Can you use a four wheel off road vehicle on American Beach in Florida?

Yes. You can drive south from American Beach on Amelia Island. Don't stop in front of the resorts they get real upset about that. The speed limit is 15 mph. Drive past the resorts to the Nassau Sound inlet at the southern end of the Island. Watch out for drop offs and the high tide. The currents near the inlet are very dangerous so no swimming. However, fishing is great. Check with the Nassau County sherriffs office to get the lastest rules.
