The drink driver was pulled over in Burnie with a blood alcohol level of 0.171, more than three times the limit. Officers discovered the motorist was disqualified for  a prior drink-driving offence. 

The P-plater motorcyclist was caught doing 140 km/h on the 100 km/h Frankford Highway.

As a provisional driver the rider is limited to a maximum speed of 80 km/h. 

``These two drivers were crashes waiting to happen which have been prevented by police enforcement over this period,'' Northern Roads and Public Order Safety Inspector  Darren Hopkins of Tasmania Police said today. 

Tasmania Police's annual Christmas road safety campaign Operation Crossroads has busted 23 drink-drivers since Monday. 

Three motorists have had their vehicles clamped in that time.

Police have issued 302 traffic fines, an increase of 15 per cent on last year, while 196 speeding offences have been detected. 

Officers have conducted more than 6500 RBTs,  an increase of 34 per cent compared to last year's operation. Out of 11 drug tests, five motorists have tested positive. 

Nearly 50 drivers have been caught committing licence offences. 

Fortunately there have been no fatalities on Tasmania's roads during the operation. 

Crossroads will finish at midnight on January 4.
