T-intersection sign
A yellow diamond with a T shape. It warns that the road ends ahead at an intersection, where traffic turns left or right.
How to read it
It is one of the MUTCD's intersection warning signs. Pennsylvania's manual explains what the intersection signs are for: they show in advance how the roads join, so drivers know when their road does not continue straight through. At the far side of a T-intersection, a Two-Direction Large Arrow sign can point both ways.
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.
