Find the best car rental options in Portland to explore top-rated restaurants, events, and attractions with ease and flexibility.
Driving Requirements
Oregon law allows visitors to drive with a valid foreign license for up to 30 days. An International Driving Permit (IDP) is not legally required but is recommended if your license is not in English.
Oregon's legal minimum driving age is 16 with a valid license. Rental companies typically require drivers to be 21-25 years old, with additional fees for drivers under 25. Some companies rent to drivers 18-20 with significant surcharges.
Oregon law requires minimum liability insurance coverage. Rental companies must offer state minimum coverage. But typically provide additional optional coverage including collision damage waiver and supplemental liability. Check if your personal auto insurance or credit card provides coverage.
Most rental companies require a major credit card in the driver's name for security deposit. Debit cards may be accepted but often require additional documentation. Deposit amounts vary by company and vehicle type.
Drive on the right side of the road. Right turns on red are generally permitted after a complete stop, unless posted otherwise. Oregon has strict hands-free phone laws - handheld device use while driving is prohibited. Pedestrians have right of way at all crosswalks.
Helpful Tips
PDX on-airport rental counters are a 5-minute shuttle ride from baggage claim and usually stock the widest car selection, while downtown offices near SW Morrison can save the 18% airport concession fee and offer one-way drop-offs back to PDX at no extra charge with most major brands.
Walk a slow 360° around the car in the garage's bright lights before leaving, note any windshield chips from loose gravel on I-84 and photograph the fuel gauge. Most Portland outlets default to full-to-full, so decline prepaid fuel unless your return flight is before 6 a.m. when stations are scarce.
Google Maps works flawlessly across Portland's grid and rural Gorge routes. But download offline Oregon/Washington maps if you'll head into the Coast Range where cell coverage drops; built-in GPS is rarely worth the daily add-on when your phone already has live traffic and MAX rail crossing alerts.
Regular unleaded is the norm; Chevron and Shell clusters sit every few blocks on Powell Blvd and MLK Blvd, while downtown stations near PSU can run 15, 20 ¢ higher, fill up in inner east-side neighborhoods before returning to avoid PDX's pricier pumps.
Street parking downtown is free after 7 p.m. and all day Sunday. But meters run until 7 p.m. weekdays and cost more in the core, look for Smart Park garages for overnight stays. Residential zones like Hawthorne forbid overnight visitor parking without a permit, so confirm hotel garage access before booking.
Driving Warnings
Right-on-red is illegal throughout downtown Portland and specifically banned at all intersections along SW Morrison and SW Yamhill streets. Violation carries a $265 fine.
Portland requires studded tires to be removed by March 31st or drivers face $190 fines, while chains become mandatory on all vehicles during winter weather warnings on US-26 heading to Mount Hood.
I-5 through the Rose Quarter and I-84 eastbound from I-5 experience severe congestion from 6:30-9:30 AM and 3:30-6:30 PM on weekdays, often backing up for miles with no alternate routes.
Speed cameras operate 24/7 on NE Sandy Boulevard between NE 12th and NE 82nd, and on SW Beaverton-Hillsdale Highway, with automated tickets starting at $160 for exceeding posted limits by 11+ mph.
