Real estate Q&A: Can a condo community post speed limit signs?

Source: Boston Herald — 

Q: I live in a small condominium community. Several residents are complaining about speeding vehicles and delivery trucks. We are thinking of posting 15 mph speed limit signs, although the streets outside our community allow faster travel. Can we do this, and what else can we do to slow drivers down and prevent someone from getting hurt? —Margaret

A: Not only can you post speed limit signs, but you also should.

Your association, acting under the authority of its governing documents, may create community guidelines and take measures to enforce those rules.

Like any other association rule, a community traffic rule is enforced in similar ways, such as issuing violations and even small fines.
