Officers have a 'zero tolerance' policy
The Isle of Man Constabulary says policing Manx Grand Prix and TT can be 'frustrating' when people ignore the rules.
Every year officers have to arrest people who are illegally flying drones, entering closed roads or taking pedal bikes on the Mountain Road.
Some of the offences can carry hefty fines or even prison sentences.
This year, a Merseyside man was caught flying a drone near the Creg Ny Baa just two hours into the first road closure on Sunday 17 August.
He was fined £750.
In another incident, a local man crossed the course at St Ninian's traffic lights - during a qualifying session on Tuesday 19 August.
Footage which circulated widely online in the aftermath showed a bike flying through the area just seconds after he reached the EVF petrol station on the other side.
He was later sentenced to 16 weeks’ custody for crossing the road and 8 weeks for provoking behaviour during an appearance at Douglas Courthouse, according to Isle of Man Today.
