8 Key Insights into Left-Hand Turn Collision Accidents in Arizona

Left-Hand Turn Collision: Who Caused the Accident?

What Cyclists Need to Know After Collisions Involving Left-Hand Turns in Arizona

In December 2022, a young family of three was driving in Phoenix in the middle of the afternoon. The mother, a 20-year-old who had recently given birth, was behind the wheel. When she turned left at an intersection, she didn’t see the pickup truck barreling toward her. The truck’s driver didn’t see her either. He would subsequently be arrested for DUI, but not before slamming into the side of the family’s car. The father and daughter were killed in the crash, and the mother succumbed to her injuries a week later.

While this left-hand turn collision didn’t involve a cyclist, it is one of the most tragic cases in recent memory. It also highlights some of the challenges involved with left-hand turn accidents. While it appears that the driver of the pickup truck may have been drunk at 3:45 in the afternoon, there is no indication of who had the right of way, whether the intersection had adequate visibility, or whether any of a variety of other potential factors were involved in the accident.

We’re sure the police addressed these issues during their investigation, but the details in news stories covering accidents like these tend to be fairly scant.

Just like drivers and passengers, cyclists face very high risks when making left-hand turns. While all drivers should obey the law and pay attention to the task at hand, it is clear that far too many do not. As a result, close calls involving left-hand turn collision are extremely common. Sadly, serious and fatal accidents involving left-hand turn collision are common as well.

What Are the Laws on Left-Hand Turn Collision in Arizona?

“I commute to work on my bike. While I can stay on the right-hand side of the road most of the time, there is one left-hand turn I need to make my way home. It’s always made me nervous, but I never had an accident—until last week. I waited for the green arrow like I always do and started my turn. But, while I was in the intersection, a car came out of nowhere from the opposite direction. It ran the light and, luckily I guess, just clipped my back tire. The impact still sent me flying, and I am still in the hospital recovering.”

“Can I sue the driver? I clearly had the right of way, and as far as I know cyclists can use the traffic lanes in Arizona.”

Cyclists can use the traffic lanes in Arizona. In fact, the law makes clear that cyclists have the exact same rights as drivers in most cases. While cyclists are supposed to ride on the right-hand side of their lane when they can, they need to get over to the left in order to make left-hand turns.

Quite frankly, in this hypothetical scenario, the cyclist is lucky to have survived. If the driver had been going just a few miles per hour faster, he may have T-boned the cyclist—which would have been a much worse collision. In these types of left-hand turn collision, cyclists often get thrown off of their bikes into the street, and they get run over in many cases.

While there seems to be a fair amount of confusion about the left-hand turn collision laws in Arizona, the Arizona Revised Statutes are pretty clear.

1. Arizona’s Left-Hand Turn Collision Laws

For example, Section 28-645(A)(3)(a) states, “vehicular traffic facing a steady red signal alone shall stop before entering the intersection and shall remain standing until an indication to proceed is shown.” This means that drivers have to stop at all red lights, and they cannot proceed through the intersection until it is their turn. If a driver runs a red light and hits a cyclist who is making a left-hand turn, the driver is clearly at fault in this scenario.

Similarly, Section 28-645(A)(1)(a) states, “[v]ehicular traffic facing a green signal . . . shall yield the right-of-way to other vehicles and to pedestrians lawfully within the intersection or an adjacent crosswalk at the time the signal is exhibited.” This means that even if a driver has a green light, the driver still has a duty to yield to cyclists who are lawfully making left-hand turns.

Another relevant law is Section 28-772 of the Arizona Revised Statutes: “The driver of a vehicle within an intersection intending to turn to the left shall yield the right-of-way to a vehicle that is approaching from the opposite direction and that is within the intersection or so close to the intersection as to constitute an immediate hazard.” This means that when an intersection isn’t controlled by a traffic light, cyclists have the right to make a left-hand turn as long as there are no approaching cars that are so close as to present an “immediate hazard.”

2. Break It Down For Me—What Do Cyclists Need to Know?

If you find the language in the Arizona statutes confusing, you are not alone. Here is a breakdown of what cyclists need to know about the state’s left-hand turn collision laws:

  • Left-Hand Turn Collision at Intersections With Stop Lights – If a cyclist has a green light to make a left-hand turn, the cyclist has the absolute right to make the turn. There is no excuse for running a red light, and drivers who have green lights must yield to cyclists who are already lawfully in the intersection.
  • LeftHand Turn Collision at Uncontrolled Intersections – At uncontrolled intersections, cyclists can make left-hand turns as long as it appears safe to do so. If a speeding driver comes around a bend or a reckless driver enters the intersection unexpectedly, the cyclist is not at fault as long as he or she made a reasonable decision.

All cyclists can do is follow the law and use their best judgment. If they do these two things and they still get hit by a driver who is drunk, being reckless, or not paying attention, there is nothing they can do other than seek to hold the driver accountable.

What if a Cyclist with the Right of Way Hits a Driver Who Made an Illegal Left-Hand Turn?

“I was riding my bike in the hills outside of Phoenix. I was on a downhill stretch, and my GPS head unit said I was going about 35 mph—still 10 mph below the speed limit. As I approached an area with a left-hand turn lane on the other side, I saw a car with its blinker on, but I assumed they would see me coming and wait.”

“As it turned out, they didn’t. Just as I got there, the driver turned left in front of me. I grabbed my brakes, but there was no way I was going to stop. I slammed into the side of their car, destroyed my bike, and suffered several injuries in the crash.”

“I know I technically hit the car, but wasn’t the driver at fault? I was going straight on a clear day, and the driver made a left-hand turn in front of me for no reason.”

This is another common scenario for left-hand turn collisions, and it is one that can be extremely scary for cyclists. You’re riding along, enjoying the day, and all of a sudden a driver puts you in a position where you have no way to avoid a collision.

In this scenario, the law is also clearly on your side. Let’s look back at Section 28-772. If we focus only on the relevant language, it states:

“The driver of a vehicle . . . intending to turn to the left shall yield the right-of-way to a vehicle that is approaching from the opposite direction and . . . so close to the intersection as to constitute an immediate hazard.”

While this law specifically references “vehicles,” the obligation to yield applies equally when it is a bicycle—rather than a car, truck, or SUV—that is approaching from the opposite direction. So, if you are riding your bike and a driver dangerously turns left as you are approaching, the driver is responsible in the event of a collision. This is true whether the driver hits you as you pass or you run into the side of the driver’s vehicle.

8 Key Insights Proving the Driver was At Fault in a Left-Hand Turn Collision with Bicycle

Since determining fault for a left-hand turn collision is often a matter of timing, proving that a negligent driver is responsible for your injuries (or your loved one’s wrongful death) presents some unique challenges. But, while it may be challenging, it is not impossible. At Phoenix Accident and Injury Law Firm, we have extensive experience handling these types of cases, and we have helped many cyclists and families conclusively prove their legal rights.

As with any type of serious or fatal bicycle accident, when dealing with an accident involving a left-hand turn collision, it is important to investigate the accident as soon as possible. When investigating these accidents, we typically seek to collect evidence such as:

  1. Forensic Evidence from the Crash Site – Skid marks (from both the bicycle and the car) can help prove who was at fault in a left-hand turn collision. These markings on the road can show speed and direction of travel, and they can show precisely where the accident occurred. These are all factors that are critical for establishing liability after a bicycle accident.
  2. Vehicle Damage – Even though vehicles are much bigger and stronger than bicycles (and cyclists), left-hand turn collision will often result in vehicle damage. If the vehicle was damaged, the location of the damage can help with proving that the driver was at fault.
  3. Bicycle Damage – The location and extent of the damage to the rider’s bicycle can also help with proving fault. For example, if the damage to your bike shows that you got hit from the side, this will point toward the driver’s liability (though, as discussed above, cyclists will often be unable to avoid head-on collisions as well).
  4. The Bicycle Rider’s Injuries – Likewise, the nature and extent of a rider’s injuries can assist with proving liability in many cases. Different types of injuries are consistent with different types of collisions, and the severity of a rider’s injuries can speak to the speed at which the driver was traveling at the time of impact.
  5. Traffic Camera Footage – Since left-hand turn collision generally occur at intersections, they will often be caught on video. If there is traffic camera footage of your (or your loved one’s) bicycle accident, the footage could conclusively establish the driver’s liability.
  6. Eye-Witness Testimony – Similarly, the fact that these left-hand turn collision accidents often occur in high-traffic areas means that there will be witnesses in many cases. If any witnesses can testify as to what happened, their testimony could be strong evidence in support of your (or your family’s) claim for financial compensation.
  7. Social Media Posts – You would be surprised how many people admit to causing accidents on social media. If the driver posts a photo of the accident with the caption, “OMG, I can’t believe what I just did,” this is evidence that our lawyers can use in settlement negotiations (and in court, if necessary).
  8. Phone Records, Receipts, and Other Documents – In many cases, our lawyers specializing in left-hand turn collision will be able to secure documents that point toward the driver’s liability (or potentially a third party’s liability) as well. For example, if the driver was talking on the phone or texting, we can obtain his or her phone records to prove it. Or, if the driver was drunk behind the wheel, we can work to obtain receipts from the bar or restaurant where the driver was drinking before the crash.

I was in an accident that resulted in getting whiplash and a concussion. I contacted Phoenix Accident and Injury Law Firm that day. Everyone was helpful (Rhea, Karissa, and Jeff) from the very beginning to the very end. They sent me to a physical therapy location that was pretty far away but the doctor and physical therapist were very kind so I did make the trek. They handled all aspects of my case in a timely manner and answered all my questions. They got the max amount possible, and from that, paid the medical bills and took their fair cut. I would not hesitate to recommend them to family or friends.

I would give ten stars if I could. This law firm is about as professional and friendly as it gets!! They stayed in constant contact with me and answered every question I had. I got a settlement that was higher than I expected and will definitely use this law firm again. I highly recommend hiring them to handle your legal issues!!
