Driving around San Diego Airport – Road Rules, Traffic & Local Tips
Driving in San Diego is generally straightforward and relaxed, especially compared to larger cities like Los Angeles. Roads are in good condition, well signposted, and locals tend to drive courteously but quickly.
Vehicles drive on the right-hand side, and nearly all rental cars are automatic. Speed limits are posted in miles per hour (mph):
25–35 mph in residential and city streets
45–55 mph on larger roads and boulevards
65–70 mph on highways and interstates (like I-5, I-8, and I-805)
San Diego's freeway system is efficient but can become congested during rush hours (7–9 AM and 3:30–6:30 PM). Traffic apps like Google Maps or Waze are helpful for navigating alternate routes and avoiding delays. The city's freeway signage is clear, and GPS works reliably across the region.
Right turns on red lights are allowed unless otherwise indicated. Pedestrians have the right of way at marked and unmarked crosswalks, and jaywalking is strictly enforced downtown.
Parking is generally easier than in larger metros. Many beaches, parks, and shopping centers offer free or low-cost parking, but in areas like downtown, Hillcrest, or Pacific Beach, expect to use paid street parking, metered zones, or parking garages. Always check signage — violations can result in steep fines or towing.
Fuel stations are widely available and typically self-service. Credit and debit cards are accepted, but if you're visiting from abroad and a ZIP code is required, you can prepay inside the station with cash.
If you're driving near the U.S.–Mexico border, especially toward Tijuana, be sure to confirm with your rental company whether cross-border travel is permitted. Some agencies allow it with added insurance, while others do not.
