That’s when motorcyclists race past those crawling along on four wheels or more, riding in between travel lanes when traffic snarls. Regardless if it’s done near the express lanes or the regular lanes, lane-splitting is illegal in Florida, as it is in most other states. The fines vary. Those caught lane-splitting in Broward will be fined $165. In Miami Dade, it’ll cost you $179. In Palm Beach County, $166.
