1. Straight signs and one-way signs
The straight sign is the easiest to identify. It appears most frequently in the ground markings on the road and is a forward arrow. After the traffic sign is completed, it is a circle with an arrow in it, indicating that this road can only go straight and cannot turn around. Similarly, there is a one-way street sign, which is a vertical rectangle with an arrow inside. This sign shows that this road is a one-way street, which can only be driven in one direction, and it is not allowed to go backwards or turn around halfway. They are similar in that they all have a straight arrow, but the difference is that the whole logo is different in shape, round and rectangular, which is easy to be confused.
2. No access and no entry signs
They are all round signs, but the difference is that there is a white circle and a white strip inside. These two signs are not only confusing, but even unknown to many people. The intensity of the prohibition of passage is relatively large, which is indicated by a white circle. Generally, there is a road ahead or there is no road or there is danger, so you can't go any further. You can't go forward if you are forbidden to enter, but there is not necessarily no road or danger, such as traffic control. For example, the door of a unit is closed to cars, such as a one-way street. In a word, these two signs can't be distinguished clearly, and they can't continue to pass after seeing them, so they choose other roads.
3. No parking and no long-term parking signs
These two signs are also very similar, a circular sign, which has a distinguishing sign of no parking and only a diagonal line of no parking for a long time. As can be seen from the symbols, the difference sign is stricter than the slash. No parking for one second, very clear. It is forbidden to park for a long time, which means you can park for a short time, but not for too long. As for how long it can stop, there is no clear stipulation. Generally, it's just the time to get on and off passengers or do some shopping on the roadside.
4. Left traffic sign and right traffic sign
These two are not only very similar, but also not easy to remember. Places that are often used to build roads need to be deliberately remembered. There is a trick, there is a triangle on it, and the direction of the triangle arrow passes from which side. It doesn't matter if you can't remember it. As long as you see this sign, it means that there is a road ahead or the road conditions have changed. You should slow down in time and get close to see which side is passing before changing lanes. Of course, if you look at the sign, you can know in advance which side to cross, you can change lanes in advance, and you'd better remember.
5. Speed limit signs and signs for lifting the speed limit
Everyone knows the speed limit sign. A circular sign with a red outer edge has a number written on it, no matter what the number is, the speed limit is. The sign for lifting the speed limit is a circular sign, the outside is black, and a number is written inside, but this number is crossed out by diagonal lines, and the number inside indicates how much the speed limit has been lifted. It usually appears in places with poor road conditions. Suppose a bad road suddenly appears on a normal road, the maximum speed limit will be lowered, for example, to 40km/h, and then the speed limit of 40km/h will be lifted after crossing this road. When you see this low speed limit lifted, you can drive at a normal speed limit.
