You should only use your high-beam highlights when you are more than feet behind another vehicle you are following.
a. 100
b. 200
c. 300
d. 400

Option C is the answer.

Explanation:

It is necessary to use high-beam highlights anytime you cannot see clearly enough to drive safely. It is very important to learn to use them because even though they can be very helpful they are also able to endanger other drivers if they aren't used carefully. When you are 300 feet behind another vehicle you are following it is safe to use them; for closer distances, they mustn't be used.
