Are we allowed to hang a team flag on the loading station or near the driver’s station on the field while competing?
Where the human player is? No. Check out H1
Couldn’t it work since it says “reasonable decorative items” or would that not include a flag?
No, “reasonable decorative items” is item C, which is in the range B-G. As such, they are not allowed to attach to the field, arena, or operator console. This pretty much means that it would have to simply be standing in place, or held by a member of the drive team.
