Ayres Knowledge Center Using Bike Boxes to Increase Visibility and Safety | Page 9

An R10-6A (Stop Here on Red) sign can be installed near
the stop bar to define the location where motorized
vehicles should stop, which is behind the bike box at
the stop bar. Bike box message signs, which vary in their
design, are sometimes installed on signposts or on the
traffic signal poles at the intersection when bike boxes are
first applied to reiterate the message that bicyclists have
the option to move into this marked area when the traffic
signal is holding motorists at a red signal.
When issues exist where right-turning vehicles often
conflict with bicyclists, it is common for an R10-11 (No Turn
on Red) sign to be installed to restrict right turns on red,
allowing bicyclists to safely enter the bike box area without
fear of right-turning vehicles causing right-hook crashes
with bicyclists. Using bike boxes to put bicyclists in front
of traffic, along with enforcement of the no-turn-on-red
regulation, can reduce the chance of right-hook crashes.
