Crash Type   Motorist drove through intersection  --   9.6%

In this crash type, the motorist enters an intersection and fails to stop at a red light or stop sign, hitting a bicyclist who is traveling through the intersection. Twenty-four percent of bicyclists are riding the wrong way against traffic (20 percent on the sidewalk or road in the first half of the intersection). Almost one third of the bicyclists hit are traveling with traffic in the far side or second half of the intersection.

In crashes where motorists are failing to yield at Stop sign or signal controlled intersections, potential countermeasures should focus on getting drivers to stop and yield. However, as many of these crashes also involve bicyclists who are riding the wrong way against traffic, there may also be value in tackling wrong-way riding.

Countermeasures
-- Lengthen Yellow Time
-- Increase visibility of the sign or signal
-- Slow vehicles down on intersection approach
-- Enforce Red Light Running
-- Decrease wrong-way riding
