Question

you are driving on a busy three - lane street. how do you determine youre the necessary 3 ft. away from the edge of your lane?
when the left headlight lines up with the lane boundary
when your left arm lines up with the lane boundary
when the left side mirror lines up with the lane boundary
when the left fender lines up with the lane boundary

Explanation:

To determine if you're 3 ft away from the left edge of your lane while driving, a common visual reference is when the left fender lines up with the lane boundary. This is a standard driving technique where aligning the left fender (the front part of the car near the wheel well) with the lane boundary indicates you are approximately 3 feet away from that edge. The other options (left headlight, left arm, left side mirror) are not standard or accurate references for this specific distance determination.

Answer:

when the left fender lines up with the lane boundary
