The Mass511 app reports information for interstates, U.S. routes and MA highways in Massachusetts. It does not include information for county roads or city streets.

Reminder, the primary responsibility of every driver is the safe operation of your vehicle. Massachusetts law prohibits individuals from using a handheld electronic communication device to write, send or read a text message while driving a motor vehicle.
