8 Highway Habits That Instantly Tell a Massachusetts Driver From a New Hampshire One
Could you tell a Massachusetts driver from a New Hampshire driver in under a minute?
These are the highway habits that instantly tell a Massachusetts driver from a New Hampshire one.
Note: This is general information, not legal advice. Traffic laws and enforcement practices are subject to change, so confirm current requirements with the Massachusetts Registry of Motor Vehicles or the New Hampshire Division of Motor Vehicles.
1. Massachusetts Left
Picture a Massachusetts driver approaching a green light at a busy intersection outside Worcester.
A driver facing oncoming traffic guns it and turns left the instant the light changes, ahead of the cars coming straight at them.
It’s not legal.
Massachusetts law gives the right of way to oncoming traffic during a left turn, the same rule New Hampshire follows on paper.
The maneuver is common enough around Boston that it has a nickname, the “Massachusetts left,” and locals treat the green light as a starting gun, not a formality.
Cross into New Hampshire and that same green light plays out differently.
Drivers there tend to wait out the oncoming lane before turning, the way the rulebook describes it.
2. Skipping the Blinker
A New Hampshire driver merging onto I-95 near Portsmouth will usually flick a blinker on well before the lane change happens.
Merging onto the Mass Pike outside Boston, you might not see one at all.
The habit got noticeable enough statewide that MassDOT put reminders on its own electronic highway signs in May 2014.
The boards flashed “Use Yah Blinkah,” and the phrase stuck.
Waltham police later borrowed the same line for a local enforcement push, ticketing drivers who merged without one.
A campaign like that doesn’t get built for a habit that isn’t real.
Massachusetts drivers still skip the step often enough to notice.
New Hampshire has run no comparable campaign.
State troopers there routinely cite the state’s turn-signal statute at traffic stops, evidence of a smaller gap between the rule and the habit.
3. Stopping for Cash at the Tolls
A New Hampshire driver rolling south on I-95 still hits a toll plaza, with a barrier arm and a choice between exact change and an E-ZPass lane.
Cash still counts.
New Hampshire’s turnpike system runs several of these staffed, cash-accepting plazas, including the plaza at Hampton.
A Massachusetts driver on the Mass Pike or the Tobin Bridge doesn’t stop for anything.
The state tore out its last toll booths years ago and switched to all-electronic tolling, reading transponders and plates at highway speed under overhead gantries.
The toll itself isn’t the giveaway.
It’s whether the car in front of you stops moving to pay it.
4. Left-Lane Camping
Massachusetts and New Hampshire both tell drivers to clear out of the left lane once they’re done passing.
On I-93 through Massachusetts, sitting in the left lane below the speed of traffic can get you pulled over.
State law makes the left lane a passing lane, not a cruising lane.
Massachusetts State Police run dedicated patrols to write left-lane tickets, especially around holiday weekends.
The fine runs $105.
Many Massachusetts drivers know the rule exists.
It shows: On a crowded highway, the left lane usually keeps moving.
New Hampshire has the same kind of law on the books.
Under New Hampshire’s left-lane statute (RSA 265:16), a driver who blocks traffic by camping in the left lane can be fined $50.
The rule has stood since 2019.
It rarely makes headlines.
New Hampshire hasn’t built anything like Massachusetts’s holiday-weekend crackdowns.
Follow a car camped in the left lane long enough on either highway, and the plate will usually tell you which side of the border trained that driver.
Both states wrote the same rule.
Only one keeps reminding drivers it’s real.
5. Wipers Without Headlights
Massachusetts drivers on Route 3 split into two habits the moment rain starts.
Some flick on headlights the second the wipers go on.
Others don’t.
Massachusetts law spells out the first habit directly.
Whenever a driver uses windshield wipers because of rain, snow, or fog, headlights have to be on too.
It’s the law.
New Hampshire’s vehicle code requires headlights from sunset to sunrise and in conditions of low visibility, but it doesn’t tie the requirement to wipers by name the way Massachusetts does.
That difference in wording plays out on the road: A wiper-triggered headlight is a near-reflex for Massachusetts drivers, and a mixed habit for New Hampshire drivers.
6. Seat Belt Gap
Massachusetts drivers buckle up more often than their New Hampshire counterparts, and the pattern holds at any red light on either side of the border.
Massachusetts requires drivers and passengers age 13 and up to buckle up, under Chapter 90, Section 13A of the state’s General Laws.
New Hampshire requires it only for drivers and passengers under 18.
Adults are exempt.
An adult behind the wheel there can legally leave the belt unbuckled.
Survey data from the National Highway Traffic Safety Administration reflects it, with New Hampshire posting one of the lowest observed seat belt rates in the country.
New Hampshire’s Buckle-Up Loophole
New Hampshire’s seat belt law only ever covered drivers and passengers under 18.
Lawmakers have taken up a general adult mandate more than once, and voted it down every time.
That makes it the only state in the country with no seat belt law at all for adults in the front seat.
Massachusetts, by contrast, enforces its 13-and-up rule as a secondary offense.
That means an officer can add the ticket onto a stop made for something else, but can’t pull a car over for the unbuckled belt alone.
7. Annual Inspection Errand
Massachusetts drivers make an actual trip once a year: Haul the car to an inspection station, wait for the test, drive off with a new sticker on the windshield.
The state’s annual safety and emissions inspection program has been part of owning a car there for decades.
Skip it, and the car can’t legally stay registered on the road.
New Hampshire drivers made that same trip every year, until state lawmakers ended the requirement.
A two-year state budget signed by Governor Kelly Ayotte did away with the mandatory program, and New Hampshire suspended annual inspections in February 2026.
New Hampshire drivers haven’t had a station to report to since.
The program’s fate is still moving through federal review.
The Environmental Protection Agency proposed approving the state’s plan in August 2026, opening a public comment period ahead of a final decision expected by the end of the year.
Until that decision lands, a New Hampshire windshield with no sticker at all, on a car old enough that one would be expected, stays a tell heading north.

8. Zipper Lane
Drive the Southeast Expressway into Boston during rush hour, and a Massachusetts commuter will already be watching for a lane many out-of-staters never notice.
MassDOT reverses a lane of I-93's "zipper lane" to flow with the morning and evening commute.
A machine physically drags the concrete barrier to the other side of the road, twice a day.
Locals time their merges around it without thinking.
New Hampshire skips it.
The state's public works department has never reported operating a reversible, barrier-shifted commuter lane on any of its interstates.
A New Hampshire driver dropped into Boston traffic can be the one person on the road who doesn't know the barrier moved.
