User are reporting turn not allowed errors along a section of Boylston Street that seem to all be originating from the two intersections below:
When heading east on Boyston Street the right turn onto Warren Street is prohibited during the morning rush hour from 7-9 AM.
Continuing east on Boylston Street the next right onto Kenndard Road is also time restricted.
If these two turns were prohibited in Waze, morning rush hour traffic from the east would probably be routed one turn earlier onto Lee street or onto Cypress Street a few streets farther down Boylston Street depending on the final destination.
These roads are locked at level 5 so someone with more experience than myself can decide if restricting these two right turns is a good idea or not.
