Most of the accidents take place due to high speeds because stopping distance increases with the speed greatly. As an example, if you can stop your car completely within 25 meters at 30 Km/h, even you cannot stop your car within 100 meters (25 x 4) at the speed 120 Km/h (30 x 4). You need at least 150 meters for a normal car. This means that stopping distance is not proportional to the speed! Therefore it is very important to drive cars in moderate speed. High speed also decreases the fuel efficiency. From following plot you may easy to understand that a car gives its maximum mileage in moderate speeds (For this particular car at 40 Mph)
Next thing is driving after using liquors. Because after taking liquors, reaction time of human decreases and takes lot of time for driving actions. As example, Driver cannot stop the car rapidly to avoid an accident because he takes lot of time to get the decision of hitting the brakes!
So it is important to drive without having liquor, in moderate speeds wearing the seat belts. Seat belts are very important because if your car has air bags, they will also not work in case of an accident if you don’t wear your seat belts properly.
