Barring a springtime snow storm, sneckdown season is over. In this Streetfilm, Clarence Eckerson Jr. shows how DOT is following nature’s lead with inexpensive and effective treatments that slow driver turns — and remain in place year-round.

Last year DOT began installing ”slow turn boxes” — curb extensions made from flex-posts and paint — at intersections where turning motorists injure a lot of people walking. DNAinfo reported that a pilot program will bring the boxes to 100 intersections citywide.

Watch how the turn boxes, and other low-cost neckdowns, are improving visibility and getting motorists to slow down.
