These are crowdsourced reports of selected vehicle and fleet
categories reported blocking bike lanes from May through September
2026, mostly in greater Boston. They are a record of what was
reported, not a rate of how often any vehicle type blocks a lane.
Categories were assigned with automated tagging and manual review.
Photos get smaller higher in each stack so every report fits. Column
heights are compressed, not proportional to report counts. The
number beside each group is the exact count.
Reports come from
Loud Bicycle's Bike Bureau. Their FAQ explains
how reports are collected.
