MDOT explains the new flashing yellow left-turn signal

To help motorists understand the new flashing yellow left-turn signal, the Michigan Department of Transportation (MDOT) has posted an animated video on MDOT's YouTube channel: www.youtube.com/MichiganDOT.

For years, Michigan drivers have been making left turns from lanes where the signal light is flashing red. But soon there will be a new traffic signal that offers a safer, more efficient way for traffic to turn left at busy intersections.

The signals are being introduced nationwide and ultimately will be required at all intersections where there is a separate left-turn arrow signal. This change is the result of a national study conducted by the Federal Highway Administration, which demonstrated that the new signal helps prevent crashes, moves more traffic through an intersection, and provides more flexibility in traffic management.

The flashing yellow arrow is part of a four-arrow light. What do you do when you see the flashing yellow? It's simple: be cautious, and after yielding to oncoming traffic and pedestrians, make your left turn.

After it flashes, the flashing yellow then turns to a solid yellow left-turn arrow, which means prepare to stop.

When the light turns to a solid green arrow, turn left. Oncoming traffic must stop.

Just remember: a flashing yellow signal means turn with caution. More information, including a link to download a brochure and a demonstration of how the signal works, is available at www.michigan.gov/flashingyellowarrow.
