Lane splitting is expressly illegal in Florida

Section 316.209 of the Florida Statutes is titled Operating motorcycles on roadways laned for traffic, and it does three separate things that riders often collapse into one. Subsection (1) grants the entitlement: all motorcycles are entitled to full use of a lane, and no motor vehicle may be driven in such a manner as to deprive any motorcycle of the full use of a lane. That is the rider's protection against being crowded or squeezed by a car sharing the lane. It comes with a condition, though, in the second sentence of the same subsection: the entitlement does not apply to motorcycles operated two abreast in a single lane. A rider who chooses to pair up with another rider in one lane gives up the statutory claim to that full lane.

Subsection (2) closes off in-lane filtering. The operator of a motorcycle may not overtake and pass in the same lane occupied by the vehicle being overtaken. That is the manoeuvre of slipping up the inside of a car within its own lane, and Florida prohibits it independently of whether the rider crosses a lane line. Subsection (3) then reaches the manoeuvre most people mean by lane splitting: no person shall operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles. The second half of that phrase matters. By reaching adjacent lines or rows of vehicles, not merely marked lanes, subsection (3) covers a queue stopped at a signal on an unmarked approach, two informal columns of traffic backed up at a toll plaza, and rows in a parking area, none of which are lanes in the striped sense.

What the section does not contain is as important as what it does. There is no stopped-traffic exception, so filtering to the front of a red light is prohibited in Florida exactly as splitting a moving freeway is. There is no speed-differential allowance of the kind that appears in states which have legalised the practice. There is no HOV or congestion carve-out, no daylight or weather condition, and no authority anywhere in section 316.209 for a county or municipality to permit splitting on roads under its jurisdiction. Chapter 316 contains no counterpart section authorising lane sharing, so the prohibition in subsection (3) is the whole of Florida law on the subject and it applies uniformly to every road in the state, including private ways over which a local government has assumed traffic jurisdiction under section 316.006.

One form of lane sharing does remain lawful. Subsection (4) provides that motorcycles shall not be operated more than two abreast in a single lane, which by negative implication permits exactly two riders to share a lane side by side. That is the standard Florida group-riding formation, and it is the same conduct that switches off the full-lane entitlement in subsection (1). Three abreast is a violation. The paired riders are still bound by subsections (2) and (3), so a pair may not filter forward through stopped traffic together.

Subsection (5) supplies the only exemption in the section: subsections (2) and (3) do not apply to police officers or firefighters in the performance of their official duties. Note the precision of that drafting. The exemption reaches only the in-lane passing rule and the between-lanes rule. It does not lift subsection (4), so even an official escort formation may not run more than two abreast in a lane, and it does not extend to emergency medical technicians, tow operators or civilian escort riders. An off-duty officer riding personally is outside it as well, because the exemption is tied to performance of official duties rather than to occupation.

Riders sometimes assume that section 316.2085, which governs riding on motorcycles and mopeds, provides a route around this. It does not. That section requires a rider to sit astride the permanent and regular seat with both wheels on the ground at all times, facing forward with one leg on each side, and forbids carrying any package that prevents keeping both hands on the handlebars. It says nothing about lane position. Section 316.209 is the only lane-position provision for motorcycles in Florida, and it has read this way since the traffic code was recodified, with its most recent substantive amendment made by chapter 2003-92, Laws of Florida. The section derives from former section 316.109.

Subsection (6) of Fla. 209 makes a violation of any part of the section a noncriminal traffic infraction, punishable as a moving violation as provided in chapter 318. 18(3)(a) the penalty for a moving violation not requiring a mandatory appearance is $60, before the court costs and surcharges a clerk adds. 27(3)(d) assigns 3 points to the conviction under the catch-all entry for all other moving violations. 27(3)(a) through (c): 12 points within a 12 month period brings a suspension of up to 30 days, 18 points within 18 months brings up to 3 months, and 24 points within 36 months brings up to 1 year.

Where the split results in a crash, the same schedule assigns 4 points for any moving violation covered in that paragraph, excluding unlawful speed and unlawful use of a wireless communications device, which results in a crash. Any state, county or municipal law enforcement officer with traffic jurisdiction may write the citation, and the Florida Highway Patrol enforces the section on the State Highway System. Beyond the citation, a rider cited under subsection (3) after a collision faces the practical consequence that the violation is evidence of negligence in the civil claim, because the manoeuvre is unlawful rather than merely disfavoured.
