What sign is displayed on a pilot car used to lead traffic through a one-lane section?
B. PILOT CAR FOLLOW ME
The pilot vehicle carries a PILOT CAR FOLLOW ME sign on its rear so the queue knows to follow it. The other signs are roadside signs, not the sign mounted on the pilot car.
Reference: MUTCD Part 6, one-lane, two-way traffic control (2009 Edition Sections 6C.10 to 6C.15)
Which background color may be used on warning signs set up for a traffic incident such as a crash scene?
B. Fluorescent pink
Signs in a traffic incident management area may use a fluorescent pink background with black legend, which sets them apart from planned road work. The other colors have no such use on warning signs.
Reference: MUTCD Part 6, traffic incident management areas (2009 Edition Section 6I.01)
How should the lights at a night flagger station or work area be aimed?
C. So they light the area without glaring into drivers' eyes
Floodlights must not produce disabling glare for approaching road users, flaggers or workers. Lights aimed at oncoming traffic blind drivers just as they reach the flagger.
Reference: MUTCD Part 6, flagger stations (2009 Edition Section 6E.08) and lighting devices (Section 6F.82)
