About speed limits in Maine
Maine holds the speed crown east of the Mississippi. In 2011 it became the first eastern state since the 1970s to post 75 mph, on the lightly traveled 100-plus miles of I-95 between Old Town and Houlton near the Canadian border. Most of the rest of I-95, including the Maine Turnpike, and I-295 around Portland carry 70 mph, easing to 50-65 mph through urbanized stretches. Off the interstate, Title 29-A sets defaults of 45 mph on open highway and 25 mph in business or residential districts and built-up areas unless a different limit is posted.
The 75 mph zone works because northern Maine is genuinely empty: long sight lines, low traffic volumes and hours between major towns. Moose collisions, not congestion, are the characteristic hazard, and nighttime drivers are advised to run below the limit through posted moose-crossing corridors in Aroostook and Penobscot counties.
In town, the 25 mph default covers business and residential districts, and municipalities may set local limits from 20 to 25 mph in compact areas with state approval. School zones are posted 15 to 25 mph when flashing, and coastal tourist towns enforce their village limits vigorously in summer.
Maine has no automated speed or red-light cameras and no active program to introduce them, so enforcement rests with the State Police and the Turnpike troop. The state's sharpest legal edge is criminal speeding: driving 30 mph or more over any limit is a Class E crime carrying a court date, potential license suspension and a criminal record rather than a simple traffic fine.
Enforcement
Maine State Police patrol I-95 and the Turnpike with radar, laser and aircraft-assisted details, while municipal officers cover the 25 mph districts. There are no speed cameras anywhere in Maine.
Tolerance
Troopers on the interstate generally let a few mph slide and focus on drivers well above the flow, but the 30-over criminal speeding line is absolute, and tolerance is minimal in work zones and coastal villages.
Speeding fines in Maine
Ordinary speeding fines start around 50 dollars and rise with speed once fees are added, with typical tickets landing between roughly 120 and 300 dollars and doubled fines in work zones. Exceeding the limit by 30 mph or more is a Class E criminal offense, not a civil violation, and can bring a suspension.
Frequently asked questions
What is the maximum speed limit in Maine?
75 mph on Interstate 95 between Old Town and Houlton, the highest limit in New England and anywhere east of the Mississippi. Most other sections of I-95 and I-295 are posted at 70 mph.
Why does Maine have the only 75 mph road in New England?
The 2011 law targeted the remote northern half of I-95, where traffic is sparse and sight lines are long, making Maine the first eastern state in decades to go above 70. No other New England state has followed, so the Old Town to Houlton stretch remains unique.
What is the residential speed limit in Maine?
25 mph by default in business or residential districts and built-up areas unless otherwise posted, and municipalities may post 20 to 25 mph in compact zones. The default on other unposted roads is 45 mph.
Does Maine use speed cameras?
No. Maine has no automated speed or red-light camera enforcement, and no statewide program is planned. Speeding is enforced by Maine State Police and local officers, and going 30 mph or more over the limit is charged as a Class E crime.
