The Queensland Government is launching a world-first road safety campaign encouraging drivers to "drive smarter, not faster" ahead of the Easter long weekend.

The Palaszczuk Government worked with behavioural neuroscientists to devise eight simple exercises to help Queenslanders stop speeding or being distracted and focus on their driving.

Transport and Main Roads Minister Mark Bailey says he "encourage[s] all Queenslanders to visit the Street Smarts website and try the experiments to see which ones work [for them]."

Last Easter long weekend, four people were killed and 102 were hospitalised as a result of crashes on Queensland roads.
