The government's reminding people drone use is strictly banned over the Manx Grand Prix and Classic TT courses.
It points out violating the rule can result in fines up to £10,000.
Airspace restrictions apply within 1,000 metres of the course during road closures, and within five miles of Douglas during the RAF Typhoon display on Thursday, August 28.
Officials are warning drones endanger riders, disrupt emergency services, and could halt racing if spotted - with only police and authorised media allowed to operate the aircraft.
