Cycling safety in Maine

Crash data

1 cyclist fatalities in 2024 .

Maine has very small annual cyclist-fatality counts, so year-to-year figures are volatile and should be read as near-zero rather than a trend. IIHS Fatality Facts (2024 data, drawn from NHTSA's FARS and posted June 2026) reports 1 bicyclist death in Maine in 2024 (1% of the state's 177 traffic deaths). For the prior year, NHTSA's Traffic Safety Facts 2023 fact sheet (DOT HS 813 739, Table 6, FARS 2023 Annual Report File) recorded 0 pedalcyclist fatalities in Maine, making it one of only four states (with Alaska, North Dakota, and South Dakota) with zero that year. cyclistInjuries is set to null because no clean, official statewide annual bicyclist-injury count for Maine was confirmed in these sources (MaineDOT reports vulnerable-road-user crash data in aggregate rather than a single published bicyclist-injury total).

Cycling rules in Maine

Helmets: Bicyclists under 16 must wear a properly fitted, fastened bicycle helmet (as operator or passenger). There is no statewide helmet mandate for riders 16 and older. (source)
Passing distance (3-foot law): A motorist overtaking a bicyclist must leave at least 3 feet of clearance; if that space isn't available they must wait to pass. Drivers may cross the centerline in a no-passing zone to pass a cyclist when it is safe, and a driver who has passed may not turn right unless it can be done safely. (source)
Sidewalk riding: Sidewalk riding is generally allowed and legal in Maine unless a local municipality/ordinance prohibits it, so rules vary by town - check the local ordinance where you ride. (source)
E-bikes: Maine recognizes the standard 3-class system (Class 1 pedal-assist to 20 mph, Class 2 throttle to 20 mph, Class 3 pedal-assist to 28 mph). E-bikes are treated much like bicycles; any operator or passenger under 16 must wear a helmet, no one under 16 may operate a Class 2 or Class 3 e-bike, and a Class 3 e-bike must have a speedometer. Class 3 e-bikes are restricted on separate bike paths unless the path is within a roadway or specifically authorized. (source)
Lights and reflectors at night: When riding at night a bicycle must have and use a headlight, plus a rear reflector and foot/ankle/pedal reflectors. Bikes must also have functional brakes. (source)
Direction of travel / where to ride: Ride with traffic, not against it. Bicyclists ride as far to the right as is practicable, but may legally take more of the lane to turn left, go straight where a right turn is also allowed, pass, or avoid obstacles and hazards. Cyclists may use bike lanes/paths but are not required to, and are not required to ride on shoulders. (source)
Stop-as-yield (Idaho stop): Maine has NOT adopted a stop-as-yield / 'Idaho stop' law. Bicyclists have the same rights and responsibilities as drivers and must obey traffic control, including making full stops at red lights and stop signs and yielding to pedestrians in crosswalks. (source)

Cities and counties often add their own rules (for example, where you can ride on sidewalks or boardwalks). Check the local ordinance for the specific town you're visiting.
