Go to Google and search “truck routes city.”
You’ll find hundreds of links to cities with delineated truck routes, many of which explain the need for these routes in word similar to those used in Stockton, California:
Trucks and commercial vehicles are essential to the region, providing goods and services to the residents every day. The City’s diverse mixture of land uses, dense urban environment and vast transportation infrastructure require a distinct set of rules and regulations to govern the operation of trucks and commercial vehicles on city streets. In order for this system to function efficiently, it is important that drivers observe these rules and regulations. The City of Stockton Truck Route Map is available to help truck and commercial vehicle operators.
In New Albany, Mayor Gahan’s explanation of truck routes relies on a convenient pictogram.
