Arizona’s Deadliest Roads and Fatal Accident Statistics

10 Deadliest Road Stretches in Arizona

Drunk Driving Involved in 20.0% of Fatal Accidents

Between 2018 and 2020, 558 out of 2,795 fatal accidents in Arizona involved drunk driving. While a significant portion (20.0%) of deadly crashes in Arizona involved drunk driving in the three years studied, the state saw a 12.8% decrease in car accidents related to drunk driving from 2019 to 2020.

Driving under the influence of even the smallest amount of alcohol can impair the decision-making skills and coordination necessary to navigate the roads safely. A blood alcohol concentration (BAC) of 0.02% is enough to visibly impair your driving, while a BAC of 0.08% means you are considered legally intoxicated.

Getting caught driving under the influence in Arizona can lead to a host of penalties and long-lasting consequences. Even if you don’t cause a fatal accident, the costs of drunk driving could include a suspended driver’s license, fines and possible jail time. It can also make finding affordable car insurance after a DUI difficult, as drivers are required to file for Arizona SR-22 insurance after a DUI, which dramatically increases premiums.

Speeding Is a Factor in 31.3% of Fatal Crashes

Within a three-year period, 875 of Arizona’s deadly accidents involved speeding. Of the three factors MoneyGeek studied, speeding was involved in the highest number of fatal crashes from 2018 to 2020. From 2019 to 2020, the state saw a 9.4% increase in crashes involving speeding, suggesting that this is a growing problem for the state.

Speeding poses dangerous conditions for everyone on the road. Anyone driving over the speed limit is more likely to lose control of their car, increasing the risk of crashing and causing severe injuries to themselves and others. In Arizona, speeding is considered a violation that can incur three points. Accumulating eight or more points in 12 months can lead to driving privilege suspension.

Distracted Driving Contributed to 7.3% of Fatal Accidents

Out of 2,795 fatal accidents that occurred in Arizona between 2018 and 2020, 205 involved distracted driving. To curb distracted driving, the state government enacted a Hands-Off law in April 2020, legally prohibiting drivers from using their phones while driving, with a few exceptions, such as using phones for navigation or reporting a crime. It seems to be working: from 2019 to 2020, Arizona saw a 51% decrease in deadly crashes involving distracted driving. Of the three factors we measured, distracted driving contributed to the smallest number of fatal accidents in the state.

October Had More Fatal Accidents Than Any Other Month

In Arizona, October had the most fatal accidents compared to any other month in the three years analyzed, with 257 crashes. September and May had the next two highest numbers of deadly crashes, with 248 and 243 accidents, respectively.

MoneyGeek found that speeding was the factor most commonly involved in deadly crashes in Arizona; from 2018 to 2020, most fatal accidents involving speeding occurred in April.

Driving Safely Protects You, Others and Your Wallet

From keeping Arizona roadways safe to saving on insurance premiums, practicing safe driving habits has many benefits. Drivers can start driving safely by taking safety courses, practicing defensive driving and ensuring they have auto insurance. After all, even the most cautious drivers can still get into accidents — and a full coverage auto insurance policy is essential to financially protect yourself and your loved ones after a crash. Fortunately, it’s possible to find cheap full coverage auto insurance.

On average, full coverage insurance in Arizona costs $1,284 per year, but rates can change depending on where you live in the state. For instance, drivers pay an average of $1,430 annually for auto insurance in Phoenix; meanwhile, car insurance coverage in Tucson costs $1,167 per year, on average. Between the two cities, the average difference in auto insurance costs per year is $263.

Keep in mind that your rates may be different than these averages. Aside from your specific location within the state, your age, driving record and even your credit score can affect your auto insurance premiums. Make sure to compare quotes to find the cheapest auto insurance companies in your area.
