New bright red signs that reads “All Trucks Must Exit” have been installed along the FDR Drive in Manhattan to remind drivers that only passenger vehicles are allowed on parkways. The goal is to reduce the number of trucks that strike overpasses. New markings have also been painted onto the roadway to warn of low clearance. DOT Commissioner Polly Trottenberg, said signs will be at critical locations along the parkway at the Harlem River Drive, on 155th street, 116th street, and 106th street.
