道路变窄标志
MUTCD W5-1
前方道路两侧变窄,空间减少;请减速并注意对向来车。
标志外观
A yellow diamond warning sign whose black symbol shows the two edges of the road angling inward so the roadway gets narrower toward the top.
什么时候会见到
Ahead of stretches where both edges of the pavement close in — older rural roads, approaches to bridges, or where a wide road drops to a narrower width.
该怎么做
Slow down, keep to the center of your lane, and watch for oncoming vehicles, since there is less room for two-way traffic through the narrow section.
