TT marshals medical assistance collection
Race marshals around the TT course are estimated to have raised thousands of pounds for a fund which pays for road race medical assistance.
The Rob Vine Fund, named after a TT competitor from Kent who died in 1985, provides equipment and training for TT doctors, paramedics and marshals.
Marshals reported that they had raised up to £400 each a day from spectators.
A marshal spokesman said people understood the importance of early medical assistance at crashes.
James Palmer, a marshal who has raised more than £2,000 so far, said that spectators had been generous in their contributions to his colleagues' new yellow collection buckets.
He said: "Without the first aid equipment being in the helicopters for instance they wouldn't be able to operate efficiently."
