Studies show that if drivers increase the time they have to respond to potential challenges by a half of a second that fifty 50 % of all collisions can be prevented. If they increase their response time by one full second, 80 to 90 % of collisions can be avoided. This includes collisions that result in serious injuries and death. The average driver commits 6 to 8 errors per mile. These errors will cause the driver to have less time to respond to challenges and will be a contributing factor in many collisions. This manual will not only make you aware of these errors, but will show you how choosing an appropriate speed, developing space, using proper visual skills, positioning your vehicle properly and many other factors will give you the time needed to avoid most collisions.
