This new law officially goes into effect on March 21st of this year. A measure of this nature is not only important to protect riders, but it serves as a very prominent message to build awareness for drivers, and makes local ordinances already on the books in Cleveland, Columbus, Bay Village, Cincinnati, and other Ohio municipalities uniform with state law. Many motorists are simply unaware or unsure of the space requirements people on bikes need to operate safely, and this law will help them understand what is expected of them on the roadway.
HB154 amends the Ohio Revised Code: “To amend sections 4511.132 and 4511.27 of the Revised Code to provide that when a motor vehicle passes a bicycle the safe passing distance to the left is three feet or greater, and to alter the protocol for proceeding into an intersection that has malfunctioning traffic lights”
In addition, In addition, the new law allows for special consideration at intersections that utilize detection equipment that often does not work for smaller, lighter vehicles such as bicycles. The law will: “Permit any Ohio vehicle to proceed through an intersection after stopping and yielding right-of-way, even when not detected by the device meant to move the signal from red to green.”
