Getting arrested for boating DUI on Lake Havasu can ruin your entire season. Arizona takes operating under the influence seriously, and Mohave County prosecutors do not go easy on boat operators just because you are on vacation.
If you were arrested for boating DUI, you are facing criminal charges under ARS 5-395 that carry the same penalties as a regular DUI, plus the risk of losing your boating privileges on the Colorado River.
Matthew Lopez Law defends boat operators throughout Lake Havasu and Mohave County. We offer affordable payment plans, and we can start your case with very little money down. Call us 24/7 for a free consultation.
What is Boating DUI Under Arizona Law?
Arizona law makes it illegal to operate any watercraft while impaired by alcohol or drugs.
Under ARS 5-395, you can be arrested for boating under the influence if you are operating a motorboat, jet ski, sailboat, or any other vessel on Lake Havasu with a blood alcohol concentration of 0.08 or higher.
You can also be charged if you are impaired to the slightest degree, even if your BAC is below the legal limit.
Boating DUI carries the same penalties as a standard DUI in Arizona. That means:
- Jail time
- Fines
- Alcohol classes
- Criminal record
If your BAC was 0.15 or higher, you are facing an Extreme DUI charge. If it was 0.20 or above, that is a Super Extreme DUI, which comes with mandatory jail time even on a first offense.

Aggravated Boating DUI (Felony)

- Up to 2 years in prison
- Loss of voting rights and gun rights
- Permanent felony record
How Boating DUI Arrests Happen on Lake Havasu
Most boating DUI arrests on Lake Havasu happen during spring break and summer weekends when Mohave County Sheriff’s deputies and Arizona Game and Fish officers are patrolling the lake.
They are looking for:
- Reckless operation
- Equipment violations
- Any reason to make a stop
Once they pull you over, they are watching for signs of impairment:
- Slurred speech
- Bloodshot eyes
- Smell of alcohol
- Any admission that you have been drinking
If they suspect impairment, they will ask you to perform field sobriety tests. These are the same tests used in roadside DUI stops—walk and turn, one leg stand, horizontal gaze nystagmus.
Here is the problem:
These tests were not designed to be performed on a boat dock.
You have been on the water all day. Your balance is already off. You are being asked to perform coordination tests in swim trunks and sandals on a moving surface.
These tests are not reliable indicators of impairment in this context, and our lawyers challenge them aggressively.
Can You Refuse a Breath or Blood Test?
Arizona has implied consent laws.
By operating a boat in Arizona, you have agreed to chemical testing if you are arrested for boating DUI.
If you refuse the test, you face:
- Automatic driver’s license suspension (even though the arrest happened on a boat)
- The officer can get a warrant and force a blood draw
- Your refusal can be used against you in court
In most cases, it is better to take the test and let us challenge the results later.
Defenses to Boating DUI Charges
We defend boating DUI cases by attacking every part of the prosecution’s case.
No Reasonable Suspicion to Stop
Officers need reasonable suspicion to pull you over on the water, just like they do on the road.
If they stopped you without a valid reason, any evidence they gathered after the stop can be suppressed.
Field Sobriety Tests Are Unreliable on a Boat Dock
The National Highway Traffic Safety Administration designed these tests to be performed on flat, dry pavement.
They do not account for:
- Being on the water all day
- Wearing inappropriate footwear
- Natural lack of balance from spending hours on a moving boat
We challenge the validity of these tests in every boating DUI case.
Breathalyzer and Blood Test Errors
Breathalyzers have to be properly calibrated and maintained. Officers have to be trained in how to use them.
If there were problems with the machine or the officer’s certification, the results can be excluded.
Blood tests have to be:
- Drawn by a qualified person
- Stored properly
- Processed according to strict protocols
If the chain of custody was broken or the sample was mishandled, we argue that the results are unreliable.
Rising BAC Defense
If you had a drink just before getting back on your boat, your BAC might have been under the legal limit while you were actually operating, but over the limit by the time you were tested an hour later.
This is called the rising BAC defense, and it is particularly effective in boating cases where there is often a significant delay between the stop and the test.
What to Do If You Are Arrested for Boating DUI
If you are arrested for boating DUI on Lake Havasu, the first thing you should do is remain silent.
Do not answer questions about:
- How much you have had to drink
- Where you have been
- What you were doing
Officers are gathering evidence against you. Anything you say will be used in court.
Politely decline to answer questions and ask to speak with a lawyer.
After You Are Released
Call us as soon as possible.
The sooner we get involved, the more options we have to fight your case. We can often negotiate with prosecutors to get charges reduced or dismissed before your case goes to trial.
Do not wait. Boating DUI cases move quickly, and there are deadlines for challenging evidence and filing motions.
Why Lake Havasu Boating DUI Cases Are Different
Boating DUI cases in Lake Havasu have unique factors that do not apply to regular DUI arrests.
Longer Time Between Stop and Test
Officers have to bring you back to shore, transport you to a testing facility, and wait for a certified person to administer the test.
During that time, your BAC can change significantly.
If you were right at the legal limit while operating, you might be well over it by the time you are tested an hour later.
Sun Exposure Creates Signs of “Impairment”
Spending all day in the sun causes:
- Red, watery eyes
- Dehydration (which causes slurred speech)
- Unsteady balance
Officers are trained to look for these signs as evidence of impairment, but they are often just the result of a day on the lake.
Many Cases Involve Out-of-State Visitors
If you are from another state, you need a lawyer who can navigate the Arizona criminal court system on your behalf and minimize the number of times you have to travel back to Mohave County for court appearances.
We handle as much as possible without requiring you to be present, and we work to resolve your case quickly.
Will a Boating DUI Suspend My Driver’s License?
Yes.
Even though the offense happened on a boat, Arizona will suspend your driver’s license.
A boating DUI is treated the same as a regular DUI under state law, and the Motor Vehicle Division will take action against your driving privileges.
You have 15 days to request a hearing
If you miss that deadline, you lose the right to challenge the administrative suspension.
Call us immediately so we can protect your rights from the start.
