생김새
A yellow diamond-shaped warning sign with a black symbol or the legend LOOSE GRAVEL showing stones kicking up from a wheel.
언제 보게 되나요
On roads recently surfaced with chip seal or where gravel has spread onto the pavement, common on rural and freshly maintained roads.
무엇을 해야 하나요
Slow down to keep control; loose gravel reduces traction and can be thrown by tires, so leave extra distance from vehicles ahead.
