About this app

The Mass511 app is the Massachusetts Department of Transportation's official traffic and traveler information app. The Mass511 app, new and improved in 2022, provides up-to-date traffic information for interstates, U.S. routes and state highways across Massachusetts.

FEATURES:
• Hands-free, eyes-free audio notifications of traffic events while you drive
• A zoom-enabled map with tappable traffic event icons and surrounding camera views
• Near real-time updates on traffic incidents, construction, weather and road closures
• Manage My Mass511 personalized accounts including saved routes, areas, and camera views and email and text alerts
• View current traffic speeds
• View traffic cameras throughout the state. Sign up for a My Mass511 account to save cameras for easy access.
• Access to additional traveler information resources

NOTE: Continued use of GPS running in the background can decrease device battery life.

The primary responsibility of every driver is the safe operation of their vehicle. While traveling, mobile communication devices should be used only when the motor vehicle is at a complete stop, off the traveled portion of the roadway. Do not text and drive (it's against the law) or use this app while driving.

Ratings and reviews

It does the job, but it's hard to see where the traffic is. When the app opens, sometimes it's difficult to figure out exactly what part of the map is being displayed. The old SigAlert app made incidents and traffic conditions much easier to see, with an interactive feature that allowed a user to select an incident and learn what lane it was in, and exactly where it was. Unfortunately, SigAlert isn't available for the later version of Android on my new phone.

App fails to give road weather conditions, a crucial piece of information for travel and travel planning. Road information available is scant, much of the info is more easily available embedded in other apps that have more usefulness otherwise.

Cameras never work. Great idea but if they don't work, why bother. Could be a fantastic app if only...
