What causes car deaths and how to limit them

Perhaps the biggest reason why we don’t see more fatal crashes on freeways is that there are no intersections on them (with a few exceptions). In fact, there are more drivers killed in intersections (20%) than on freeways.

After accounting for freeways (18%) and intersections and junctions (20%), we’re still left with more than 60% of drivers killed in automotive accidents left accounted for.

It turns out that drivers killed on rural roads with 2 lanes (i.e., one lane in each direction divided by a double yellow line) accounts for a staggering 38% of total mortality. This number would actually be higher, except to keep the three categories we have mutually exclusive, we backed out any intersection-related driver deaths on these roads and any killed on 2-lane rural roads that were classified as “freeway.” So, to recap, 3 of out every 4 deaths in a car occur on the freeway, at an intersection/junction, or on a rural road with a single lane in each direction.

And:

In drivers killed on 2-lane rural roads, 50% involved a driver not wearing a seat belt. Close to 40% have alcohol in their system and nearly 90% of these drivers were over the legal limit of 0.08 g/dL. About one-third involved speeding, and 16% did not have a valid driver’s license.
