 And speed contributes to, what, the majority of crashes, or what percentage are we talking about? It's about a third of all crashes. And what we see with people who speed, and again, speed excessively, is that they take other risks. About half of the people who are killed in speeding crashes also aren't wearing a seatbelt. They may be distracted by a cell phone. They may be impaired by alcohol or drugs. So there are a host of things going on, but about a third of all traffic deaths every year are speed-related.
