Introduction
Driving in Maryland offers a diverse experience, from the bustling urban corridors of Baltimore and the Washington D.C. suburbs to the serene coastal highways of the Eastern Shore and the mountainous roads of Western Maryland. Tourists will find that driving is often the most practical way to explore the state's rich historical sites, including Annapolis and Fort McHenry. Traffic moves on the right side of the road, and the steering wheel is on the left side of the vehicle, which is familiar to most North American drivers but may require adjustment for visitors from the United Kingdom, Australia, or Japan. While the state's major highways are generally well-maintained, traffic congestion around the Baltimore-Washington metropolitan area can be intense during peak commuting hours. The local currency is the United States Dollar, and all transactions, including tolls and parking fees, are conducted in this currency. Most tourists coming from abroad find renting a car straightforward, especially at Baltimore/Washington International Thurgood Marshall Airport.Is It Easy to Drive There?
Driving in Maryland is relatively easy for tourists accustomed to North American road systems, but presents some challenges in urban areas. The road network is logically laid out, with Interstate highways like I-95, I-70, and I-495 providing efficient long-distance travel. Road quality is generally good, though potholes can appear after winter months. The primary challenge for visitors is the notorious traffic congestion around the Capital Beltway, especially during rush hours from 7:00 AM to 9:30 AM and 4:00 PM to 6:30 PM. Maryland drivers are known for assertive driving styles, and out-of-state visitors should be prepared for aggressive lane-changing and high speeds on interstates. Rural roads in Western Maryland and the Eastern Shore offer a more relaxed driving experience.Driving Side
Maryland follows right-hand traffic rules, meaning vehicles drive on the right side of the road and overtake on the left. The steering wheel is positioned on the left side of the vehicle, consistent with the North American standard. For tourists arriving from countries where driving is on the left, such as the United Kingdom or Ireland, it is crucial to remain vigilant at intersections, especially when making turns, as the natural instinct to look in the wrong direction can lead to dangerous situations. Always yield to vehicles already in a roundabout and remember that on multi-lane roads, the left lane is designated for passing.Speed Limits
| Road Type | Speed Limit | Notes |
|---|---|---|
| Urban Areas | 30 mph (48 km/h) | Standard limit in residential and business districts unless otherwise posted. |
| Rural Roads | 50-55 mph (80-88 km/h) | Common on undivided two-lane highways outside urban areas. |
| Expressways | 55-65 mph (88-105 km/h) | Divided highways with at-grade crossings; limit varies by location. |
| Interstate Highways | 65-70 mph (105-113 km/h) | Maximum 70 mph on designated rural interstates; 65 mph in suburban areas. |
Speed enforcement is strict, particularly in work zones where fines are doubled. Speed cameras are used in school zones and some highway work zones.
Seat Belt Laws
Maryland law requires all occupants of a motor vehicle to wear a seat belt regardless of their seating position. The driver is responsible for ensuring that all passengers under the age of 16 are properly restrained. Front seat occupants must wear a seat belt at all times while the vehicle is in motion, and failure to do so is a primary offense, meaning law enforcement can stop a vehicle solely for a seat belt violation. Rear seat passengers aged 16 and older are also required to wear seat belts, though this is a secondary offense for adults. Children under 8 years old must be secured in an appropriate child safety seat unless they are taller than 4 feet 9 inches. The fine for a seat belt violation is $83 (approximately $83 USD) per unrestrained occupant.Child Seat Rules
Children under 8 years of age must ride in a federally approved child safety seat unless they are 4 feet 9 inches tall or taller. Children under 2 years of age must be secured in a rear-facing child restraint system until they reach the maximum weight or height limit allowed by the manufacturer of the seat. Children between 2 and 4 years old may transition to a forward-facing seat with a harness once they outgrow the rear-facing seat. Children aged 4 to 8 who are under 4 feet 9 inches must use a booster seat to ensure proper seat belt fit. ISOFIX (LATCH) anchor systems are required in vehicles manufactured after 2002 and are recommended for installing child seats. The fine for violating child seat laws can exceed $50 (approximately $50 USD) for a first offense.Drink Driving Laws
The legal blood alcohol concentration limit for drivers aged 21 and older in Maryland is 0.08%. For commercial drivers, the limit is reduced to 0.04%, and for drivers under 21, a zero-tolerance policy applies with a limit of 0.02%. Driving under the influence carries severe penalties, including a maximum fine of $1,000 (approximately $1,000 USD) for a first offense and up to $5,000 (approximately $5,000 USD) for a third offense. A first DUI conviction results in a minimum 6-month license suspension, and a second offense leads to a one-year suspension. Refusing a chemical test triggers an automatic 270-day license suspension. Aggravated factors, such as having a minor in the vehicle or a BAC of 0.15% or higher, result in enhanced penalties.Mobile Phone Rules
Maryland prohibits the use of a handheld mobile phone while driving. This includes texting, dialing, or browsing the internet. Drivers may use hands-free devices such as Bluetooth headsets, speakerphone functions, or built-in vehicle systems. GPS navigation apps are permitted provided the device is mounted and not held in the hand while driving. The fine for a first-time texting-while-driving violation is $70 (approximately $70 USD), and a subsequent offense can result in a $110 fine (approximately $110 USD) and one point on the driver's license. These restrictions are enforced as primary offenses, allowing law enforcement to stop a driver solely for mobile phone use.Required Documents
To legally drive in Maryland, drivers must carry a valid driver's license from their home country or state. While an International Driving Permit is not legally required for short-term visitors, it is strongly recommended for those with licenses not in English. A valid passport is required for identification purposes for international tourists. If renting a vehicle, carry the rental agreement and proof of insurance at all times. The vehicle registration document must be in the car if driving a private vehicle. Proof of insurance meeting Maryland's minimum liability requirements ($30,000 bodily injury per person, $60,000 per accident, and $15,000 property damage) is mandatory.International Driving Permit (IDP)
International visitors driving in Maryland do not need an International Driving Permit if their home country driver's license is in English or accompanied by a certified English translation. Tourists can legally drive with a valid foreign license for up to one year from their date of entry into the United States. Drivers from countries that are part of the Inter-American Driving Permit convention or the 1949 Geneva Convention may benefit from carrying an IDP as a supplementary form of identification. While Maryland law enforcement generally accepts foreign licenses, an IDP helps bridge language barriers during traffic stops and simplifies the rental car process. IDPs must be obtained in the driver's home country before traveling and cannot be issued in the United States.Road Signs
Common road signs in Maryland follow the standard Manual on Uniform Traffic Control Devices. The red octagonal stop sign and red-and-white triangular yield sign are standard. Speed limit signs are white with black lettering in a rectangular shape. No entry signs use a red circle with a white horizontal bar. Roundabout signs are circular with arrows indicating the flow of traffic. School zones are marked with fluorescent yellow-green pentagonal signs. Work zones use orange diamond-shaped signs. Maryland-specific signs include blue evacuation route markers for coastal areas and brown signs indicating scenic byways such as the Chesapeake Country Scenic Byway.Toll Roads
Maryland operates an extensive network of toll roads, bridges, and tunnels, primarily managed by the Maryland Transportation Authority. The state uses a fully electronic toll collection system called E-ZPass, and cash is no longer accepted at most toll facilities. Drivers without an E-ZPass transponder are billed through a video tolling system that photographs the license plate and mails an invoice. Key toll facilities include the Fort McHenry Tunnel and John F. Kennedy Memorial Highway on I-95, the Chesapeake Bay Bridge on US-50/301, and the Intercounty Connector. Tolls for passenger vehicles on I-95 range from approximately $4 (approximately $4 USD) to $12 (approximately $12 USD) depending on the specific crossing. Visitors can register for a temporary E-ZPass or expect to receive a mailed toll invoice.Fuel Stations
Fuel stations are plentiful throughout Maryland, especially along major highways and in urban areas. Regular unleaded petrol (87 octane), mid-grade (89 octane), and premium (91-93 octane) gasoline are widely available. Diesel fuel is common at truck stops and many major station chains. Compressed natural gas and liquefied petroleum gas are available at select locations. Electric vehicle charging stations are increasingly common, with networks like Tesla Superchargers, Electrify America, and ChargePoint available at shopping centers, rest areas, and dedicated charging hubs. Most fuel stations operate 24 hours along interstates, while rural stations may close by 10:00 PM. As of mid-2026, the average price for regular unleaded fuel is around $3.40 per gallon (approximately $3.40 USD).Parking Rules
Parking regulations in Maryland vary significantly by jurisdiction. In Baltimore and other urban centers, metered parking typically costs between $1.00 (approximately $1.00 USD) and $3.00 (approximately $3.00 USD) per hour, with time limits strictly enforced. Many meters now accept credit cards and mobile payment apps like ParkMobile. Residential areas often require a permit for parking longer than two hours. Parking in a fire lane or in front of a fire hydrant carries fines starting at $77 (approximately $77 USD). Unauthorized parking in a space reserved for persons with disabilities results in a fine of $140 to $500 (approximately $140 USD to $500 USD). In downtown areas, garage parking can cost $15 to $30 (approximately $15 USD to $30 USD) per day. Always check for street sweeping signs to avoid towing.Roundabout Rules
At roundabouts in Maryland, vehicles already circulating within the circle have the right-of-way. Drivers entering a roundabout must yield to traffic approaching from the left and enter only when there is a safe gap. Multi-lane roundabouts require drivers to select the appropriate lane before entering: use the right lane for the first exit, and the left lane for continuing around or taking a later exit. Always signal your intent to exit the roundabout by using your right turn signal after passing the exit prior to the one you intend to take. Never stop inside a roundabout except to avoid a collision, and do not change lanes while in the circle.Winter Driving
Winter driving in Maryland can be challenging, particularly in the western regions including Garrett and Allegany counties, where significant snowfall is common. While snow tires are not legally mandated by state law, they are strongly recommended for travel in mountain areas during winter months. Tire chains may be required on certain mountainous routes during severe snow conditions, as indicated by electronic message boards. The Maryland State Highway Administration maintains a fleet of snow plows and salt spreaders that prioritize interstates and primary routes. Drivers should carry an emergency kit containing blankets, a flashlight, and non-perishable food. During major snow events, the state may declare a snow emergency, restricting parking on designated snow emergency routes.Low Emission Zones
Maryland does not currently have a mandatory statewide low emission zone or congestion charge zone for passenger vehicles. However, the state participates in the federal Clean Air Act requirements, and vehicles must pass an emissions inspection every two years in certain counties, including Baltimore City and Anne Arundel, Montgomery, and Prince George's counties. Diesel vehicles are subject to visible smoke opacity testing. Electric vehicles are encouraged through incentives and access to High Occupancy Vehicle lanes. The Maryland Department of the Environment monitors air quality, but tourists in standard passenger vehicles face no special restrictions or registration requirements for entering urban areas.Traffic Fines
| Violation | Fine (Local Currency) | Approximate USD |
|---|---|---|
| Speeding (1-10 mph over limit) | $80 - $160 | $80 - $160 USD |
| Speeding (11-20 mph over limit) | $160 - $290 | $160 - $290 USD |
| Handheld Phone Use (First Offense) | $70 | $70 USD |
| Seat Belt Violation | $83 | $83 USD |
| DUI (First Offense) | Up to $1,000 | Up to $1,000 USD |
| Running a Red Light | $140 | $140 USD |
| Parking in Fire Lane | $77 | $77 USD |
| Failure to Yield to Pedestrian | $130 | $130 USD |

Renting a Car
Renting a car in Maryland provides the greatest flexibility for exploring the state. The minimum rental age is typically 21, though drivers aged 21 to 24 often incur a young driver surcharge of approximately $25 (approximately $25 USD) per day. A major credit card in the driver's name is almost universally required for the security deposit. Standard insurance options include a Collision Damage Waiver, which typically costs $15 to $25 (approximately $15 USD to $25 USD) per day, and Supplemental Liability Insurance. Most rental companies use a full-to-full fuel policy, requiring you to return the vehicle with a full tank. Airport pickup is available at Baltimore/Washington International Thurgood Marshall Airport, where major companies like Hertz, Avis, Enterprise, and Budget operate on-site. One-way rentals between Maryland locations and other states are generally allowed but may incur a drop-off fee. Average daily rental rates for a compact car range from $50 to $80 (approximately $50 USD to $80 USD), while SUVs start at around $90 (approximately $90 USD) per day.Frequently Asked Questions
