About This Sign

This advance warning sign tells drivers to prepare for a stop sign that may not be visible until close range.

Where you will see it

You see this sign before a stop sign that may be hidden by a hill, a curve, or trees, so you do not see it until you are close.

What to do

  • Take your foot off the gas and start slowing down.
  • Look ahead for the stop sign and any cross traffic.
  • Be ready to come to a full stop when you reach it.

A common mistake

This sign is not the stop sign itself. Some drivers treat it as the place to stop, but it only warns that a stop is coming further ahead.

What to remember for the test

Remember it is an advance warning, so you slow down but do not stop at this sign. The actual stop happens at the stop sign it warns about.
