My mom was driving,when she was going to take the next left,she used her indicator to indicate that. But when she was turning,a car speeded past was while she was turning.(in the direction we were turning.) So she said:
Hey! I used the indicator to indicate I was turning left.
I gave an indicator to indicate that I was turning left.
What will be a natural way to express this idea? I don't know how this sentence can be spoken naturally in this context....
P.S. She's talking to the driver.
