See 2018 exemption allowing wheels.
A Tandem Exemption extension was granted in 2016, valid until Sept 30, 2018 and a news item published with a link to the new exemption. It has been made easier to find now and a link is present in the Instructor’s Page, available to USPPA instructors under Schools and Training.
The exemption must be carried when exercising authority as Tandem Instructor.
Thank you instructors for all you do to make this sport safer and more fun.
