Proving Fault in Arizona Intersection Collisions: T-Bones, Left Turns, and Red Light Runners

Intersections in cities like Phoenix, Scottsdale, and Chandler are frequent sites for severe car accidents. The physics of an intersection collision, especially T-bones, can cause substantial property damage and personal distress. Determining who is legally at fault requires a detailed look at Arizona's traffic statutes. If you are struggling with a disputed claim, finding a local attorney through our USA Lawyers Directory can help protect your rights.

The Law of Intersections in Arizona

Arizona's right-of-way laws are clearly defined, but applying them to real-world crashes can be complex. Fault is determined by evaluating which driver breached their duty to safely navigate the intersection.

Left-turn yielding accidents (who is at fault if the straight-driver was speeding?)

Under A.R.S. § 28-772, any driver intending to turn left within an intersection must yield the right-of-way to a vehicle approaching from the opposite direction that is close enough to constitute an immediate hazard. Generally, the left-turning driver is presumed at fault in a collision. However, if the straight-traveling driver was excessively speeding or ran a red light, fault may be shared. A thorough investigation into speed limits and skid marks is essential.

Red light runners and traffic camera footage admissibility

When a driver runs a solid red light under A.R.S. § 28-645 and causes a T-bone crash, establishing fault depends heavily on objective video evidence. However, obtaining footage is only the first hurdle; your attorney must ensure the recording is admissible in an Arizona civil court. Under Ariz. R. Evid. 901, the video must be properly authenticated by a witness with personal knowledge-such as a municipal traffic technician or system records custodian-who can testify that the recording system was operating correctly and the footage is an accurate, unaltered representation of the event. To overcome hearsay objections, traffic camera footage is routinely admitted under the public records exception (Ariz. R. Evid. 803(8)). Establishing an unbroken chain of custody is essential to demonstrate that the digital file was not tampered with or corrupted. Because municipal systems frequently overwrite recorded data within days, an attorney must promptly issue a formal spoliation notice and public records request to agencies like the Phoenix Police Department, Phoenix.

Flash-yellow arrow misjudgments

Many Arizona intersections utilize a flashing yellow arrow for left turns. A flashing yellow arrow means you are allowed to turn, but you must first yield to oncoming traffic and pedestrians. Drivers often misjudge the speed of approaching vehicles under these signals. Proving fault in these scenarios typically requires witness statements or dashcam footage to determine exactly when the vehicle entered the intersection.

Multi-car pileups caused by intersection chain reactions

Intersection collisions can easily trigger a chain reaction, involving three or more vehicles. In multi-car pileups, fault can be distributed among several drivers. Investigators will look at the initial point of impact and whether subsequent drivers were following too closely under A.R.S. § 28-730. Determining the sequence of events usually requires accident reconstruction experts.

Proving Fault with Pure Comparative Negligence

Because Arizona applies the rule of pure comparative negligence (A.R.S. § 12-2505), multiple drivers can share the blame for an intersection crash. If you were slightly speeding while another driver ran a stop sign, the court or insurance adjuster may assign 20% fault to you and 80% to the other driver. Your final compensation will be reduced by your percentage of fault. For official civil disputes, filings go through venues like the Maricopa County Superior Court, Phoenix.

Intersection Collision Fault Factors

How Much Does it Cost and How Long Does it Take?

Filing a civil lawsuit for an intersection collision requires a court filing fee, generally ranging from $350 to $367 depending on the county (such as $367.00 in Maricopa County Superior Court). If you need to subpoena traffic camera footage or hire an accident reconstructionist, costs can quickly exceed several thousand dollars. Most personal injury lawyers advance these costs and charge a contingency fee (about 33% to 40%). Depending on the complexity and whether liability is disputed, a claim can take anywhere from 6 months to over 2 years to reach a jury trial or settlement. In addition, under A.R.S. § 12-542, injured drivers face a strict two-year statute of limitations from the date of the crash to file a lawsuit for personal injury and property damage.
