What and How can we make roads and cars more safe?

we can make roads and cars more safe by using the equipments of good quality and taking care of things and using all our efforts to make it by having a feeling that no one suffer afterwards , and having a great idea of the things which we need like the machine's and the car engines and the other equipments and if the road is made good then the people who have just got the approval for driving wouldn't face so much problem regarding the roads ,while making roads we should think about the safety's also as if we are making in hilly areas there the construction of roads are very difficult so we should keep in mind that we should work very focused for not getting in trouble and also by insuring that while every turn there are barriers or sign boards for the people safety's for making them alert and driving slow .
