Side road sign
A yellow diamond with a straight line and a shorter one joining from one side. It warns of a side road entering ahead, from the side shown.
How to read it
It is one of the MUTCD's intersection warning signs, used ahead of an intersection to show that it is there and that traffic may turn or enter. The side the short line joins shows which side the other road comes in from.
Rules vary by state and country. This explains the sign's standard meaning in the U.S. Manual on Uniform Traffic Control Devices; it isn't legal advice.
