I'd take this as evidence they monitor every connection that isn't over http ... which happens to include VPNs and Tor. Otherwise, they would have just said "We do not monitor your internet connection except to gather aggregate statistics for billing purposes".
They damn well better not be.

They are clearly logging some things. I'm mostly amused people want to downvote my comment and pretend it isn't happening.

"The New Jersey Department of Transportation (NJDOT) maintains traffic cameras on many interstates and other New Jersey State highway systems. The cameras are mounted on poles and record traffic conditions, traffic delays, incidents and weather conditions. They are monitored around the clock at NJDOT's Statewide Traffic Management Center.
In the Department's video camera system, video is recorded and retained at NJDOT for seven (7) days. "
