Introduction
A speeding-related crash is defined as one in which a driver is racing, driving too fast for the conditions, or driving in excess of the posted speed limit. Speeding reduces a driver’s ability to steer safely around curves or objects, reduces the amount of time a driver has to react to a dangerous situation, and extends safe stopping distances.
Designing streets to limit the impact of speeding-related crashes and protecting people even when they make unsafe decisions are part of the Safe Roads and Safe Road Users elements of the United States Department of Transportation’s Safe System Approach. It also includes eliminating speeding and other unsafe behavior through enforcement.
