A motorist is set to lose his licence after being clocked at 141 km/h on the Princes Highway on Christmas Eve.
Heywood police intercepted the vehicle travelling more than 40 km/h over the speed limit at Drumborg.
When asked why he was driving so fast the driver said it was "a long straight bit of road and there was no traffic".
The motorist was fined $682 and his licence will be suspended for six months.
