As speed increases, vehicles respond more quickly to steering and more slowly to braking. Inexperienced drivers may make abrupt changes, which can make the vehicle go out of control. It takes time to learn to how to handle a vehicle at high speeds. High-speed crashes have higher crash forces and are more likely to result in severe injuries.
Recommendation for Parents:
Limit your teen's unsupervised driving to familiar, lower speed roads for the initial months of licensure, and gradually allow unsupervised driving on higher speed roads as your teen gains more experience.
