Queensland drivers who use their phones behind the wheel will be hit with a $1000 on-the-spot fine from Saturday.

Drivers caught twice risk losing their licence and facing double demerit points, Transport Minister Mark Bailey said.

Queensland will trial cameras already in use in NSW that are specifically designed to detect mobile phone use on the roads.

"Thirty-three lives were lost to distraction last year, 1300 crashes, and we believe that is an under reporting," he said.

"Research shows driving distracted by your mobile phone or anything else is the equivalent of driving with 0.07 to 0.1 blood alcohol in your system.
