How states handle it
Some states pair the symbol with a plaque naming the charging network or connector type, while others post it as a plain, unlabeled symbol.
What the test wants you to know
The mistake people make
The plug symbol tells you a charger exists at that exit and nothing more, which matters far more here than it does at a fuel pump: connector type, network membership and whether the unit is fast or slow all sit outside anything the sign can say. Treat it as a prompt to check your own charging app before committing to the exit, because a blue service sign has never promised a working or compatible connection.
