Anyone who operates a vehicle on a roadway or highway cannot do so if they have a blood or breath alcohol content of at least 0.08 percent or if they are impaired. For people who ride mopeds, golf carts or motorcycles, Florida’s DUI law is applicable to you.
But what happens if you are on a lawnmower or riding a bicycle while intoxicated? According to Florida law, you can be arrested and convicted of DUI under these circumstances and punished just as if you were driving an automobile.
The Florida courts have broadly interpreted the DUI laws to include anyone riding a bicycle or lawn mower. The term "driver" referenced in the Florida DUI statutes means any person who drives or is in actual physical control of a “vehicle” on the road. "Vehicle" is defined as any device by which a person may be transported upon the roadways of Florida. Based on these broad definitions, a person driving a bicycle or lawnmower is subject to Florida’s DUI laws.
In summary, you cannot escape prosecution for a DUI merely because you are driving or riding a vehicle that is not a car.
