Official Regional Data
Phoenix Metro Intersection Crash Data
The Maricopa Association of Governments (MAG) publishes a list of the 100 intersections in the region with the highest crash risk, based on 2018–2022 crash data. This page presents MAG's list exactly as published — their rankings, their crash counts, their scores — and explains what a listed location can mean if you were injured in a crash there.
Marker size and brightness follow MAG's Final Score (ISS). Larger, brighter markers = higher MAG-ranked crash risk.

How MAG calculates this ranking
MAG's Intersection Safety Score (ISS) weighs three factors: 25% crash frequency, 50% crash severity, and 25% crash type. Severity carries the most weight, which is why some intersections rank high with fewer total crashes.

What this data can mean for an injury case
Public entity responsibility and a much shorter deadline. MAG publishes this ranking so cities and regional agencies can identify intersections that need safety improvements. When a serious crash happens at a location with a documented, multi-year history of severe crashes, one question an attorney may evaluate is whether roadway design, signal timing, or maintenance played a role — and whether a city, county, or state agency shares responsibility. Claims against Arizona public entities follow a much shorter timeline: under A.R.S. § 12-821.01, a notice of claim must be filed within 180 days. That is months shorter than the two-year deadline that applies to most Arizona injury claims under A.R.S. § 12-542.
When the insurance company blames you. Arizona follows pure comparative fault under A.R.S. § 12-2505: you can recover compensation even if you were partly at fault, with your recovery reduced by your percentage of responsibility. When an insurer argues you were careless, the documented crash history of the location is part of the context an attorney examines.
The location itself is evidence. Where an intersection appears on this list, what MAG's scores show about severity patterns there, and what the intersection looked like on the day of your crash can all matter to how a claim is investigated.
If your crash happened at one of these intersections
- Get medical care first, even if you feel fine. Some serious injuries take hours or days to show symptoms.
- Request the police crash report. It documents the location, signal status, and the officer's observations.
- Photograph the scene if it is safe: signals, signs, lane markings, skid marks, and vehicle positions.
- Check this page. If your intersection appears on MAG's list, tell your attorney — the location's documented history may be relevant to your claim.
- Do not give a recorded statement to the other driver's insurance company before speaking with an attorney.
- Watch the deadlines. Most Arizona injury claims: two years (A.R.S. § 12-542). If a government entity may be involved: 180 days to file a notice of claim (A.R.S. § 12-821.01).
Frequently asked questions
What are the most dangerous intersections in Phoenix?
According to MAG's crash-risk ranking using 2018–2022 data, the highest-ranked intersection in the region is 67th Ave & McDowell Rd in Phoenix, followed by 51st Ave & Camelback Rd in Glendale and 19th Ave & Peoria Ave in Phoenix. MAG's ranking gives the most weight to crash severity — 50% of the score.
Which Phoenix-area intersection has the most crashes?
In MAG's 2018–2022 data, 99th Ave & Lower Buckeye Rd in Phoenix recorded 429 crashes — the highest total on the list. It ranks 10th on overall crash risk because MAG's score weighs severity above raw crash counts.
Why do some intersections rank high with fewer crashes?
MAG's Intersection Safety Score is 25% crash frequency, 50% crash severity, and 25% crash type. An intersection with fewer crashes but more serious injuries can outrank one with many minor collisions. Cave Creek Rd & Sweetwater Ave ranks 7th with 46 crashes because it has the region's highest severity score.
Does it matter for my case that my crash happened at a listed intersection?
It may. A documented history of severe crashes can be relevant when an attorney evaluates whether roadway conditions played a role, whether a public entity shares responsibility, and how to respond if an insurer blames you. Every case is different — an attorney can evaluate what the location history means for yours.
Can I recover compensation if I was partly at fault?
Yes. Arizona's pure comparative fault rule (A.R.S. § 12-2505) allows recovery even if you share fault; your compensation is reduced by your percentage of responsibility.
How long do I have to file an injury claim in Arizona?
Generally two years from the date of injury under A.R.S. § 12-542. If your claim involves a city, county, or state entity — for example, a claim about roadway design or signals — a notice of claim must be filed within 180 days under A.R.S. § 12-821.01. Missing these deadlines can permanently bar a claim.
