A Texas school zone posts a regulatory sign showing a cell phone with a red slash across it. According to the manual, what does the sign prohibit inside the zone?
-
A.
Talking on a cell phone during posted school hours only.
-
B.
Answering calls without pulling to the side of the road.
-
C.
Using a wireless communication device. Correct
-
D.
Using a hand-held cell phone unless it is hands-free.
The answer is "Using a wireless communication device."
The Texas school-zone sign prohibits the use of a wireless communication device inside the zone. The hands-free carve-out in D comes from the general Texas rule that lets an adult use a hands-free device on the road, and drivers carry that exception into a zone where the manual states none.
The traps in the wrong answers
A. Talking on a cell phone during posted school hours only.
The manual ties the device ban to the sign itself, not to the flashing-yellow-light schedule that sets the school-zone speed limit. This answer confuses the reduced school-zone speed limit, which is in effect only while the yellow light flashes, with the separate wireless-device ban.
B. Answering calls without pulling to the side of the road.
The sign is not telling drivers where to take a call; it prohibits using the device while driving in the school zone. This answer applies the general safe-driving habit of pulling over to take a call to a sign that bans the use itself, not the location of it.
D. Using a hand-held cell phone unless it is hands-free.
The manual states the sign prohibits the use of a wireless communication device, which is broader than a hand-held cell phone. This answer carries over the general Texas rule that lets adult drivers use a hands-free device on the road and applies it inside the school zone.
