In Ohio, are you allowed to turn left at a red signal?

In Ohio, you can turn left on a red light when you are turning from a one-way street onto another one-way street, unless signs prohibit it. You must still come to a complete stop and yield to all pedestrians and traffic before you turn. Note: The laws on this are different in some other states. A few states (e.g., Idaho) also allow you to turn left on red from a two-way street onto a one-way street. Still other states (e.g., South Dakota) prohibit left turns on red altogether. When traveling out of state, always check the local traffic laws. [Left Turn on Red, Correct Methods of Making Left Turns, 6 – Traffic Laws, Digest of Ohio Motor Vehicle Laws]
