- MUTCD W14-1
Shape and background first
Federal designation W14-1 in the MUTCD, the national standard every state signs to. Posted at the entrance to the street itself, before you commit, rather than partway down it, so you get the warning while there is still room to choose a different route.

What the test wants you to know
The mistake people make
A dead end still allows turns onto side streets along the way, it is only the road itself that stops, which is what separates it from a full cul de sac with no side access at all. Some states use a T shaped symbol version of this sign instead of the plain text plate, so tests may show either.
The sign people confuse it with
Dead End gets mixed up with No Outlet more than any other pairing in this category. Put them side by side and the difference is obvious, which is exactly why it is worth doing once rather than meeting them cold in the exam.
Dead End
The road ahead terminates with no through connection.
No Outlet
The street or network of streets ahead has no through connection to another road, even though it may branch and wind for some distance first.
