Should drivers be required to complete safety education before navigating dangerous mountain roads?
Wyoming Department of Transportation crews began installing updated safety signage on Teton Pass following three deaths and multiple injuries during the summer of 2026. The new signs are designed to reach all motorists rather than just commercial truck operators.
Why it matters
The safety measures respond to a surge in accidents on the steep mountain terrain of Teton Pass. Officials implemented these changes to better inform drivers of critical hazards like sharp curves and gear requirements before they navigate the challenging route.
New signs now warn all motorists about steep grades and low gear requirements, replacing previous warnings focused only on truckers. A new mandate applies to any vehicle over 10,000 pounds.

Timeline
Summer 2026: Three deaths and multiple injuries occurred on Teton Pass.

Roadmap
The new safety requirements represent a shift toward mandatory driver accountability on hazardous public roads. This evolution moves state policy away from passive signage toward active driver certification programs to mitigate risks in mountainous corridors.
Motorists driving vehicles over 10,000 pounds face mandatory certification requirements to use the pass legally. All drivers should prepare for stricter parking enforcement and mandatory brake checks when navigating Highway 22.
The takeaway
Drivers should ensure their vehicle is properly maintained and their gear usage is correct before tackling steep mountain grades. Adhering to the new signage and completing the Safe Pass program is essential for maintaining safety on Teton Pass.
What happens next
Drivers of vehicles weighing over 10,000 pounds must complete the Safe Pass education program starting October 1, 2026.
