FAQ: Driving in Seattle
Do I need a car in Seattle?
For the city itself, not necessarily. Downtown, Capitol Hill, and nearby neighborhoods are served by light rail and buses. A car is valuable for day trips to Mount Rainier, the San Juan Islands ferry, or the Olympic Peninsula.
Does it really rain all the time in Seattle?
Seattle gets less total rainfall than New York or Miami, but has more rainy days (150+ per year). Rain is usually a light drizzle rather than downpours. Keep headlights on and maintain extra following distance on wet roads.
How do Washington State Ferries work for drivers?
Ferries to Bainbridge Island, Bremerton, and the San Juans carry vehicles. Arrive 30-60 minutes early (earlier in summer). Pay per vehicle at the terminal. Reservations are available and recommended for San Juan Islands routes.
What is the Good To Go pass?
Good To Go is Washington's electronic toll pass for the SR-520 bridge and other toll facilities. Without one, your plate is photographed and you're billed by mail at higher rates. Rental cars may have built-in transponders - check with your rental company.
