there will be lane information tips at regular intervals, including speed limit tips, and the lane names will be displayed here. It should be noted that the maximum speed limit in expressway is usually 121km/h, but the speed limit in some lanes, such as the outermost lane or the middle lane, may be slightly lower, so we should pay special attention to avoid being photographed by the speed camera while driving.

toll station information

when we enter or leave the expressway or pass through the provincial boundary, we will always take the action of collecting the card and charging. Usually, the right road sign will give a prompt two or three kilometers in advance. When we see the road sign with the words toll station, we should appropriately slow down the speed, widen the distance and make preparations in advance according to the vehicle lane instructions.

Information prompt of toll channel

In the case of low traffic volume, the toll window of toll station will not be fully opened, 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 indicates 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.

Distance reference

Sometimes we will hear a similar broadcast "There is an accident 21 kilometers from Badaling Expressway to Beijing ...", and this 21 kilometers is what we call distance reference, so when you hear similar news, you can look at the guardrail on the driver's left side in the middle of the road, and there will be a sign at the guardrail every kilometer. You can know your approximate distance on the expressway by the numbers on the sign.

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.

Let me ramble here:

Whenever it comes to keeping a safe distance between cars, lighting the lights in parallel, and so on, there are always friends who complain in their replies that this method will lead to endless traffic jams, which is very helpless. Don't say safe distance, even if you are not careful, you will be jammed by others.

In a previous article about lighting in parallel lines, a friend even bluntly said that lighting in parallel lines is even more theoretical. After I turn on the lights, the car will speed up, so it is better to add it directly while it is unprepared.

Indeed, this is a lot of problems reflected in our imperfect civilized driving life. As a driver, I objectively think that in some cases, there are indeed many good habits that are disheartened by the embarrassing reality. However, when we return to the specific road condition of expressway, the overall speed is fast. Although turning on the lights can't guarantee that you will succeed in merging, it can ensure that the next car will find you in time, which will achieve the goal, whether he is willing to give way to you or not. And according to my observation, in fact, there are far fewer quarrelling people in expressway than in urban road conditions, so we might as well try the effect of lighting and merging lines.

In addition, in the face of keeping a safe distance between cars, I always think that if we slow down for safety, we should make concessions, especially on the expressway. After all, the road is not an arena, and the car is just a tool to make our life convenient and comfortable. It is our only purpose to get there safely if we take a step quickly, and if we don't win money or land, I may not be able to change whether others have enough safety awareness, but for ourselves and our families, many people are actually willing not to compete. If we think about it this way, our mentality on the road may be calmer and the danger will naturally be far away from us.

Ten wrong ways of driving in expressway

The recognition of expressway street signs is only the most common knowledge and the basis of ensuring our safety, while uncivilized driving behavior on high roads is the core problem that often causes problems in expressway. So here are ten common illegal acts in expressway, I hope you will pay attention to it, or if that sentence is changed, it will be encouraged. (If there is anything missing, please leave a message and we will make it up in time.)

1. Speeding

Speeding is the most common traffic violation in expressway, which is also the most likely to cause a vicious accident. The danger of speeding is self-evident, as the saying goes, nine times out of ten accidents is fast, and the danger of illegal speeding is mainly manifested in the following three aspects: < P > First, speeding affects the driver's vision. The driver's vision and dynamic vision (the driver's vision in driving) will change with the change of vehicle speed. When the speed is 41 kilometers per hour, the average driver can see the objects within 211 meters ahead; At a speed of 111 kilometers per hour, you can only see objects within 161 meters. Speeding will narrow the driver's vision and weaken his vision, and it is difficult to effectively deal with the sudden danger ahead.

second, speeding prolongs the braking distance. The braking distance of the vehicle is mainly restricted by the speed. Due to inertia, the faster the vehicle speed, the greater the braking distance, thus increasing the possibility of accidents.

third, speeding affects the stability of vehicle operation. Especially in the corner, due to the centrifugal force, it is easy for the vehicle to slip or tilt. Under the same conditions, if the vehicle speed is increased by 1 times, its centrifugal force will increase by 3 times. Excessive centrifugal force will easily make the vehicle out of control and roll over.

2. Overtaking in the emergency lane

The accident mentioned in this article was caused by overtaking in the emergency lane. Emergency lanes, as the name implies, are used for "emergency driving or emergency parking". If you overtake from here, it is easy to rear-end with vehicles parked in the emergency lane because of breakdowns, flat tires, etc., and because the overtaking speed will be faster, it is very prone to fatal accidents.

in addition, even if there are no anchored vehicles parked in the emergency parking lane. But because
