Safer, more efficient left turns

A flashing yellow arrow signal is placed over the left‑turn lane at an intersection. It provides a safer and more efficient left‑turn option for motorists and will replace the flashing red left‑turn signals commonly used throughout Michigan.

Remember: A flashing yellow arrow means turn with caution.

  • A national study showed that drivers made fewer mistakes with flashing yellow arrow signals compared to traditional left‑turn signals.

  • Flashing yellow arrows give motorists more opportunities to turn left turn, reduce delays, keep traffic moving and provide flexibility for traffic management.

  • Motorists will see the same left‑turn signal system in every state.

Design and function

The flashing yellow arrow provides a more direct message to motorists and helps reduce confusion.

  • When illuminated, the flashing yellow arrow indicates that motorists may turn left with caution after yielding to oncoming traffic and pedestrians.
  • After flashing, it changes to a steady yellow or green arrow. A steady yellow arrow should be treated like any standard yellow signal, meaning drivers should prepare to stop or safely complete the turn.
  • A green arrow indicates that oncoming traffic has stopped and it is safe to turn left.
