Rare

Chain Up Area

What It Means

A white regulatory sign with a tire chain icon, marking a pullout where drivers are required or permitted to install snow chains before continuing up a mountain grade.

How Rare Is It on Road Sign Hunt?

Rare. Worth a detour through the right kind of road.

Spotting Tip

Mountain passes in snow-prone regions — the Sierra Nevada, Rockies, and Cascades are classic examples — post these ahead of steep winter grades.

Fun Fact

On some mountain passes, chain requirements can be enforced by law during storms, and skipping a mandatory chain-up area can result in a real ticket, not just a suggestion.
