The Isle of Man's Civil Aviation Administration has banned drones from being flown during TT races, and says practice sessions and races could be halted if they are spotted.
Drone operators will face large fines if they flout the 'no-fly zone', which will be imposed across the island's famous mountain course during this year's TT races between May 26 and June 8.
Drone operation will be banned within 1000 metres of the route, whenever the roads are closed for the racing.
Only authorised drones, such as the one operated in support of the police, will be allowed to enter this airspace.
"Drones can pose a serious distraction to riders, and race marshals are informed to immediately report any drones to race control and the police which may result in the practice or race being halted," said Civil Aviation Administration director Colin Gill.
Breaching the rules could incur a fine of £2500.
"The airspace above the TT course can get busy with emergency and filming activity by helicopters before, during and after racing or practising takes place," added Gill.
"The Southern 100 course is also located within three miles distance of Isle of Man Airport within which drones should not be flown due to the dangers they could pose to an aircraft taking off or landing at the airport."
