If you drive up to the White Mountains for hiking or skiing there are a couple of notorious speed traps that you should be aware of.
The tiny town of Twin Mountain, New Hampshire is located at the junction of Route 3 and Route 302. Do yourself a favor and don’t drive over the limit anywhere near this town. The local police are very vigilant at pulling over speeders at the traffic light where Route 3 and 302 meet, particularly if you are driving north from Crawford Notch on 302. They also lie in wait in the parking lots that line Rt 3 in the middle of town and catch speeders driving east or west on Route 3.
If you are driving east on Route 2 past the Northern Presidentials (Madison, Adams, and Jefferson), you will drive down a very steep hill that has a gravel emergency truck ramp at the bottom of it. There’s a speed trap here, right where the speed limit drops to 30 mph.
If you are driving south on Interstate 93, there is a speed trap just south of Franconia Notch, after the road splits back into two lanes. After driving the 45 mph limit through the Notch, drivers like to speed up to 65/70 mph even though the speed limit only goes up to 55 mph for the next mile. I see people get pulled over here by the New Hampshire State Police all of the time. When you exit Franconia Notch, don’t speed up until you see the speed limit sign that says 65 mph.
Concord City Line, Route 93
If you are driving south on Interstate 93, there is a well-established speed trap just north on the city of Concord, about a mile north of the bus station. It’s right where the speed limit drops from 65 mph to 55 mph. There is usually a State Police car parked at the turnaround picking speeders off in the late afternoon or evenings as they drive home from the Whites.
Massachusetts Border to Lincoln, NH
If you are driving northbound on Interstate 93 from Massachusetts, you should consider anything between the MA/NH border and Lincoln, New Hampshire (Exit 32) to be a giant speed trap, especially if you have Massachusetts license plates. Don’t think that you can get away with speeding at off hours, either. I once got a very expensive ticket driving in 93 North before sunrise, and since then, I stick to the 65 mph limit with cruise control whenever I head north to the mountains.
