As part of a covert operation, Latrobe Traffic Management Unit police position themselves, and a radar, in bushland along roads notorious for speeding motorcyclists.

Once an offence is detected, the camouflaged members radio a police unit stationed further down the road to intercept the offender.

Officer in charge Sergeant Clint Wilson said 24 per cent of serious injury collisions in the area involved motorcyclists and enforcement methods using marked cars had not been as successful as hoped.

``It's (the operation) labour intensive but it's a serious problem that we need to address, we've gone to this length to ensure that we can make our roads safer,'' Sgt Wilson said.

``Riders know where they can ride and get away with speeding.

``In this particular case, the motorcyclists are riding in areas surrounded by bushland and on bends and in locations that are dangerous to ride, and for us to blend in to the environment there, we need to be in a camouflage uniform so as not to stand out.''

The operation is based on a successful one conducted in the Yarra Ranges, where members contend with winding, narrow roads that prove difficult to police.

``We want the message to get across, particularly to riders that come out on weekends... we encourage them to ride in the Gippsland area, there's a lot to offer for weekend rides but, if you do it, stick within the law so that you remain safe,'' he said.

The operation targets motorcycles but will also nab vehicles for the same offences.

The unit is calling on the public to report areas frequented by speeding riders.
