Your health and safety are our priority. Sound Transit's operators and security staff are wearing masks, and maintenance crews are thoroughly cleaning our vehicles daily, but we need your help too. Here's what you can do to keep yourself and others safe:

  • In line with state requirements, wear a mask or cloth face covering while onboard transit and while waiting at the bus stop or station. Children under 2 or people with a disability that makes it hard to wear a face covering can still ride.
  • Take advantage of touch-free fare payment options like the Transit GO Ticket app or ORCA card.
  • Maintain a safe distance from transit operators and fellow riders.
  • Report unsanitary conditions, vandalism or anything else that makes you feel unsafe. Text or call ST Security at 206-398-5268.
  • Wash your hands frequently and don't ride if you're sick.
