I understand that the city has designated truck routes for commercial vehicles. I'm just curious . I've lived here for 40 years and have never noticed it enforced. We have several vehicles a week cruise through our neighborhood, past a no truck sign. It's been reported several times over the years. This isn't the only place I've noticed 78th Av, and 82nd Av are both no truck routes and commercial trucks use them to cut through to US 19 instead of using the designated truck routes. Are these routes enforced??
