Eligibility for all Carpool Permits 

Why do I have to live outside of a certain distance from downtown to qualify for a permit?
The intent of the carpool program is to provide carpool options for those who do not have easy access to public transportation. The area in gray has been identified as an area widely serviced by Trimet, and residents in this area are encouraged to use Trimet services. Click here to view the ineligible zone  

Is there a minimum number of people I need to carpool with to qualify?
Yes, there is a 2-person minimum.

What are the age restrictions for my carpool partners?
Carpool members must be at least 14 years old to qualify as a member of your carpool. All carpoolers must be Licensed Drivers (does not apply for student between the age of 14 to 18)

Can you explain more about travel requirements?
All members of the carpool must commute together and place of employment must be in to the Downtown Meter District or the Lloyd Meter District at least four days each week, both ways. The commute route must make common sense, and the carpool members must share at least 50% of the commute route together.

  • Qualifying Example: DJ and Lori commute in from Gresham five days a week. DJ is the driver, and picks up Lori, who lives four blocks south of her, before they travel west to the Lloyd District. DJ drops Lori off at the Convention Center where Lori works, and DJ goes on to her job at the Moda Center. This is a qualifying example because Lori and DJ carpool at least four days a week, they both work in the same meter district, and they share at least 50% of the route commute.
  • Non-Qualifying Example: Glen and Nicole commute together twice a week from their house in Ladd's Addition. They both work for the same company in downtown. This is not a qualifying trip because they do not commute together at least four times a week, and they also live within the ineligibility boundary.
  • Non-Qualifying Example: Colleen, Grant, and Anto carpool together from the West Hills. They carpool together five days a week. Colleen drops Grant and Anto off on NW 23rd where they work, then Colleen drives to PSU where she works. This is not a qualifying trip because all carpool members must work/go to school in the same meter district.


Do you verify that I work/go to school within the district I apply?
Yes, employment verification is required prior to any issuance of permits. If employment cannot be verified over the telephone by your firm's local human resources department, applicants must provide written employment verification and specific work hours on company letterhead issued from the respective personnel office. Carpool participants attending school (college, high school, or special trade schools) must attach enrollment verification and school hours from their school. PBOT reserves the right to audit this information at any time while your permit is still valid. 

Do you verify that I am carpooling with the people on my permit application?
Yes, to ensure the system is not being abused, PBOT may contact the people you list on your carpool application to verify they are still a part of your carpool.

If I leave the carpool program, can I give my permit to someone else?
No. Permits are non-transferable. If you are leaving the program and others in your carpool wish to stay in the program, they must apply on their own.
