The common cause found is the driver's subjective error. Among them, a typical error is not understanding the high-way signal language correctly. If a driver really takes it seriously, he will see in the theory lesson before taking the driver's license exam that he must absolutely obey all signs. When traveling on the highway, the outermost lane is for higher speed vehicles. Only pass on the left and do not pass when there is a prohibition sign. Must comply with the speed limit, including not exceeding the maximum speed and not going below the minimum speed indicated on the sign, etc.

According to regulations, drivers who drive at a lower speed than other vehicles traveling in the same direction without moving to the right side of the road, except in cases where other vehicles traveling in the same direction exceed the prescribed speed limit, will be fined from 400-600 thousand VND. However, it is not difficult to see many car drivers still driving very leisurely below the prescribed speed, or many trucks and passenger cars on the far left lane, even though the car behind them is impatiently honking their horn or flashing their lights.

They may think that they are not wrong in not driving below the minimum speed, but in fact they are completely wrong in taking the left lane only for vehicles running at the highest speed, thus hindering other vehicles. That situation causes other drivers who want to go fast to pass on the right, then wriggle, making mistakes and causing risks and dangers.

Having had the opportunity to drive on the Tuyen Quang-Phu Tho highway in the past few days, I noticed that many drivers were comfortably speeding and going in the wrong lane. Maybe they think there is no cold penalty camera system yet.

Human life is the most valuable, so we cannot ignore it just because there are no cameras or we have not been caught or punished. Therefore, when traveling on the highway, it is necessary to understand the language of the highway and need to upgrade both the driver's awareness and knowledge level. Although driver awareness cannot solve infrastructure problems, it will help minimize the damage that can be caused by current infrastructure limitations.
