Driving Requirements
Visitors from other U.S. states and most countries may drive in Maryland using their valid home license. International visitors from countries whose licenses are not printed in English are generally recommended to carry an International Driving Permit (IDP) alongside their home license, as Maryland law enforcement may request a readable document. There is no fixed statewide expiration window for foreign license use. But visitors planning an extended stay (typically beyond 60 days as a new resident) may be required to obtain a Maryland license.
Maryland law sets the minimum driving age at 16 (with a graduated license). Rental company policies are a separate matter and vary significantly: some companies rent to drivers aged 21 and over, while others accept drivers as young as 18 but typically charge a young-driver surcharge. Many major agencies require drivers to be 25 to avoid that surcharge entirely. Always confirm age requirements directly with your chosen rental company before booking.
Maryland law requires all drivers to carry minimum liability insurance coverage. Driving uninsured is a legal offense. Rental companies are required to include state-minimum liability coverage in their contracts. Renters may also be offered additional products such as a Collision Damage Waiver (CDW) or Loss Damage Waiver (LDW), which reduce your financial exposure for damage to the rental vehicle, these are rental company add-ons, not legal mandates. Check whether your personal auto insurance policy or credit card already extends coverage to rental vehicles before purchasing additional products.
Rental companies in Baltimore generally require a major credit card (not a debit card) at pickup to place a security hold, which can be several hundred dollars and is released after the vehicle is returned undamaged. Policies on debit card acceptance vary by company and location, some permit it with additional ID verification or a larger deposit, others do not accept it at all. Confirm your specific rental company's payment policy in advance to avoid issues at the counter.
Traffic in Maryland follows the right-hand side of the road. A right turn on red is generally permitted after a full stop unless a posted sign prohibits it, such signs are common in Baltimore's busy downtown intersections, so look carefully before turning. Speed camera and red-light camera enforcement is active in Baltimore City, and fines are issued to the registered owner of the vehicle, which in a rental typically means the charge is passed to the renter.
Helpful Tips
Baltimore/Washington International Thurgood Marshall Airport (BWI) has a consolidated rental facility connected by shuttle, which can add 15, 20 minutes to your pickup, city-center locations near the Inner Harbor or downtown tend to offer faster pickup if you're arriving by train or already in town, though their fleets are typically smaller and availability can be tighter on weekends.
Before accepting the vehicle, photograph all existing dents, scratches, and interior wear in good lighting and confirm damage is logged on the rental agreement, Maryland's urban rental fleets see heavy use, so undocumented prior damage is a common dispute. If your personal auto insurance or credit card covers rentals, declining the company's collision waiver is worth confirming with your provider before you get to the counter.
Google Maps works reliably throughout Baltimore and is the practical choice for most drivers, it handles the city's mix of one-way streets, the complex interchange around I-95 and I-695 (the Baltimore Beltway), and frequent construction detours well; built-in GPS units in rental cars are generally an unnecessary expense here.
Most Baltimore-area stations operate on a full-to-full fuel policy, which is typically the better deal, prepaid fuel options from rental companies are generally priced at a premium and rarely save money unless you expect to return the car nearly empty. Stations are plentiful in the suburbs and along major corridors. But Inner Harbor and Fells Point have few stations immediately nearby, so refuel before returning to dense neighborhoods.
Street parking in downtown Baltimore, Fells Point, and Federal Hill is metered and competitive, on evenings and weekends, parking garages near the Inner Harbor and Harbor East are the most reliable overnight option. Residential neighborhoods like Canton have permit zones that will result in a ticket for non-residents, so check posted signage carefully if you park away from tourist areas.
Driving Warnings
Baltimore City intersections frequently post "No Turn on Red" signs that catch visiting drivers off guard, unlike the suburban counties surrounding the city, the urban core restricts right-on-red at a large share of signalized intersections, and ignoring posted signs is a moving violation subject to a citation.
Maryland operates automated speed cameras in designated school zones throughout Baltimore City, issuing civil fines (typically around $40) mailed to the registered vehicle owner regardless of who was driving, visitors with out-of-state plates are not exempt, and the cameras are active during posted enforcement hours.
The Fort McHenry Tunnel on I-95 is Baltimore's single largest traffic bottleneck: expect severe northbound backups on weekday mornings (roughly 7, 9 AM) and southbound delays in the late afternoon (4, 7 PM); the tunnel is fully cashless-tolled, so visitors without an E-ZPass transponder are billed automatically by license plate.
Baltimore's surface streets are notorious for deep potholes that worsen significantly from February through April after freeze-thaw cycles, residential corridors in East and South Baltimore in particular can hide wheel-damaging holes, and driving at night on unfamiliar streets meaningfully increases the risk of tire or rim damage.
