Cattle Crossing Sign
MUTCD W11-4
Cattle or other livestock may be crossing or on the road ahead, often near farms or open range; slow down and be ready to stop.
What it looks like
A yellow diamond warning sign with a black side-view silhouette of a cow.
When you'll see it
On rural highways and open-range areas near farms and ranches where cattle or other livestock may wander onto or cross the road.
What to do
Slow down and be ready to stop; animals can be unpredictable, so give them room and never try to drive around a herd that is on the road.
