Group Retrospective Rating Program

Lower Your L&I Costs with WTA’s Retro Program

WTA’s Retrospective Rating (Retro) Program brings motor carriers together to improve workplace safety, manage claims effectively, and reduce overall workers’ compensation costs.

Under the Retro model, member premiums are pooled and evaluated as a group. When the group’s overall claims costs are lower than expected, L&I may issue refunds to participating members. While refunds are never guaranteed, WTA’s Retro Program has a strong history of returning money to members through safer performance and effective claims management.

WTA partners with Integrated Claims Management, a trusted third-party administrator with a proven track record of success. Together, we provide proactive claims oversight, individualized support, and safety guidance that helps members control costs, close claims faster, and strengthen their safety culture.

Through collaboration and accountability, WTA’s Retro Program continues to make Washington’s trucking industry safer—and more cost-effective—for everyone.

Is There a Cost to Join?2025-12-02T16:16:37+00:00

Yes. Enrollment in WTA’s Retro Program costs a percentage of your annual L&I premiums, billed quarterly. Of that amount, a portion is set aside in reserves to help protect the group’s liability exposure. After the third and final Retro adjustment, if the Retro year is positive, a portion of those reserves may be returned to participating members.

Do I Have to Be a WTA Member to Apply?2025-12-02T16:17:06+00:00

Yes. Active membership in the Washington Trucking Associations (WTA) is required for all Retro participants to remain in good standing within the program. However, non-members may apply to the WTA Retro Program first to determine eligibility before joining WTA. Regardless of qualifying status, research shows that companies belonging to their state trucking association have stronger safety outcomes than those that do not. Learn more in the ATRI report Membership Counts: Associations with Safety.
