Question

when should you signal?
50 feet, or 2 blinks, before your turn
500 feet, or 5 seconds, before your turn
100 feet, or 3 seconds, before your turn

Explanation:

In driving rules, the correct practice is to signal 100 feet (or about 3 seconds) before making a turn to give other drivers adequate notice. The first option (50 feet/2 blinks) is too close, and the second (500 feet/5 seconds) is too far in typical driving scenarios.

Answer:

100 feet, or 3 seconds, before your turn
