Ban in place
Fans are being urged not to use drones during Southern 100 races and practice sessions.
Like in the TT, small personal aircraft are banned in the vicinity of closed roads for safety reasons.
The Billown Circuit is also close to Ronaldsway Airport, meaning drones should not be used anyway.
A number of drone incidents were reported during TT, with police promising to prosecute those who broke the rules.
The first practice session for the Southern 100 takes place on Monday evening.
