One-way system and road closures not indicated
Police are advising TT visitors to switch off their Sat Navs when on the Island.
Officers say bikers and motorists using GPS are being mis-guided when they get to Creg ny Baa.
The temporary road closures and one way system over the mountain are not picked up by Sat Navs - and road users should ignore them and obey the road signage in place.
