Unless otherwise posted, what is the statutory speed limit in a thickly settled or business district in Massachusetts?
The answer
Answer: A. Under Massachusetts law, the statutory speed limit in a thickly settled or business district is 30 miles per hour unless signs show a lower 25 mph limit. Speed limits are maximums for good conditions, so your speed is not reasonable and proper if you drive over the limit for the area, and you may need to go slower in rain, fog, or heavy traffic.
