The food truck phenomenon sweeping cities across the nation has begun to roll into the south suburbs, and while happy patrons are eager to feast on the food specialties it brings, some communities are rethinking how they might regulate them.

These mobile restaurants must abide by state and federal hygiene codes, just like their stationary counterparts, and in addition must have a local hawker’s or peddler’s license. Some towns, like Raynham, don’t allow them at all. Others, including Westwood and Scituate, are either adding new policies or rewriting the old ones to impose more stringent oversight.
