Passing target: 80% (24/30)
You drive on a city street and plan to turn right into a driveway ahead. How long must your turn signal be on before you turn?
A heads right along a two-way city street toward a driveway on its right. No signaling distance or answer route is marked in the question image.
Correct answer: For at least the last 100 feet before the turn, without a break.
Why
A signal is useful only when others see it in time to react, so the law sets a minimum distance. Turn it on early enough to cover the last 100 feet or more, but not so early that drivers think you will turn at an earlier street or driveway. After the turn, make sure that the signal has turned off so that it does not confuse other drivers.
