On the [[Snaefell mountain road]] section from Ramsey to Douglas, the official vehicle displays the notice ''Roads Open One Way.''

Originally introduced in 1935, there are eight machines positioned around the course to provide a rapid response to any incidents. Selected riders have previous race experience and are first-aid trained, with machines carrying medical equipment that can assist in managing a casualty. They also have other duties such as course inspection, observation of machines on the course for visible faults, and review and report any course incidents.<ref>[https://www.iomtt.com/news/2013/05/29/yamaha-keep-travelling-marshals-on-road-and-track Yamaha keep travelling marshals on Road and Track] iomtt.com, 29 May 2013.
