(b) Each such county superintendent of highways shall cause to be determined, for all bridges and elevated structures under his jurisdiction, the capacity in tons of two thousand pounds which the bridge or structure will safely carry. At bridges or structures of insufficient strength to carry safely the legal loads permissible by section three hundred eighty-five of this chapter, the county superintendent of highways shall cause signs to be erected to inform persons of the safe capacity.

(c) Each such county superintendent of highways shall cause signs to be erected to inform persons of the legal overhead clearance for all bridges, and elevated structures on highways under his jurisdiction. The legal clearance shall be one foot less than the measured clearance. The measured clearance shall be the minimum height to the bridge or structure measured vertically from the traveled portion of the roadway. On bridges or structures having fourteen feet or more of measured clearance, no such signs shall be required. d. The legislative body of any county with respect to county roads in such county, may by local law, ordinance, order, rule or regulation, provide for the removal and storage of vehicles parked or abandoned on highways during snowstorms, floods, fire or other public emergencies, or found unattended where they constitute an obstruction to traffic or any place where stopping, standing or parking is prohibited, and for the payment of reasonable charges for such removal and storage by the owner or operator of any such vehicle.

(e) The legislative body of any county with respect to county roads in such county, may by local law or ordinance prohibit vehicles engaged in retail sales of frozen desserts as that term is defined in subdivision thirty-seven of section three hundred seventy-five of this chapter directly to pedestrians from stopping for the purpose of such sales on any such road or on all such roads. Nothing herein shall be construed to prohibit the operator of such vehicle from stopping such vehicle off of such road, in a safe manner, for the sole purpose of delivering such retail product directly to the residence of a consumer or to the business address of a customer of such retailer.
