During the 2021-2022 school year, through a grant from Ford Driving Skills for Life and GHSA, the Montana Department of Transportation partnered with six local FCCLA chapters to create, implement and distribute teen traffic safety messaging in their communities with a focus on speeding.
In 2018, Montana’s State Highway Traffic Safety Office (SHTSS) was awarded grants by both Ford Driving Skills for Life and The National Road Safety Foundation, Inc.'s partnerships with GHSA. With these funds, SHTSS launched a statewide contest between Family, Career, and Community Leaders of America (FCCLA) chapters to create peer-to-peer teen safe driving campaigns, with an emphasis on drowsy driving.

WASHINGTON, D.C. – The Governors Highway Safety Association (GHSA) and Ford Driving Skills for Life (Ford DSFL) have awarded State Highway Safety Offices in five states funding to support teen safe driving programs.
As a recipient of one of GHSA and the Foundation for Advancing Alcohol Responsibility's (Responsibility.org) grants to combat drug-impaired driving, the Montana State Highway Traffic Safety Section (SHTSS) was able to train more than a dozen new Drug Recognition Experts (DREs) in 2017.
