How many seconds before turning should you signal?

1 second
3 seconds
5 seconds
10 seconds

The correct answer is: 3 seconds

You should signal approximately 3 seconds before making a turn. This allows other drivers and pedestrians enough time to react to your intention to turn. Option A is incorrect because 1 second is too short of a notice and may not be visible to others. Option C is incorrect because signaling 5 seconds before turning may cause confusion for other drivers as they may think you are merging into a different lane. Option D is incorrect because signaling 10 seconds before turning is too far in advance and may not accurately represent your actual intention to turn.
