Speeding Laws in Arizona

According to the Arizona Revised Statute ARIZ § 28-701(A) & (D), also called the basic speed rule, a person shall not drive a vehicle at a speed greater than the reasonable and prudent speed, that may cause a potential hazard to others under the conditions.

Over speeding in Arizona

Anyone found over speeding in Arizona or breaking the law will have to face a number of consequences. A first time offender who exceeds the speed limit will have to face a fine of no more than $250 and their driver’s license will be suspended for no more than one year.

Driving recklessly in Arizona

Anyone found driving recklessly in Arizona will also have to face a number of consequences. A first time offender who drives recklessly will have to pay a fine of no more than $750. They may also be sentenced to no more than 120 days in jail and their driver’s license will be suspended for up to 90 days.

Exceeding a posted speed limit of 55 mph

Most Arizona highways have a posted maximum speed limit of 55 mph. If a driver exceeds this limit, but was driving at a speed less than 65 mph, they will be subject to a fine of no more than $15. The offender may also have to pay assessments which can be less than 60% of the fine imposed.

The offense of exceeding the posted speed limit is considered a civil traffic violation and is not to be used to establish motor vehicle insurance rates. If the driver exceeds the 55mph speed limit by more than 65 mph, then the regular sanctions for a speeding offense will apply, which are ARIZ § § 12-116.01, 12-116.02 and 28-702.01(A) & (C)

Statutory speed limits in Arizona

The following speed limits have been defined under Arizona law under the statute:

  • 15 mph when approaching a school crossing
  • 25 mph when in a business or residential district
  • 65 mph on interstate highways outside of urban areas that have a population of more than 50,000
  • 65 mph for vehicles that weigh more than 26,000 lbs. This excludes any vehicles that are designed to carry 16 or more people, including the driver
  • 65 mph for vehicles that draw a pole trainer that weighs more than 6,000 lbs.

Possible defenses used in over speeding cases

A number of possible defenses can be used for over speeding in Arizona, the three most commonly used are:

  • Attacking how the officer determined your speed. For this, you must discover the method the officer used to cite you and learn how you can attack that particular method.
  • Claiming that you had to take care of an emergency to prevent harm or damage to yourself or to someone else which forced you to exceed the speed limit.
  • Claiming that it was not you who was over speeding but the officer mistook you for another car. The officer may have made a mistake with so many similar looking cars driving on the road and picked you wrongly in the end.

Arizona Point system

A driver who accumulates more than 8 points on their license within 12 months may have to face the following:

  • Have their driver’s license suspended for up to 1 year or
  • May be required to attend a traffic education and training course

The following points are assessed for speeding and speed related violations in Arizona:

  • 2 points for a violation of any provision of § 28-701
  • 8 points for either reckless driving or racing on the highways
  • 2 points for any other violation

Arizona speeding laws are defined under AAC § 17-4-506 (via ’28-202(A)) & § 28-3315(A).

brian sloan on the cover of attorney at law magazine

“I am one of only a handful of Phoenix DUI Lawyers that focuses solely on DUI Defense representation.”

I have spent my entire career focused on Arizona DUI Defense representation, having personally defended over 4,200+ DUI clients in the past 19+ years.

If you’re looking for a divorce attorney, tax attorney, or civil attorney, I can comfortably say, "I’m not the one for you."

Coming up with traditional, as well as outside-the-box motions and defenses for my clients, often with good results, is the hallmark of my practice.

Lawyers that say they are "aggressive" or "will fight for you" are a dime a dozen. They use these phrases because they think people want to hear them. Being "aggressive" isn’t the same as being good and is often used to put on a show to hide the fact that they aren’t doing anything meaningful for the client.

The same is true for the lawyers claiming to do DUI Defense, Criminal Cases, Accident Cases, and Divorces. A Jack-of-all-Trades is a master of none! By handling all sorts of cases, they take away from their ability to truly focus on DUIs, and keep up to date on the latest changes in Phoenix DUI Defense Representation.

What I offer is intelligent, quality DUI Defense at an exceptional price.

I have not only taught other lawyers how to do DUI Defense Representation at statewide seminars, but I produced DUI Legal Guides used by defense lawyers across Arizona.

I am one of Arizona's most award-winning DUI Defense Lawyers, recognized nationally, including in a 2022 issue of USA Today.

There are no other private DUI Defense Lawyers in Arizona that have personally defended more DUI cases than I have. And as a bonus, I offer a flat rate for my legal services without any hidden charges. This guarantees that I offer some of the most competitive rates among all Arizona DUI Attorneys, while being the preeminent leader in the field of DUI Defense Representation.

Over the years, countless people have come to me after discovering that their first lawyer made a mistake, gave them false hope or false promises, or simply took their money and didn't do much to advance their case. And you would be surprised at how often this happens.

So, instead of wasting time and money on the wrong DUI Defense Attorney, do yourself a favor and get the proven and documented best DUI Lawyer in Phoenix and the surrounding areas of Maricopa County.

You can reach me on my cell phone: 480-720-7839.
