55 SPEED LIMIT

Cars and other vehicles can travel much faster than the speeds for which highways are designed. They can travel much faster than drivers can safely stop them in an emergency. High travel speeds lead to more frequent crashes and more serious crash injuries--the higher the speed the worse the problem. Early in 1974, speed limits of 55 mph were enacted in all states to save gasoline during an acute shortage. They've had the benefit, too, of reducing deaths and injuries. This edition of IIHS Facts addresses the 55 mph speed limit.
