What to Do
Begin slowing and prepare to stop at the actual stop line or junction.
A Detail to Remember
The red octagon inside a yellow diamond is advance warning; it is not the place where the stop must necessarily occur.
Understanding Warning Signs
Yellow warning signs ask you to anticipate a condition ahead. Read any distance or speed plaque with the main symbol, then adjust to what you can actually see on the road.
