You must signal before any turn or lane change. a. 5 seconds b. 10 seconds c. 50 ft d. 100 ft

Option D. We must signal 100 ft before any turn or lane change.

Explanation:

We must signal 100 ft before changing in turns or any lanes. Mainly we can use the proper indicator of our car to show which way we are trying to get the turn, so that the vehicles behind can understand.

If anyhow the indicators are not working properly, we should use our hands as indicator and the way of turning.

the correct answer is d
