As the first of its kind in the nation, the Truck Side Guard ordinance championed by Mayor Walsh applies to motor vehicles weighing over 10,000 lbs. and semi-trailers with a total weight exceeding 26,000 lbs. The ordinance requires City agencies to contract only with vendors that have properly installed the following: side guards, convex mirrors, cross-over mirrors, and blind-spot awareness decals. These features are intended to reduce the risk of unprotected road users from falling under the sides of vehicles and getting caught under the rear wheels. The ordinance does not apply to several types of large vehicles, such as agricultural trailers, fire engines, and trucks used exclusively for snow removal.
Studies by the U.S. Dept. of Transportation have determined the cost of side-guards to be an average of $847. *They are typically installed as a bolt-on addition and can be fixed or hinged *In the City of Boston pilot, each truck was outfitted for $1,200.
