Which statement correctly describes where riders are allowed to stand on a bus with a standee line?

49 CFR 383.117(a)(6) (operating practices not otherwise specified); AAMVA CDL Manual Section 4.2.3 "Standee Line," p. 4-2

Keeping standing riders out of the area near the driver protects the driver's sightlines and reaction space, which matters every time the bus brakes or turns. This question checks that applicants understand the actual boundary the rule draws, not just that a boundary exists.
