The New York City Department of Transportation has unveiled new signage meant to deter truck crashes on city parkways.

The DOT and NYPD are teaming up to introduce the new, bright red signage on parkways citywide to replace signs that some truck drivers say are too small. The markings will remind drivers that parkways are for passenger vehicles only.

Many of the signs have already been installed on the FDR Drive, where the city is testing the plan before expanding it to other roadways like the Hutchinson River Parkway.

The DOT says oversized vehicles struck bridges 52 times last year in New York City, with several of those collisions occurring at Waters Place and Westchester Avenue. From 2010 to 2016, the DOT says there have been more than 90 truck strikes at the Hutchinson River Parkway overpass.

The DOT announced last year a new system designed to keep taller commercial vehicles off of low-clearance parkways. The new detection system uses infrared beams to identify oversized vehicles using a parkway and then alert the driving using electronic messaging signage.
