Introduction
Driving in Maine offers a quintessential New England experience, with scenic coastal routes, dense forests, and charming small towns. Traffic moves on the right-hand side of the road, with the steering wheel positioned on the left side of vehicles. For tourists, renting a car is the most practical way to explore the state's vast geography, from Acadia National Park to the remote North Woods. The United States dollar ($) is the local currency, and all transactions, including tolls and parking, are processed in this currency. Maine's road network includes interstate highways, state routes, and rural roads that wind through picturesque landscapes. While urban areas like Portland experience moderate traffic, most of the state offers relaxed driving conditions. International visitors should familiarize themselves with local traffic laws, which are enforced by the Maine State Police and local law enforcement agencies.Is It Easy to Drive There?
Driving in Maine is generally straightforward and enjoyable for tourists, thanks to well-maintained roads and clear signage. The primary challenge is navigating rural two-lane roads, which can be narrow and winding, particularly in coastal and mountainous regions. During peak tourist seasons, especially summer and fall foliage months, popular destinations like Bar Harbor and Boothbay Harbor experience increased traffic congestion. Wildlife, particularly deer and moose, pose a significant hazard, especially at dawn and dusk. Winter driving presents additional challenges, with snow, ice, and reduced visibility common from November through March. Overall, tourists with basic driving competence will find Maine accessible and rewarding.Driving Side
In Maine, all vehicles are driven on the right-hand side of the road. The steering wheel is located on the left side of the vehicle, consistent with all other U.S. states. Overtaking is performed on the left, and drivers must yield to vehicles already in a traffic circle. For visitors from countries where driving is on the left, extra caution is advised at intersections and when entering roadways. Always look left first before pulling out, as oncoming traffic will approach from that direction.Speed Limits
| Road Type | Speed Limit | Notes |
|---|---|---|
| Urban/Residential Areas | 25 mph | Unless otherwise posted; school zones reduced to 15-20 mph during designated hours |
| Rural Two-Lane Roads | 45-55 mph | Default is 45 mph unless posted higher; many rural routes are posted at 50-55 mph |
| State Highways | 55 mph | Standard for most undivided state highways |
| Interstate Highways (Rural) | 70-75 mph | I-95 north of Bangor is posted at 75 mph; southern sections are 70 mph |
| Interstate Highways (Urban) | 55-65 mph | Reduced limits through Portland, Augusta, and Bangor metropolitan areas |
Speed limits are strictly enforced by the Maine State Police using radar and laser devices. Fines double in active work zones when workers are present. Variable speed limits may apply during inclement weather on some highways.
Seat Belt Laws
Maine law requires all vehicle occupants to wear seat belts. The driver and all front-seat passengers must be properly restrained at all times. All passengers under 18 years of age must wear a seat belt regardless of seating position. Maine enforces a primary seat belt law, meaning law enforcement can stop a vehicle solely for a seat belt violation. The fine for a seat belt violation is $50 for a first offense. Rear-seat adult passengers aged 18 and over are not required by law to wear seat belts, though it is strongly recommended. Vehicles manufactured with seat belts must have them in working order. Exemptions exist for individuals with a physician-signed medical waiver and for rural mail carriers during delivery.Child Seat Rules
Maine child passenger safety laws require children under 2 years of age to be secured in a rear-facing car seat until they reach the manufacturer's height and weight limits. Children aged 2 to 4 years must use a forward-facing car seat with a harness. Children under 8 years of age and under 80 pounds must use a booster seat, unless they are at least 4 feet 9 inches tall. Children aged 8 to 17 must wear a seat belt. All car seats and booster seats must be installed according to manufacturer instructions and comply with federal motor vehicle safety standards. Maine law permits the use of ISOFIX (LATCH) systems for compatible child restraints. The fine for a child restraint violation is $50 for a first offense, though this may be waived if the violator obtains a child safety seat within seven days.Drink Driving Laws
Maine's legal blood alcohol concentration (BAC) limit is 0.08% for drivers aged 21 and over. For commercial vehicle operators, the limit is 0.04%. Maine has a zero-tolerance policy for drivers under 21, with a BAC limit of 0.02%. Operating Under the Influence (OUI) penalties are severe. A first offense OUI conviction carries a minimum fine of $500, a 150-day license suspension, and up to 364 days in jail. Refusal to submit to a chemical test results in an automatic 275-day administrative license suspension. Aggravating factors, such as a BAC of 0.15% or higher, or having a passenger under 21, result in enhanced penalties including mandatory minimum jail time. Maine also imposes a $1,000 reinstatement fee for suspended licenses.Mobile Phone Rules
Maine law prohibits all drivers from using handheld mobile phones while operating a motor vehicle. Texting while driving is illegal for all drivers. Adult drivers aged 18 and over may use hands-free devices, including Bluetooth headsets and in-vehicle communication systems, provided the device does not require manual handling. GPS devices may be used if mounted on the dashboard or windshield in a location that does not obstruct the driver's view. Drivers under 18 are completely prohibited from using any mobile phone or electronic device while driving, even in hands-free mode. The fine for a first handheld device violation is $50, while a first texting violation carries a minimum fine of $310. Subsequent offenses within three years result in higher fines.Required Documents
To drive legally in Maine, you must carry the following documents at all times while operating a vehicle: a valid driver's license from your country of residence (an International Driving Permit is recommended for non-English licenses but not legally required), a valid passport or government-issued photo identification for identification purposes, the vehicle registration document if driving your own vehicle, the rental agreement and proof of insurance if operating a rental car, and proof of financial responsibility (insurance card) meeting Maine's minimum liability coverage of 50/100/25 (bodily injury $50,000 per person, $100,000 per accident, property damage $25,000).International Driving Permit (IDP)
Maine does not legally require an International Driving Permit (IDP) for foreign visitors holding a valid driver's license from their home country, provided the license is in English or is accompanied by an accurate English translation. However, an IDP is strongly recommended, particularly for licenses not issued in English, as it provides a standardized translation recognized by law enforcement agencies. Visitors may drive in Maine with their foreign license for up to one year from their date of entry into the United States. An IDP cannot be issued after arrival in the U.S.; it must be obtained in the driver's home country before travel. The permit serves as a supplement to, not a replacement for, the original driver's license.Road Signs
Maine road signs follow the U.S. Department of Transportation Manual on Uniform Traffic Control Devices. Standard signs include red octagonal STOP signs, red and white inverted triangle YIELD signs, rectangular white SPEED LIMIT signs with black lettering, red circle with white horizontal bar DO NOT ENTER signs, and yellow circular advance warning signs for roundabouts (traffic circles). Diamond-shaped yellow warning signs indicate curves, intersections, pedestrian crossings, and animal crossings. Orange signs denote construction zones. Green guide signs indicate exits and distances on highways. Brown signs mark recreational and cultural sites. Blue signs indicate motorist services. Notably, Maine features yellow MOOSE WARNING signs with a silhouette of a moose, critical for rural highway sections.Toll Roads
Maine has a single major toll road, the Maine Turnpike, which is designated as Interstate 95 between Kittery and Augusta and Interstate 295 between Portland and Gardiner. The Maine Turnpike operates on an electronic toll collection system called E-ZPass, which is accepted throughout the northeastern United States. Cash is also accepted at toll plazas on the turnpike. Toll rates vary by distance traveled and vehicle class. For a standard two-axle passenger vehicle, the full-length trip costs approximately $8.00 if paying with cash. E-ZPass users receive a discounted rate. Visitors can open a temporary E-ZPass account or pay cash at designated lanes. There are no other toll roads in the state of Maine outside the Maine Turnpike system.Fuel Stations
Fuel stations are readily available throughout Maine's populated areas and along major highways, though they become sparse in the vast northern wilderness regions such as Aroostook County and the North Maine Woods. Regular unleaded petrol (gasoline) and diesel fuel are widely available. Premium unleaded petrol is also common. EV charging stations are increasingly available, particularly along the I-95 corridor, in Portland, and near Acadia National Park, with networks including Tesla Superchargers and ChargePoint. Many rural stations operate on limited hours, often closing by 9:00 PM, and some are closed on Sundays. As of mid-2026, the average price for regular unleaded petrol in Maine is approximately $3.55 per gallon. Diesel averages around $4.10 per gallon.Parking Rules
Parking regulations in Maine vary by municipality. In downtown Portland, on-street metered parking costs approximately $2.00 per hour, payable via coins, credit cards, or the Passport Parking mobile app. Residential neighborhoods may require resident parking permits, and unauthorized vehicles face fines. In coastal tourist towns like Bar Harbor and Camden, parking can be scarce during summer months, with paid lots charging $10.00 to $20.00 per day. Many state parks and beaches charge day-use parking fees of $5.00 to $10.00. Winter parking bans are common in urban areas to facilitate snow removal; vehicles left on the street during a declared ban may be towed at the owner's expense. Illegally parked vehicles face fines ranging from $25.00 for expired meters to $150.00 for parking in fire lanes or accessible spaces without proper permits.Roundabout Rules
Roundabouts in Maine follow standard right-of-way rules. Vehicles already circulating within the roundabout have priority. Approaching drivers must yield to traffic coming from the left before entering the circle. Drivers must use the right turn signal when exiting the roundabout. Lane selection before entering is critical: use the left lane for left turns or U-turns, and the right lane for right turns or going straight (unless otherwise marked). Large vehicles may need to use both lanes. Maine has been increasingly replacing traditional intersections with roundabouts for safety and traffic flow improvements. Never stop inside a roundabout except to avoid a collision.Winter Driving
Winter driving in Maine requires preparation and caution, as conditions can be severe from November through March. Maine law does not mandate the use of snow tires, but they are highly recommended for safe winter travel, particularly on untreated rural roads. Studded tires are permitted from October 2 to May 1. Tire chains are legal for use when road conditions warrant, though they must not damage the road surface. All-season tires may be insufficient during heavy snow events. Drivers should carry emergency supplies including blankets, a flashlight, jumper cables, a snow shovel, and sand or kitty litter for traction. The Maine Department of Transportation maintains a 511 traveler information system providing real-time road condition updates.Low Emission Zones
Maine does not have any designated low emission zones, ultra-low emission zones, or congestion charging zones as found in European cities. There are no restrictions on vehicle types based on emissions standards for entering any cities or regions within the state. All gasoline, diesel, and electric vehicles may travel freely throughout Maine. However, the state of Maine participates in the Clean Cars program, which aligns with California's vehicle emission standards, requiring new vehicles sold in the state to meet stricter emission requirements. This does not affect tourists driving their own or rental vehicles. The state encourages eco-friendly transportation and has been expanding EV infrastructure to support electric vehicle travel.Traffic Fines

| Speeding (1-10 mph over limit) | $114 - $199 |
| Speeding (11-20 mph over limit) | $199 - $285 |

All fines are in United States dollars ($). Fines may vary by specific location and court jurisdiction. Additional court surcharges and administrative fees may apply.
Driving Tips for Tourists
1. Watch for moose and deer, especially at dawn and dusk on rural roads; moose collisions are often fatal due to their height and weight. 2. Maintain a full fuel tank when traveling in northern and western Maine, as gas stations can be over 50 miles apart. 3. In winter, keep an emergency kit in your vehicle including blankets, food, water, and a charged phone. 4. Be aware that many rural roads are unpaved and may be graded dirt or gravel; reduce speed accordingly. 5. During fall foliage season, be cautious of tourists stopping suddenly for photographs on scenic roads. 6. Always carry cash for tolls if you do not have an E-ZPass transponder on the Maine Turnpike. 7. Obey school bus stopping laws; you must stop in both directions on undivided roads when a school bus has its red lights flashing. 8. Coastal fog can reduce visibility dramatically without warning; use low-beam headlights in foggy conditions. 9. Plan your route carefully in advance, as cellular service is unreliable in many rural and mountainous areas of the state.Renting a Car
Renting a car in Maine offers the greatest flexibility for exploring the state. The minimum rental age is 21 at most agencies, though drivers aged 21 to 24 typically incur a young driver surcharge of approximately $25.00 to $35.00 per day. A major credit card in the driver's name is required for the security deposit; debit cards may be accepted with additional verification at some locations. Rental agencies offer Collision Damage Waiver (CDW), Loss Damage Waiver (LDW), and supplemental liability insurance, which are strongly recommended unless your personal auto insurance or credit card provides equivalent coverage in the United States. The standard fuel policy is full-to-full, meaning you receive the car with a full tank and must return it full. Average daily rental rates for a standard sedan range from $50.00 to $80.00, while SUVs suitable for rural exploration range from $80.00 to $120.00 per day. One-way rentals between different locations within Maine are generally permitted but may incur a drop-off fee. Airport pickup is available at Portland International Jetport (PWM) and Bangor International Airport (BGR).Frequently Asked Questions
