Can I get a DUI on a golf cart, bicycle, or scooter in Florida?

Yes, and the reason is in the statute's wording.

Florida's DUI statute applies to a person driving or in actual physical control of a vehicle. It does not say motor vehicle. A Florida court addressing bicycles reasoned that the Legislature could have limited the statute to motor vehicles — a definition that excludes bicycles — and instead chose the broader term. The plain language controls.

Golf carts are squarely covered, which is relevant on the Treasure Coast where they're common transportation in a number of communities.

Bicycles are covered under the same reasoning.

The consequences are the same as any other DUI — the same statute, the same penalties, and a license suspension even where the device didn't require a license to operate.

Electric scooters, e-bikes, and similar devices have their own statutory classifications that have been amended in recent years, and the answer there is less settled.
