According to the Texas manual, what is the minimum distance at which a car's horn must be audible?
-
A.
500 feet
-
B.
200 feet Correct
-
C.
1,000 feet
-
D.
100 feet
The answer is "200 feet"
The manual requires a horn to be heard at 200 feet. The pull toward C comes from carrying over the 1,000-foot visibility trigger that decides when headlights must be turned on.
The traps in the wrong answers
A. 500 feet
The horn rule is 200 feet; 500 feet is used for low-beam switching. This answer swaps in the 500-foot distance that governs when to dim to low beams near an oncoming vehicle.
C. 1,000 feet
Horns must be heard at 200 feet, not 1,000. This answer borrows the 1,000-foot visibility trigger that decides when headlights must be turned on.
D. 100 feet
The manual requires horns to be heard at 200 feet, not 100. This answer halves the standard from a habit of underestimating how far sound must carry.
