A HEAVY VEHICLE has been clocked by NSW Traffic and Highway Patrol travelling well over the speed limit. 

The vehicle was stopped by police on the Hume Highway, Pheasants Nest early Thursday morning after it was detected doing 144km/h in a 110km/h zone.  

The Victorian-registered prime mover, which was hauling three excavators, is restricted to a maximum speed of 100km/h.  

Assistant Commissioner Michael Corboy of the state's Traffic & Highway Patrol Command said the speed of that truck was among the fastest on record.  

"To have such a heavy vehicle, laden with further heavy machinery, hurtling down the highway at that speed, is a disaster waiting to happen.  

"Officers will always be on the lookout for irresponsible driving behaviour which puts innocent road users at risk," Assistant Commissioner Corboy said.  

The driver of the vehicle was spoken to and a mechanical and electronic examination of the truck was conducted. The truck was found to be in breach of a number of speed limit restrictions as well as oil leaks.  

A major grounded defect notice was issued to the driver, who also received a fine of $1,364 and five demerit points for Class C heavy vehicle exceed speed limit over 30km/h and $2,238 for vehicle not speed limiter compliant when driven on road.
