Boating DUI in Arizona: What Is OUI? Lake Pleasant (ARS 5-395)
Stopped by Lake Patrol at Lake Pleasant? OUI under A.R.S. § 5-395 carries DUI-style jail — and a passenger under fifteen aboard makes it a felony. It cannot suspend your driver license, and the water gives you defenses a road DUI never has. Call us first.

What Is OUI on Lake Pleasant — and How Is It Different From DUI?
A boating DUI — the “Lake Pleasant DUI” — is actually OUI — operating a motorized watercraft under the influence, A.R.S. § 5-395: impaired to the slightest degree, or 0.08+ within two hours, while underway. It carries DUI-style jail — but no license suspension and no interlock, because those laws cover motor vehicles.
The differences from a road DUI matter in both directions. In your favor: the implied-consent license suspension of § 28-1321 and the interlock mandate of § 28-3319 are motor-vehicle statutes — an OUI does not touch your driver license, and passengers on a boat may lawfully drink; the crime belongs only to the operator. Against you: the statute reaches actual physical control of a boat that is underway, the two-hour BAC window mirrors DUI, and juries in these cases hear about crowded coves and kids on tubes. OUI is its own body of law — and it is tried like one.
OUI Penalties: the Tiers Under 5-395.01 and 5-397
First offense (§ 5-395.01): class 1 misdemeanor, ten consecutive days in jail, a fine of at least $250 plus a $500 state assessment — but the court may suspend all but twenty-four consecutive hours if you complete court-ordered alcohol screening, education or treatment, and screening is mandatory in every case. If the State proves reckless endangerment of another person, the floor rises: the court may suspend only all but thirty days. Extreme OUI (§ 5-397): a BAC of 0.15 or more means thirty consecutive days, with a higher tier at 0.20. Second offense within eighty-four months: ninety days, thirty of them consecutive. The structure deliberately mirrors road DUI — but everything rides on programs, timing and tier-fighting, which is defense work.
The Felony Traps on a Family Boat Day
Two facts turn a misdemeanor day on the water into a felony file under A.R.S. § 5-396. First: an OUI or extreme OUI committed while a passenger under fifteen is aboard is aggravated OUI — a class 6 felony. On a lake built for family tubing weekends, that is the single most important sentence in this article. Second: a third OUI within eighty-four months is a class 4 felony — and the lookback counts OUI, extreme OUI and aggravated OUI convictions together. A parent driving the boat after two beers with their twelve-year-old aboard is one breath test away from a felony, and prosecutors charge it exactly that way.
How Lake Pleasant Cases Actually Happen
Lake Pleasant sits inside a Maricopa County regional park, and enforcement belongs to the Maricopa County Sheriff’s Office Lake Patrol — with Game & Fish running its own watercraft enforcement on busy weekends. Stops start as equipment checks, wake-zone violations, or “courtesy inspections” at the no-wake buoys, and the OUI investigation begins the moment a deputy smells alcohol on a boat full of coolers. Cases are cited into the Maricopa County justice courts — for the Lake Pleasant area, typically the Hassayampa Justice Court — not a city court, which changes the prosecutor, the judge and the negotiating culture. Holiday weekends add saturation patrols and OUI checkpoints at the marinas; the Fourth of July and Labor Day dockets fill accordingly.
The Defenses Built Into the Water
“Underway” is an element. Section 5-395 applies to a watercraft that is underway — a boat anchored in a cove, beached on a sandbar or tied to the dock presents a genuine statutory fight that road DUI never offers, and Lake Pleasant days are mostly spent anchored. Who was operating is contestable on a vessel where everyone moves around — unlike a car, a boat has no driver’s seat, and actual-physical-control proof gets thin. Field sobriety tests fail on water: the standardized tests were validated on land; balance-based tests administered on a rocking deck — or after hours of sun, dehydration and “boater’s leg” — are attackable, and our toxicology and blood-test playbook applies unchanged. And the stop itself needs lawful basis: safety-inspection authority on the water is broad but not unlimited, and fishing-expedition boardings are suppression material. If you refused or gave blood, the blood-draw analysis carries over too.

Frequently Asked Questions
Is a Lake Pleasant DUI the same as a regular DUI?
No — on the water it is OUI, operating a motorized watercraft under the influence, charged under A.R.S. § 5-395 in Title 5, not the motor-vehicle DUI statutes. The impairment standards mirror DUI, but the penalties, collateral consequences and defenses are meaningfully different.
Does an OUI suspend your driver’s license?
No. The implied-consent suspension in A.R.S. § 28-1321 and the ignition-interlock requirement in § 28-3319 apply to motor vehicles — an OUI conviction does not suspend your driver license or put an interlock in your car. That difference alone changes how these cases should be negotiated.
Can passengers drink on a boat in Arizona?
The OUI statute targets the person operating or in actual physical control of the watercraft — passengers drinking is not the crime. That is why who was actually at the helm, on a boat where everyone moves around, is one of the most contestable questions in an OUI case.
What is the penalty for a first OUI in Arizona?
Class 1 misdemeanor: ten consecutive days in jail with all but twenty-four hours suspendable on completion of court-ordered screening, education or treatment, plus a $250 minimum fine and a $500 state assessment. Extreme OUI at 0.15 starts at thirty consecutive days.
Is OUI a felony if my kids were on the boat?
It can be — under A.R.S. § 5-396, committing OUI or extreme OUI while a passenger under fifteen is aboard is aggravated OUI, a class 6 felony. A third OUI within eighty-four months is a class 4 felony. These two traps are how family boat days produce felony cases.
Can I get OUI while anchored in a cove?
The statute applies to a watercraft that is underway — a boat at anchor, beached or tied off presents a genuine element fight that has no equivalent in road DUI. Whether the boat was actually underway when deputies arrived is a core defense in cove-party cases.
Do field sobriety tests count on a boat?
They come in, but they are vulnerable — the standardized tests were validated on land, and balance testing on a rocking deck after hours of sun, heat and dehydration measures boating, not impairment. Expert challenge to marine FSTs is standard defense work in OUI cases.
Where do Lake Pleasant OUI cases go to court?
Lake Pleasant sits in a Maricopa County regional park patrolled by the sheriff’s Lake Patrol, so citations are typically filed in the county justice courts for that area rather than a city court — a different prosecutor’s office and negotiating culture than Phoenix or Peoria municipal cases.
