Facts come from the body that keeps them
Each rule or figure on this site comes from the body that makes it or keeps it. Time limits, the fault rule and insurance minimums come from the Arizona Revised Statutes on azleg.gov. Report steps and fees come from the Tucson Police Department, the Pima County Sheriff’s Department and the Arizona Department of Public Safety. Court addresses come from the Arizona Superior Court in Pima County and the Pima County Consolidated Justice Court. The trauma center list comes from the Arizona Department of Health Services.
We cite the statute beside the sentence that relies on it and link agency pages where readers can act on them. A news story or a law firm page can point us to a topic, but we confirm the fact with the official source before it goes on the page. If we cannot confirm a fact, we leave it out.
Live news stays with the agencies
Many readers arrive looking for a crash that just happened. We do not rewrite those reports. The incident desk sends readers to AZ511, Tucson Police, the Pima County Sheriff and DPS, which publish the details first and correct them when they change. We check that each link still works whenever we update the page.
How the county record is counted
The county record uses the Fatality Analysis Reporting System from the National Highway Traffic Safety Administration. We download the yearly files, keep the crashes coded to Pima County and add up the deaths. The years 2020 to 2023 come from final files. The year 2024 comes from the first annual file, so it can still change, and the chart marks it. Road totals merge spelling and direction variants of one road and leave out ramps and frontage roads. We do not estimate figures the data does not hold.
Updates and corrections
When a law, a fee or a request process changes, we update the page and its date. If a correction changes what a reader should do, we add a short dated note. To report a problem, use the corrections page. For a callback about your own crash, use the free case review.
