We fear about accidents, right? What an awful nightmare if there’s accident happen to someone. Well the factors of accidents can be various factors, for example: the negligence of people, impatience of the drivers, and so many factors that can create an accident. But most of all it from ourselves, we have to be careful if we’re still on the street. We have to see where we are going, not to be in a hurry when we drive a car and watch surrounding of us.

Roads sometimes do not have sufficient safety signs for the roads safety. For instant: traffic cones, traffic cones are needed for the sign that the road is still being repaired and there’re workers passing across the street. So by this, the drivers can be more careful drive their cars so that there will not be a collision happens. I’m really sure everyone has warning flags, it’s used when there’s problem with your car, you can place warning flags rather far from your car is placed in order the other drivers can see your car. For policeman, they have to place traffic barricade to secure the area that are contaminated. There’re two types of barricade, the custom barricade and the barricade with lighting that can be useful in the night where there’s not enough light to illuminate the street.
