Our buses and trains are fully accessible

  • ST Express buses are equipped with ramps or wheelchair lifts.
  • On Sounder train platforms, the conductor will deploy a boarding ramp to help riders get onto the train safely.
  • Link light rail trains feature level boarding. Board directly from the platform without climbing steps or using a lift or ramp.
  • On Tacoma Link, press the round accessibility symbol on the outside of the door when the train has stopped. The light rail operator will deploy a ramp to allow you to board the train.

Fare discount

Seniors (65 and older) and people with disabilities ride at a reduced rate using a Regional Reduced Fare Permit.

When boarding the bus, show your reduced fare permit to the driver. On the train, show your reduced fare permit to the conductor when asked.

Your personal care attendant can ride for free, but must board and leave with you.

Priority seating

Designated seating for senior citizens or riders with disabilities is available on all Sound Transit trains and buses. 

Finding your way around stations

Signs and other design features will help you get to and from stations and show you how to use our trains and buses. We use innovative communication tools, including art and pathways, that can guide you by sight, feel, touch or voice.

Request for Reasonable Modifications

Policy: In accordance with the Americans with Disabilities Act (ADA) and directives from the Federal Transit Administration, Sound Transit will make every effort, to the maximum extent feasible, to ensure that a person with a disability has access to, and benefits from, its services. Sound Transit will make reasonable modifications to its policies, programs, and procedures applicable to its transportation services when necessary to avoid discrimination and ensure accessibility for people with disabilities.

Reasonable modifications do have limitations and are not intended to:

  • Cause a direct threat to the health and safety of others
  • Create undue financial and administrative burdens
  • Constitute a fundamental alteration to a service
  • Not necessary to provide equal access to an Sound Transit service

Considerations when making a reasonable modification request:

  • Individuals requesting modifications shall describe what they need in order to use the service.
  • Individuals requesting modifications are not required to use the term “reasonable modification” when making a request.
  • Whenever feasible, requests for modifications shall be made and determined in advance, before the transportation provider is expected to provide the modified service, for example, during the paratransit eligibility process, through customer service inquiries, or through the entity's complaint process.
  • Where a request for modification cannot practicably be made and determined in advance (e.g., because of a condition or barrier at the destination of a paratransit or fixed route trip of which the individual with a disability was unaware until arriving), operating personnel of the entity shall make a determination of whether the modification should be provided at the time of the request. Operating personnel may consult with the entity's management before making a determination to grant or deny the request.

The request must identify the modification needed in order to use the service. Whenever feasible, please make the request in advance, before the modification is needed to access the service.

Within the scope of the ADA and reasonable modification, if Sound Transit denies a request it will make every effort, to the maximum extent feasible, to ensure that a person with a disability has access to, and benefits from, its services.

Procedure: To request reasonable modifications based on a disability please use the Reasonable Modification Request Form, or contact 800-201-4900 / TTY Relay 711 or email

You may be asked to complete a request form. Sound Transit will review the request in accordance with its reasonable modification plan. Sound Transit strives to respond, in writing, to each request within 15 calendar days.

All the information involved with this process will be kept confidential.
