Wisconsin Teen Faces DUI Charge After Electric Dirt Bike Chase in Islamorada

A 17-year-old visitor from Wausau, Wisconsin was arrested near Mile Marker 86 in Islamorada on the night of March 27, 2026, after a Monroe County Sheriff's Office pursuit ended with the teenager crashing his electric dirt bike in the Indian Mound subdivision, a blood alcohol concentration of 0.138%, and three criminal charges.

The trouble began around 11:30 p.m. when deputies intercepted two riders traveling without lights in the bicycle lane along U.S. 1. When deputies moved to stop them, both riders hit the throttle and fled into Indian Mound. The teen lost control and wiped out in the subdivision, sustaining minor knee injuries. The second rider escaped and had not been captured as of Saturday.

Deputies took the teen into custody at the scene, seized the electric dirt bike as evidence, and booked him into the Stock Island/Plantation Key facility. He faces charges of driving under the influence, fleeing and eluding law enforcement, and resisting arrest. Officials did not release a booking photo.

His measured BAC of 0.138% is well above Florida's adult legal limit of 0.08% and nearly double the typical threshold used to show impairment among underage drivers. Under Florida's zero tolerance law, any measurable alcohol in the system of a driver under 21 can trigger DUI proceedings. Fleeing and eluding law enforcement is a felony in Florida, carrying penalties that apply regardless of the suspect's age or the type of vehicle involved.

The stretch of U.S. 1 at Mile Marker 86 runs through a dense residential and commercial corridor where the bicycle lane borders active vehicle traffic and neighborhoods like Indian Mound connect directly to the highway. Running a dark, unlit motorized bike through that stretch at midnight with a BAC nearly double the adult legal limit brings the margin for error to nearly zero. The Monroe County Sheriff's Office has stated that riding without lights is illegal and massively increases the likelihood of collisions with vehicles or fixed objects.

Under Florida law, electric dirt bikes and off-road motorcycles are subject to the same traffic rules as any other motor vehicle once on a public road: lights, registration, and compliance with traffic signals are mandatory. Bicycle lanes are not open to motorized vehicles. Riders who want to operate off-road electric bikes legally must do so on private property or designated off-road areas, not on U.S. 1 or any public street. Islamorada has become a recurring enforcement focus as seasonal visitors and spring break travelers increasingly bring electric off-road vehicles to the Keys, making this arrest one of several similar enforcement incidents in Monroe County over the past year.

The investigation remains open. Authorities are still looking for the second rider, and additional charges or arrests are possible.

Take an electric dirt bike or off-road motorcycle onto any public road in the Florida Keys and Florida law treats it as a motor vehicle: operating without lights after dark is a violation, bicycle lanes are off-limits, and refusing a deputy's order to stop converts a traffic encounter into a felony. Under zero tolerance rules, a driver under 21 with any detectable alcohol faces a DUI charge. At 0.138%, the Wausau teen's ride near Mile Marker 86 shows precisely how a late-night sprint on U.S. 1 becomes a criminal case.
