Legal right turns on red are practically a given at intersections from rural Oklahoma to urban Boston. But it wasn’t always so.
It wasn’t until the 1970s that allowing drivers to turn right during the red signal phase became common across the country, says Bill Schultheiss, a civil engineer at Toole Design Group who specializes in bike facilities.
Precipitated by the OPEC oil embargo, the Energy Policy and Conservation Act of 1975 required states to allow rights on red to receive certain federal funds. Decades later, every state in the U.S. allows rights on red everywhere — other than New York City — except when prohibited by signage.
Letting drivers turn on red can save gas, but there is a trade-off. Though recent studies are lacking, the body of research shows that allowing rights on red compromises safety for people who walk and bike.
