GLADSTONE truck drivers have defended their reputation after a video of a truck driving dangerously on the Bruce Hwy emerged online.
Last Sunday Jason Keable filmed his terrifying ordeal with a semi-trailer when he was travelling through Benaraby on the Bruce Hwy.
Mr Keable guessed the truck was travelling in excess of 126km/h when it overtook his car over double white lines.
But Calliope truck owner and driver Viv Hunt has been working in the industry for 33 years, and warned car drivers off judging truck speeds.
"There are very few cars on the road with accurate speedometers," Mr Hunt said.
"So people are thinking they're doing 100km/h and the truck is overtaking, but actually they might be doing 95 or even less."
Mr Hunt said it was possible to override speed limiters, but said random inspections by Highway Patrol were targeting tampering.
Fellow truck driver Terry Finley agreed.
Mr Finley drove B-double trucks between Brisbane and Gladstone for eight years and said he had seen it all.
"People like to say that truck drivers are in the wrong, without any proof," Mr Finley said.
DRW-Wettenhalls, the company of the truck in question, said speed limiters were installed on their fleet.
"This technology allows us to deal with factual evidence, which gives us the opportunity to continually strive to improve our safe driving practices," a spokesman said.
