A TOOWOOMBA truck driver on a campaign to expose reckless motorists has captured another shocking moment on our roads.

Stuart Masters released dash cam footage earlier this year that captured the moment a distracted driver smashed into his truck at high-speed.

His latest dash cam footage captures a high-risk takeover on an unidentified Darling Downs road.

A vehicle overtakes Mr Masters and only narrowly avoids colliding head-on with an oncoming vehicle.

The close call does nothing to deter the driver who seconds later overtakes another vehicle at high-speed.

Mr Masters has pleaded with motorists to remain alert and "think".
