I think this suggestion is very necessary, because in our current driving test, we basically pay attention to the investigation of our driving skills and our civilized driving behavior. It can be said that this kind of investigation has been going on for a long time. However, we found a problem. There are more and more vehicles on the road now, but many times, our drivers don't know what to do after our vehicles have an accident, especially some dangerous traffic accidents. We can only wait for our ambulance personnel to appear on the scene, but when we need to know, the patient's first aid time is very limited, which may delay the rescue time when our ambulance arrives. If our accident place is a very remote place, and there is no cell phone signal in this place, it is a very dangerous situation for us, because at this time, if our wounded person is in a coma or shock, we can't rescue her in time, so such behavior is very dangerous for us. So I think it is very necessary for our drivers to learn such skills, at least to provide emergency rescue for the wounded when we have an accident, and also to help those in need in time on the road in the future. This is a very necessary measure. But now many of our drivers pay attention to the driving skills on the road and seldom pay attention to our first aid knowledge. I think this is a big disadvantage for our drivers. For us, everyone's life is only once, and everyone's life should be respected, so what we should do most is to drive carefully on the road and try to avoid accidents. In many cases, we need to learn some knowledge of cardiopulmonary resuscitation, because such knowledge is very necessary in an emergency.
