The Queensland Police Service is committed to reducing the number of lives lost on our roads. However, enforcement alone cannot stop all dangerous driving behaviours.
Every choice you make behind the wheel, matters. Driving under the influence, speeding, driving distracted or while fatigued, or not wearing a seatbelt puts your life – and the lives of others – at serious risk. These dangerous behaviours will not be tolerated.
Queenslanders can expect police – anywhere, anytime.
Road safety starts with you.
