In 2026, we released two new versions of CARS: CARS-SC and CARS Connect. Both represent a streamlined version of CARS that is faster to administer but retains its validity for mental health screening. Both have impaired driving modules that are only activated if a screening is being completed for an impaired driving program, so can be used by a variety of programs. CARS Connect is a cloud-based version of CARS and can be accessed by registering for an account at carstrainingcenter.org/cars-connect. CARS-SC can be installed the same way as past versions of CARS, and can be downloaded below. Different versions of CARS do not interface with each other, so it is important to choose one to work with. Unsure which one to use? Check out our comparison of CARS versions.
