Digest of Ohio Bicycle Traffic Laws
By the Ohio Bicycle Federation
Revised:  2 June 2002

Title 45 of the Ohio Revised Code contains the laws that govern operation of vehicles on Ohio roads.  The laws describe only what a driver is required to do or prohibited from doing.  But laws do not tell people how to drive.  That is the function of a driver’s manual. 

There are a few books that make excellent driver’s manuals for cyclists:  Street Smarts by John Allen is a concise booklet that summarizes what all cyclists should know.  The booklet was issued by the Ohio Department of Public Safety as Ohio Bicycling Street Smarts.  It was also used for the Pennsylvania Bicycle Driver's ManualStreet Smarts is available from Rubel Bikemaps, http://www.bikemaps.com/bss.htm

The books Effective Cycling and Bicycle Transportation by John Forester give a more complete treatment but are difficult reading for beginners.  Effective Cycling is available at any good bookstore.  Every active cyclist should have a well-worn copy of it on his bookshelf.

The people who follow the techniques in these books will reduce their accident rate by 80% compared to average untrained cyclists.  Cycling in this way is also more effective and more enjoyable and it allows riding confidently in many more places than would otherwise be possible.

Below are annotated excerpts from Ohio traffic law of concern to cyclists. If you want to look-up Ohio traffic law for yourself, you can access the entire Ohio Revised Code online, http://onlinedocs.andersonpublishing.com/revisedcode/.  The traffic laws are in Title 45. You can also go directly to Chapter 4511 (the rules of the road) and  Chapter 4513 (equipment rules).

§ 4501.01 Definitions.
As used in this chapter and Chapters 4503., 4505., 4507., 4509., 4511.,4513., 4515., and 4517. of the Revised Code, and in the penal laws, except as otherwise provided:

(A) "Vehicles" means everything on wheels or runners, including motorized bicycles, but does not mean vehicles that are operated exclusively on rails or tracks or from overhead electric trolley wires and vehicles that belong to any police department, municipal fire department, or volunteer fire department, or that are used by such a department in the discharge of its functions used in this chapter and in Chapter 4513. of the Revised Code:

Comment:  A bicycle is defined as a vehicle and thus is governed by a uniform set of rules common to all vehicles and a small set of specific rules for bicycles.  (There are other specific rules for other vehicle types, such as trucks or busses.)  The annotated list below summarizes the most important parts of the traffic rules and equipment rules that govern bicycle driving.  People who try to make up their own rules have an accident rate five times higher than experienced cyclists who follow the rules of the road.

§ 4511.52 Bicycles.
Sections 4511.01 to 4511.78, inclusive, 4511.99, and 4513.01 to 4513.37, inclusive, of the Revised Code which are applicable to bicycles apply whenever a bicycle is operated upon any highway or upon any path set aside for the exclusive use of bicycles.

Comment:  Bicycle drivers are subject to almost all of the driving laws as are drivers of other vehicles.  These driving laws allow safe, fast and efficient travel.  Riding on sidewalks or multi-use bike paths is moderately safe only if done very carefully and at extremely slow speeds.  Riding on paths is popular for recreation but provides limited utility for transportation.  Thus path riding is not covered in this digest.

§ 4511.25 Lanes of travel upon roadways.
(A) Upon all roadways of sufficient width, a vehicle or trackless trolley shall be driven upon the right half of the roadway …
(B) Upon all roadways any vehicle or trackless trolley proceeding at less than the normal speed of traffic at the time and place and under the conditions then existing shall be driven in the right-hand lane then available for traffic, or as close as practicable to the right-hand curb or edge of the roadway, except when overtaking and passing another vehicle or trackless trolley proceeding in the same direction or when preparing for a left turn.

Comment:  Section 4511.25(A) is a general rule that applies to all vehicles, including bicycles. Some people think it is safer to ride on the left to “see traffic coming”.  Pedestrians walk facing traffic so they can sidestep off the road if necessary.  But you cannot sidestep a bike.   Riding on the left is both illegal and dangerous.  Accident statistics show that wrong way riding is about 3½ times as dangerous as riding on the right.

Section 4511.25(B) simply means that slower vehicles should not unnecessarily delay faster traffic.  (See also § 4511.55 below.)

§ 4511.55 Riding bicycles; motorcycles abreast.
(A) Every person operating a bicycle upon a roadway shall ride as near to the right side of the roadway as practicable obeying all traffic rules applicable to vehicles and exercising due care when passing a standing vehicle or one proceeding in the same direction.

(B) Persons riding bicycles or motorcycles upon a roadway shall ride not more than two abreast in a single lane, except on paths or parts of roadways set aside for the exclusive use of bicycles or motorcycles.

Comment:  Section 4511.55(A) is the most misunderstood law for bicycle operation.  Some people think this requires riding as close as possible to the edge of the road.  However, there are conditions where it is much safer to ride further out in the lane.  It is not practicable (practice-able) to ride far to the right when passing or turning left; or when avoiding objects, parked cars, moving vehicles, pedestrians, animals, surface or other hazards; or when riding in a vehicle lane too narrow for a bicycle and another vehicle to pass safely side by side within the lane.

Many motorists are reluctant to cross a lane line when passing a bicycle.  A cyclist who “hugs the curb” unintentionally invites motorists to pass with unsafe clearance.  Riding near the middle of a narrow lane “sends the message” that passing traffic must use the next lane.

The real purpose of this law is to prevent unnecessary delay to faster traffic.  Since the law cannot require unsafe operation, the phrase as close as practicable is highly flexible, varying widely according to conditions.  Positions well away from the edge of the road can be in compliance.

Section 4511.55(B) allows riding two abreast.  However, cyclists are still required to avoid unnecessary delay to other traffic.  Please be courteous and “single up” when other drivers wish to pass as long as such passing is safe and reasonable.  There is no violation if any of the following apply:  (1) If there is no traffic being delayed; (2) If the cyclists are traveling as fast as other traffic; (3) If traffic can reasonably pass by using another lane; (4) If the lane is too narrow or it is otherwise unsafe for passing.

§ 4511.27 Rules governing overtaking and passing of vehicles.
The following rules govern the overtaking and passing of vehicles or trackless trolleys proceeding in the same direction:

(A) The operator of a vehicle or trackless trolley overtaking another vehicle or trackless trolley proceeding in the same direction shall … pass to the left thereof at a safe distance, and shall not again drive to the right side of the roadway until safely clear of the overtaken vehicle or trackless trolley.

(B) Except when overtaking and passing on the right is permitted, the operator of an overtaken vehicle shall give way to the right in favor of the overtaking vehicle at the latter's audible signal, and he shall not increase the speed of his vehicle until completely passed by the overtaking vehicle.

Comment:  Since cyclists usually ride near the right side of the road, beginners are tempted to pass slow or stopped traffic on the right.  Passing on the right is usually dangerous and, in many cases, illegal.

§ 4511.36 Rules for turns at intersections.
The driver of a vehicle intending to turn at an intersection shall be governed by the following rules:

(A) Approach for a right turn and a right turn shall be made as close as practicable to the right-hand curb or edge of the roadway.

(B) At any intersection where traffic is permitted to move in both directions on each roadway entering the intersection, an approach for a left turn shall be made in that portion of the right half of the roadway nearest the center line thereof and by passing to the right of such center line where it enters the intersection and after entering the intersection the left turn shall be made so as to leave the intersection to the right of the center line of the roadway being entered.  Whenever practicable the left turn shall be made in that portion of the intersection to the left of the center of the intersection.

Comment:  The rules for turns are exactly the same for bicycles as for other vehicles – merge to the appropriate position (right for right turns, left for left turns), yield to any traffic that has the right of way, and turn.

Getting into position for a left turn involves merging across lanes of traffic.  If traffic is heavy, you may need to start doing this early to take advantage of gaps in traffic.  Otherwise, there may not be a gap when you need it.  Beginners, who have not yet developed the skill to merge in traffic, may make pedestrian-style turns instead.

§ 4511.39 Turn and stop signals.
No person shall turn a vehicle or trackless trolley or move right or left upon a highway unless and until such person has exercised due care to ascertain that the movement can be made with reasonable safety nor without giving an appropriate signal in the manner hereinafter provided.

When required, a signal of intention to turn or move right or left shall be given continuously during not less than the last one hundred feet traveled by the vehicle or trackless trolley before turning.

Comment:  Never turn or change lanes without first yielding to any traffic that has the right of way, and then give a signal if possible.  Skip the signal if your hand is needed for control or brakes,.

§ 4511.40 Hand and arm signals.
(A) Except as provided in division (B) of this section, all signals required by sections 4511.01 to 4511.78 of the Revised Code, when given by hand and arm, shall be given from the left side of the vehicle in the following manner, and such signals shall indicate as follows:

(1) Left turn, hand and arm extended horizontally;

(2) Right turn, hand and arm extended upward;

(3) Stop or decrease speed, hand and arm extended downward.

(B) As an alternative to division (A)(2) of this section, a person operating a bicycle may give a right turn signal by extending the right hand and arm horizontally and to the right side of the bicycle.

Comment:  The right-arm turn signal described in (B) above is more easily understood.

§ 4511.54 Prohibition against attaching bicycles and sleds to vehicles.
No person riding upon any bicycle, coaster, roller skates, sled, or toy vehicle shall attach the same or himself to any streetcar, trackless trolley, or vehicle upon a roadway.

§ 4511.56 Signal devices on bicycle.
(A) Every bicycle when in use at the times specified in section 4513.03 of the Revised Code, shall be equipped with the following:

(1) A lamp on the front that shall emit a white light visible from a distance of at least five hundred feet to the front;

(2) A red reflector on the rear of a type approved by the director of public safety that shall be visible from all distances from one hundred feet to six hundred feet to the rear when directly in front of lawful lower beams of head lamps on a motor vehicle;

(3) A lamp emitting a red light visible from a distance of five hundred feet to the rear shall be used in addition to the red reflector;

Comment:  An unseen cyclist is in great danger.  About 30 percent of serious cycling causalities occur at night although only about four percent of cycling is done then.  The reflectors that come with new bikes are grossly inadequate for nighttime visibility.  Always use both a headlight and taillight when you ride in the dark.

§ 4511.711 Driving upon sidewalk area.
No person shall drive any vehicle, other than a bicycle, upon a sidewalk or sidewalk area except upon a permanent or duly authorized temporary driveway.

Comment:  Although this section allows riding on sidewalks, don’t do it.  Accident studies show that even low-speed sidewalk riding has about double the accident rate as riding on the road.  The danger increases with speed.  If you ride on the sidewalk, every intersection and even every driveway is a potential collision site.  Motorists crossing your path do not look for conflicting traffic on the sidewalk, especially if you are coming from the “wrong way”.
