Earlier this month, the city announced a pilot program to add side guards, which prevent people from being dragged under the rear wheels of large vehicles, to 240 trucks in the city fleet. It’s a start, but there are thousands more trucks on NYC streets that need this life-saving equipment.

A new report from the U.S. Department of Transportation’s Volpe Center lays out an action plan specifically for New York City [PDF], describing a path to expand side guards across the city’s fleet of trucks.
The Volpe Center recommends better data collection by NYPD and the state DMV to study the safety impacts of the city’s pilot program, but the effect of side guards is already clear. After the United Kingdom began requiring them in 1986, the fatality rate for pedestrians hit by the side of a truck fell by 20 percent. For bicyclists, the fatality rate decreased 61 percent.
Trucks make up just 3.6 percent of vehicles on the road in New York City, but they account for 12.3 percent of pedestrian fatalities and 32 percent of bicyclist fatalities, according to city data cited by the Volpe Center. Pedestrians are three times more likely to die after being hit by a truck or bus than by a passenger car. Truck side impacts are particularly deadly for bicyclists. More than 50 percent of cyclists struck by the side of a truck die, mostly after falling beneath the vehicle’s wheels.
The Volpe Center identified 4,734 medium- and heavy-duty trucks as candidates for side guards. These include dump trucks, salt spreaders, trailers, fuel tankers, and other types of trucks operated primarily by the Department of Sanitation, DOT, Parks, the Department of Education, NYPD, the Department of Environmental Protection, and the Department of Corrections.
Volpe recommends installing solid panel-style side guards, rather than rail-style guards, and suggests stainless steel or plastic composites rather than aluminum, which is vulnerable to salt corrosion. Street sweepers, fire engines, car carriers, and special-purpose vehicles, such as movable highway barrier “zipper” trucks, would be exempt because side guards are either unnecessary or incompatible.
Of the 4,734 vehicles that could use side guards, half are garbage trucks, mostly operated by the Department of Sanitation. While garbage trucks have about 30 different equipment configurations that could complicate side guard retrofits (Volpe says that the cost of “fitting a single-unit truck with side guards, based on discussions with the identified vendors, ranges from $600 to $2,500″), they are replaced more frequently than other city vehicles, meaning that side guards could become standard equipment relatively quickly.
