What the Stop Ahead sign means

This yellow diamond pictures a red stop-sign symbol, warning that a stop sign is coming up — often around a curve, over a hill, or in a spot where you could not otherwise see it in time. Begin slowing so you can make a full, controlled stop at the upcoming sign. It gives you advance notice on higher-speed roads or where the stop is unexpected. Do not wait until the actual stop sign comes into view; start easing off the accelerator the moment you see this warning.

What to do when you see it

Start slowing now so you can make a smooth, complete stop at the stop sign ahead.
