If you cannot see both side mirrors of a large vehicle ahead, what does that indicate?
Blue A follows a white tractor-trailer on a highway. The Q card gives the normal clear-road conditions; no mirror-detail hint or safe-gap marking appears.
Correct answer: You may be in its rear blind area and should increase the gap
Why
Stay far enough behind a large vehicle to keep useful sight lines to its side mirrors and see more of the road. Seeing a mirror is a positioning aid, not a guarantee that its driver has noticed you.
