Off-Highway Vehicles
In Florida, both ATVs and OHMs fall under the umbrella of off-highway vehicles (OHVs). What exactly is an OHV? It's defined by state lawmakers as any ATV, two-rider ATV, or OHM meant to be used off the state's roads and highways, and that isn't registered and licensed for highway use.
With that in mind, here's how the state defines ATVs and OHMs:
ATV
This is a motorized vehicle meant for a single rider. It will be 50 inches or less in width, with an unladen dry weight of 1,200 pounds or less. It travels on three or more low-pressure tires, and has a seat that the operator straddles. It also has a handlebar-type steering control.
OHM
An OHM is described as any motor vehicle that travels on 2 or fewer wheels, and is meant for use off of Florida roads and highways. It should also feature a seat for the rider. This doesn't include mopeds or tractors.
ATV/OHM Titling, Registration, and Licensing
All OHVs purchased after July 1, 2002, need to be titled. If you bought your OHV before that and use the vehicle on public lands, your vehicle also needs a title.
The titling fee is $45 for a paper title. Apply for the title at a county tax collector or driver license office. Be sure to complete a title application and follow the procedures listed in the state's OHV titling brochure.
For ATVs, the title decal must be affixed in a clearly visible spot on the left rear quadrant of the vehicle. For OHMs, the decal goes on the left fork leg, in a location easily visible from the left side of the bike. Need to see a picture? The state provides visual guidance in its OHV brochure.
Additional Information
The state Division of Forestry provides additional information on OHV use, including public and private riding areas.
The Laws Regarding: riding unpaved roads.. source
http://www.meldonlaw.com/library/offroad-and-recreational-vehicle-use-and-laws-atvs-rovs-ohms.cfmIn Florida, an ATV, ROV and OHM cannot be operated on a public road, street or highway. The only exception is that they may be operated on a unpaved public roadway where the posted speed limit is less than 35 miles per hour and only during daytime (Fla. Stat. §316.2123).
An ATV, OHM or ROV operator under 16 years of age must be supervised by a licensed driver and must wear a helmet and eye protection. In addition to direct supervision, eye protection, over-the-ankle boots, and a safety helmet, those under 16 who want to operate the off-highway vehicle on a public land must also pass a safety course (Fla. Stat. §261.20(3)).
The operator of an off-highway vehicle may not carry a passenger unless a vehicle is specifically designed by the manufacturer to carry an operator and a single passenger (i.e. two-rider ATV).
Anyone who violates the above-mentioned laws commits a noncriminal infraction and is subject to a fine of not less than $100. In addition, he or she might be prohibited from operating an off-highway vehicle on public lands. The fine for a second or subsequent violation or for a violation with intent to defraud is not less than $500. (Fla. Stat. 261.20(6)).
A low-speed vehicle may be operated on the streets only if the posted speed limit is 35 mph or less. (Fla. Stat. §316.2122). However, the rider of a low-speed vehicle may cross a road or street at an intersection where that road or street has a higher speed limit. In addition to being equipped with headlamps, stop lamps, turn signal lamps, tail lamps, reflex reflectors, parking brakes, rearview mirrors, windshields, seat belts, and vehicle identification numbers, a low-speed vehicle must be registered and insured and its operator must always have in its possession a valid driver's license.
