Here’s a quote from a new article on bike boxes on the North Carolina Coalition for Bicycle Driving site:
Bike boxes suffer from two fundamental design flaws:
1. They direct bicyclists to pass on the right side of traffic that may turn right at any moment.
2. They direct bicyclists to turn left and cross in front of other traffic with no signal-protected clearance interval at near zero sight distance.
A few local municipalities in NC have been considering bike boxes; I hope this article helps them understand the safety concerns associated with these non-standard designs.Tweet
