Coordinated Campaign Aims to Crack Down on Speeders in Mass., N.H., and Maine

A regional task force organized by the National Highway Traffic Safety Administration (NHTSA) is working with local law enforcement to stop speeding in its tracks. Officials from the NHTSA, law enforcement representatives, and highway safety officials from Massachusetts, New Hampshire, Maine, Vermont, and Connecticut announced the initiative during a joint news conference on Thursday in Seabrook, New Hampshire. The police aren’t looking to hassle drivers, but Kinsman said it doesn’t take long to find people speeding and driving aggressively at excessive speeds.
