This picture is taken by me this mouth on an important road in Romania. As you can see I'm in my friend’s car and in front of me is a car who had taken a major safety measure at 120 km per hour. A truck  blocked the road without signalling. After 20 seconds we stopped because the automobile in front put on the emergency lights. I saw it because I had less then 70 – 80 km per hour and I succeeded to stop my car. On this road the maximum speed is about 80 km per hour. Even the automobile in front had 120 km per hour, I imagined that my correct speed, which is one of my priorities, helps with the preventive measures than can be taken while driving.
