Should you turn left just because an oncoming car signals right?

No, wait until that vehicle actually begins turning.

  1. No, wait for it to turn ✔
  2. Yes, signals guarantee movement
  3. Yes, if you wave first

Why: A signal may be left on or may refer to a later turn. Wait until the vehicle starts turning before crossing its path.

Huh, didn't know that: Turn signals show intent, but drivers must still confirm the movement is happening.
