The county number comes from the same FARS files and includes every road. The percentage does not account for traffic, distance or population. The truck and pedestrian numbers count crashes, not people, and involvement does not mean fault.

Where these numbers come from

We used NHTSA's official FARS files for 2022, 2023 and 2024. We counted fatal crashes recorded on I-10 within Maricopa County, then compared that number with all fatal crashes recorded in the county during the same years. You can open the original files below.

What road area does this count cover?

The count covers I-10 anywhere within Maricopa County. It is not limited to one segment or intersection. The county comparison includes every FARS fatal crash in the county during the same years, no matter which road it occurred on. The city names most often recorded for this route were Phoenix, Chandler, Buckeye, but the county line sets the boundary.

How we matched the road name

The matching process checks FARS trafficway field 1 first. It checks field 2 only when field 1 does not match an Interstate or U.S. route. Each crash is counted once.

What this page cannot determine

A corridor count or county share cannot show how any one crash happened, compare traffic risk between roads, or account for vehicle miles, road length or population. It cannot show whether a person was injured, whether a truck or driver was responsible, whether insurance applies or whether anyone has a case. Those questions require the facts and, for a legal conclusion, a licensed attorney.
