Uncommon

Steep Grade

What It Means

A yellow diamond showing a truck angled downhill, usually paired with a percentage (like 7% or 8%) indicating how steep the descent ahead is.

How Rare Is It on Road Sign Hunt?

Uncommon. You'll find these, but you have to keep watching.

Spotting Tip

Mountain passes and canyon roads are the reliable place to find these — the steeper the terrain on your route, the more of these you'll pass.

Fun Fact

The percentage isn't the angle of the slope — it's the ratio of vertical drop to horizontal distance, so an “8% grade” means the road drops 8 feet for every 100 feet traveled.
