Idaho special bicycle laws

Idaho law allows cyclists to treat a stop sign as a yield sign. See http://www3.state.id.us/cgi-bin/newidst?sctid=490070020.K
It also allows a bicyclist to treat a traffic signal as a stop sign.

I would support the traffic signal aspect of this law as a second-rank stopgap for the installation of signal actuators that detect bicycles and that are smart enough to adjust the signal timing to the speed capability of the vehicle.

Today’s electromagnetic loop detectors can detect bicycles if properly designed and installed, but many jurisdictions are still installing ones that cannot, or installing them incorrectly. (For example, even Portland, Oregon installs bicycle-sensitive detector loops only in the bike lane, and so a bicyclist preparing a vehicular left turn, or overtaking traffic on the left, will not be able to trip the signal). Bicycling advocates should promote best practices in application of loop detectors, the most common detector technology.

But detector technology is improving, with video. ultrasonic and infrared detectors becoming able, at least in theory, to distinguish a bicycle from a motor vehicle. Bicycling advocates should promote continued research, development and application of improved signal detection technologies through professional organizations and through the National Committee for Uniform Traffic Control Devices.

All this said, there will still be intersections where the technology is not up to date, or where the detector is malfunctioning, or where fixed-interval signals produce a long red even though there is no cross traffic. I think that it is reasonable for bicyclists to be permitted to proceed cautiously on the red under such conditions. This special permission could, however, get out of control — on the one hand, with the engineering profession abdicating its responsibility to provide signals that work, and on the other hand with bicyclists abusing the rule and crossing at times when other traffic has to yield to them.

As to the stop sign provision: the most important message of the stop sign is to yield to cross traffic. Usually, a yield sign would be sufficient. Almost nobody, bicyclist or motorist, comes to a complete stop for a stop sign unless there is cross traffic to which to yield, or a short sight distance that requires a stop. Stop signs are heavily overused in this country, but unfortunately, stop signs are the first thing the public thinks of in order to increase traffic safety. For my comments on how this contrasts with European practice, please see this other posting.

Also, bicyclists don’t have a car hood in front of them and are able to see the intersection before pulling out into it, so a stop is needed less often. And bicyclists can restart faster and get across a smaller gap without stopping and putting a foot down. So I offer warmer support to the Idaho stop sign provision.
