Allowing cyclists to proceed through a “stop” sign if “the coast is clear”—essentially, treating a “stop” as a “yield” sign—is called a “rolling stop” in traffic planning and legal parlance. It’s been nicknamed the “Idaho Stop” because the Gem State legalized it all the way back in 1982.
For more than three decades, that law was all but unknown in the rest of the United States. Since 2017, seven other states—my native New York not being one of them!—have enacted similar legislation.
One reason more states and locales* haven’t allowed the “Idaho Stop” is that many drivers believe that it would cause cyclists to act un safely, and some cyclists have expressed the same fear about motorists. So, perhaps, it’s not surprising that too many lawmakers share such misperceptions, which are the basis for their opposition.
A new study from the Oregon State University’s College of Engineering contradicts such fears and misperceptions, which are a basis of much hostility between motorists and cyclists, and aggressive behavior by the former towards the latter. Thus, according to David Hurwitz, an OSU Transportation Engineering professor and the study’s lead, any move to enact “rolling stop” laws must include efforts to educate both motorists and cyclists.
He and his team came to this conclusion after a remarkably simple experiment that included bicycle and motor vehicle simulators. Pairs of subjects simultaneously operated each simulator and each member of the pair interacted with an avatar of the other in a shared virtual world.
The results underscored a tenet from previous research: Drivers are more hostile, and behave more aggressively toward, cyclists when they think, with or without justification, that we’re breaking the law. That means people need to be educated about the benefits of the “Idaho Stop” not only in places that don’t allow it, but in places that already have it.
The OSU team’s study also underscores what every dedicated cyclist, especially in places like my hometown of New York, knows: The faster we get through an intersection, the less likely we are to be in a catastrophic crash. And, as the OSU study reveals, when drivers understand as much, they’re more likely to approach an intersection at a slower speed and let cyclists proceed ahead of them.
I think education has to include law enforcement officials, especially traffic cops—including one who stopped me for going through a “Stop” sign on Long Island. As I recall, it was near the end of the month and he had an itchy ticket-writing hand. I explained to the honorable constable that my proceeding ahead of a school bus—which made a right turn— was safer for everyone, including the pedestrians who crossed after the bus driver and I cleared the intersection. He didn’t write the ticket, but he admonished me to “remember the law” because “the next officer might not be sympathetic.”
*—A few cities and counties allow the “Idaho Stop” even though they’re located in states that don’t.
