路面碎石标志
MUTCD W8-7
前方路面有松散碎石,请减速。
标志外观
A yellow diamond-shaped warning sign with a black symbol or the legend LOOSE GRAVEL showing stones kicking up from a wheel.
什么时候会见到
On roads recently surfaced with chip seal or where gravel has spread onto the pavement, common on rural and freshly maintained roads.
该怎么做
Slow down to keep control; loose gravel reduces traction and can be thrown by tires, so leave extra distance from vehicles ahead.
