Connecticut DUI and BUI in 2026: What the New Reciprocal Law Means for You
Connecticut DUI and BUI charges now carry consequences that cross between road and water. Under Public Act 25-159, signed into law in 2025 and in full effect for the 2026 season, a conviction for boating under the influence can now suspend your driver’s license — and a DUI conviction on land can cost you your Safe Boating Certificate. If you spend time on Connecticut’s waterways and roads, you need to understand what changed and what it means for your defense.
What Changed Under Public Act 25-159
Before this law, Connecticut DUI and BUI charges operated in separate silos. A boating conviction stayed on the water side. A driving conviction stayed on the road side. Prosecutors and the DMV couldn’t touch your boating privileges based on a driving offense — and vice versa.
That separation is gone. The new law creates a reciprocal enforcement structure:
- A DUI conviction on land may result in suspension of your Safe Boating Certificate
- A BUI conviction on water may result in suspension of your Connecticut driver’s license
This affects anyone who operates a vessel on Connecticut waters — lakes, rivers, Long Island Sound — and anyone who drives. That’s most of the state. The full text of Public Act 25-159 is publicly available if you want to read it directly.
Why the Law Was Passed
Legislators pointed to a gap in enforcement that allowed repeat impaired operators to keep boating after DUI convictions — and keep driving after BUI convictions. A fatal boat crash in Old Saybrook accelerated the legislative push. The argument was simple: if someone has already shown they’ll operate impaired, the state should have tools to restrict them across both environments.
The Connecticut DEEP and the DMV now coordinate suspensions under this framework. That means when you’re convicted, two agencies are involved — not one.
What the Existing BUI Penalties Look Like
Even before this change, Connecticut BUI charges carried real consequences under CGS § 15-133. Here’s what you’re looking at on the water side:
- First offense: Up to 6 months jail, $500–$1,000 fine, 1-year boating privilege suspension
- Second offense: Up to 2 years jail, $1,000–$4,000 fine, 3-year boating privilege suspension
- Third offense: Up to 3 years jail, $2,000–$8,000 fine, permanent revocation of boating privileges
Now add driver’s license suspension on top of any of those. The stakes doubled with one legislative session.
How DUI Defenses Apply to BUI Cases — and Vice Versa
The legal standards for Connecticut DUI and BUI charges are similar in key ways. Both use the 0.08% BAC threshold for adults. Both allow for charges based on impairment even without a specific BAC reading. Both involve breathalyzer or blood testing — and both involve field testing by officers.
That similarity matters because the same defense angles that work in a DUI case often apply to a BUI case:
- Was the stop or boarding lawful? Officers need grounds to board a vessel and conduct a BUI investigation — just like a traffic stop requires reasonable suspicion.
- Were sobriety tests administered correctly? NHTSA standardized field sobriety tests were designed for land — their reliability on a rocking boat in open water is a real challenge to make in court.
- Was the BAC reading accurate? Equipment calibration, operator certification, and chain of custody all apply on the water exactly as they do on the road.
- Did you have a medical condition? Seasickness, sun exposure, and dehydration can mimic signs of impairment. These are legitimate factors in a BUI defense.

The DMV Hearing Deadline Still Applies
Whether your charge is a DUI or a BUI, the Connecticut DMV administrative hearing deadline is the same: 7 days from your arrest. Miss that window and your license suspension — or boating suspension — becomes automatic. No hearing, no challenge, no second chance at that stage.
That 7-day clock starts the moment you’re charged. Not when you hire an attorney. Not when your court date is set. The day of the arrest. If you’re reading this after a recent charge, the first call you make matters more than most people realize.
