Study: Drivers Pay Attention to Painted Bike Lanes

By Charles Pekow — It helps to paint bike lanes. When motorists see the paint, they’ll give cyclists more room, says what purports to be the largest study of the issue.

Even when controlling for the width of the road, the drivers gave more room when they saw the paint.
