Police are asking fans to stop littering around the TT course.
Officers say they've received reports of incidents where bottles and cans have rolled into the road, endangering riders.
This year's already seen one competitor have a close shave after they went over a bottle which had rolled onto the course.
While marshals check for items in the road, they can't do so once racing starts - officers are asking spectators to keep belongings and litter with you and take it away when you leave.
