Often heard on the CB between Truckers. If a driver has passed them and left a turn signal on, they will call up and tell them they are running out of "Blinker Fluid"
Hey that Bull Hauler that just passed the FreightShaker in the hammer, your gonna run outta Blinker Fluid.

Get the blinker fluid mug.
The liquid in one's vehicle which causes the turn signals to activate. When one's blinker fluid is empty, the result is the inability to use one's turn signals.

Joe: Damn! I almost hit that SUV that just turned into my lane!
Tom: She's just out of blinker fluid.
Joe: Oh, that explains it.
