Lane Splitting Is Not Authorized, But Two Riders May Share A Lane

Ohio law approaches motorcycle lane position from two directions, and neither of them creates a splitting or filtering privilege. R.C. 4511.55 is the section that governs how bicycles, electric bicycles and motorcycles occupy a roadway, and its only division touching motorcycles is (B), which is permissive rather than prohibitive: riders may go not more than two abreast in a single lane, except on paths or parts of roadways set aside for the exclusive use of bicycles, electric bicycles, or motorcycles. Two Ohio riders may therefore legally share one lane, and Ohio contemplates motorcycle-only lanes even though it has not built them. What R.C. 4511.55 never does is authorise a rider to occupy the space between two lanes.

The prohibition itself comes from R.C. 4511.33, the marked-lanes section. Division (A)(1) reads: "A vehicle or trackless trolley shall be driven, as nearly as is practicable, entirely within a single lane or line of traffic and shall not be moved from such lane or line until the driver has first ascertained that such movement can be made with safety." A motorcycle is a vehicle for this purpose, and R.C. 4511.33(A) applies both where a roadway is divided into two or more clearly marked lanes and, within municipal corporations, wherever traffic is lawfully moving in two or more substantially continuous lines in the same direction. That second clause matters in Ohio cities, because it reaches unmarked but congested streets in Columbus, Cleveland and Cincinnati where filtering would otherwise be tempting.

The absence of a splitting rule is demonstrable rather than assumed. A full-text phrase search of the Ohio Revised Code on the Legislative Service Commission's own site returns no records for "lane splitting", no records for "lane filtering", no records for "between lanes" and no records for "rows of vehicles". The phrase "two abreast" appears in exactly one section, R.C. 4511.55. Ohio has neither authorised the practice nor written a bespoke ban on it, so a rider is left with the ordinary lane rule that applies to every car on the road.

Passing on the right is the manoeuvre riders most often confuse with filtering, and Ohio confines it tightly. R.C. 4511.28(A) permits overtaking and passing on the right only when the overtaken vehicle is making or about to make a left turn, or upon a roadway with unobstructed pavement of sufficient width for two or more lines of vehicles moving lawfully in the direction being travelled. Division (B) adds that the movement shall not be made by driving off the roadway. Slipping up the right-hand edge of a single occupied lane, or onto the berm, therefore breaks R.C. 4511.28 as well as R.C. 4511.33.

R.C. 4511.55 in its present form dates from March 8, 2019, when House Bill 250 and House Bill 95 of the 132nd General Assembly both amended it and the Legislative Service Commission published the result as a composite under R.C. 1.52(B). That round of amendment added electric bicycles to the section; it did not add lane splitting. Riders wanting the practice legalised in Ohio would need a new section, not a reading of the existing one.

C. C. C. 28(A)(2)(a)(v) with no jail term available. C. 24(A)(4) and a fine of up to $250; with two or more such prior offences inside a year it becomes a misdemeanor of the third degree, up to 60 days and a fine of up to $500. C. 991 applies. Enforcement is by the State Highway Patrol, municipal police and county sheriffs. C. 036(C)(16), which assigns two points to all moving violations other than the ones the section prices individually. C. C. 037(B), so lane-position convictions are not trivial for a rider who already carries speeding points. Beyond the citation, splitting exposes the rider in any civil claim, because riding outside the lane is a straightforward breach of a safety statute.
