The closure was reported at milepost 316 on eastbound I-10. ADOT said the crash prompted a full shutdown of the eastbound lanes and gave no estimate for when the road would reopen.

Frequently Asked Questions
How are fatal crashes like this one investigated?
Agencies such as ADOT and state or local police typically document the scene, collect physical evidence, and interview any witnesses before determining a sequence of events. On interstates, this often requires closing lanes for several hours.
How long do these investigations usually take?
Initial findings can take days, while a full report, including contributing factors, often takes weeks or longer depending on the complexity of the crash and whether a specialized reconstruction team is involved.
Does impairment play a role in highway fatal crashes?
It can, but investigators don't confirm impairment until toxicology results and interviews are complete. It should never be assumed before an official finding.
Where do fatal crashes happen most often?
They are common on rural interstate stretches with higher speeds, like the I-10 corridor between Tucson and the New Mexico line, where limited access points can also slow emergency response.
What to Do After a Car Accident in Benson, AZ
If you're ever involved in a highway crash near Benson, move to a safe location if possible and call 911 right away. Stay as still as you can until paramedics check you over, since some injuries, like whiplash or internal bleeding, don't show symptoms immediately. Exchange information with other drivers if you're able, and take photos of the scene if it's safe to do so. Follow any detour instructions from ADOT or law enforcement, and keep a copy of the official crash report for your records once it's released. Reach out to your insurance company promptly to begin the claims process.
