I worked for a while at a firm where I had access to PennDOT crash data. Though I don't remember specifics I can say with certainty that for every crash with a death, there are easily tens more with injuries and hundreds more with "suspected injuries" (ie. concussion, whiplash, stuff that an EMT would need to check out to be sure of rather than a bone sticking out). And surprisingly, car/bike and car/pedestrian crashes cause injury way more often than death.
