  What is the best time to leave to avoid traffic in San Francisco?,Generally before 6:30 a.m. or after 9:30 a.m. in the morning, and outside 3:30–7:00 p.m. in the evening — and on a bridge commute, even 15 minutes earlier makes an outsized difference.
  When is San Francisco rush hour?,Roughly 6:30–9:30 a.m. and 3:30–7:00 p.m., with the Bay Bridge approaches backing up before and beyond those windows.
  How bad is Bay Area traffic compared to other cities?,San Francisco drivers lost roughly 49 hours a year in the 2025 INRIX data — fewer total hours than LA or Chicago, but INRIX names SF among the nation's major bottlenecks: the delay is concentrated on a few corridors at peak hours.
  What is the worst road in the Bay Area?,The Bay Bridge corridor — the toll plaza, metering lights and the MacArthur Maze — is the signature chokepoint, with 101 through the city and the 580/680 East Bay commutes close behind.
  Why is Bay Bridge traffic so bad?,The bay funnels an enormous share of regional travel onto one span with metering lights and a complex interchange feeding it — so demand outstrips the bridge every peak, and any incident multiplies the backup.
  How do I find the best time to leave for my Bay Area commute?,Use a leave-time commute app that reads your actual route — not only a live map. BoardSpy recommends when to leave for your Bay Area commute route, sends pre-departure traffic and weather alerts, and tracks on-time performance and best and worst traffic days.
