Which of the following is one of the four ways the Texas manual says traffic signs help you be a better driver?
-
A.
They mark the boundary between counties
-
B.
They regulate the speed and movement of traffic Correct
-
C.
They flash to signal emergencies ahead
-
D.
They set fines for common traffic violations
The answer is "They regulate the speed and movement of traffic"
The manual lists 'regulate the speed and movement of traffic' as one of the four ways signs help a driver, alongside warning of hazards, guiding to destinations, and informing of local regulations. The trap is 'they set fines': signs do enforce the rule the fine attaches to, and a driver who reads 'regulate' as 'penalize' assumes the sign itself carries the penalty amount when the vehicle code sets that separately.
The traps in the wrong answers
A. They mark the boundary between counties
The manual's four-item list does not name county boundaries as a purpose. Chosen because a driver has seen 'entering county' markers and generalizes that into a core function of all road signs.
C. They flash to signal emergencies ahead
Only signals, not general signs, flash to signal emergencies; the manual's four-item list does not include this. Picked by a driver conflating in-roadway lights and flashing signals with static traffic signs.
D. They set fines for common traffic violations
Fines are set in the vehicle code and by the courts, not by the roadside sign. Comes from reading 'regulate' as 'penalize' and assuming the sign itself carries the penalty amount.
