Frequently Asked Questions About Massachusetts Trucking Regulations
What roads are prohibited for trucks in Boston?
Storrow Drive and Memorial Drive along the Charles River are the most famously truck-prohibited roads in Boston. Numerous bridge strikes occur annually by drivers ignoring warning signs. Commercial GPS must be set to truck mode to avoid these and other restricted roads in the Boston area.
What are the Massachusetts Turnpike tolls for trucks?
The Massachusetts Turnpike (I-90) uses all-electronic tolling with no cash option. Truck tolls vary by distance: approximately $4-20+ depending on entry and exit points. E-ZPass users pay lower rates. Tolls are charged via transponder or license plate billing.
Can hazmat loads use Boston tunnels?
No, all hazmat placarded vehicles are prohibited from using the Sumner, Callahan, and Ted Williams tunnels in Boston. Hazmat loads must use surface routes or I-93/I-95 bypass options, significantly impacting routing through the metro area.
How does winter weather affect Massachusetts trucking?
Massachusetts experiences severe nor'easter storms that can dump 12-24+ inches of snow and shut down highways. Governor-ordered travel bans prohibit commercial vehicle operation during the worst storms. Drivers should monitor forecasts and carry winter survival gear from November through March.
Is truck parking available in Boston?
Truck parking in the Boston metropolitan area is extremely limited and expensive. Turnpike service plazas offer some parking but fill quickly. Drivers delivering to Boston should plan parking well in advance and consider staging at facilities along I-495 or I-290 before making final delivery runs.
