Under Florida equipment rules, a muffler is not permitted if it can be heard from more than what distance?
-
A.
50 feet Correct
-
B.
100 feet
-
C.
200 feet
-
D.
500 feet
The answer is "50 feet"
The Equipment NOT Permitted list caps a muffler at 50 feet of audibility. Choice C, 200 feet, is the horn's audibility figure from the required-equipment table printed on the same page, and drivers who conflate the two audibility rules pick it.
The traps in the wrong answers
B. 100 feet
The Equipment NOT Permitted list sets the muffler cap at 50 feet, not 100. Rounds the 50-foot cap up to a familiar hundred-foot threshold carried over from municipal noise ordinances.
C. 200 feet
Two hundred feet is the horn-audibility requirement in the required-equipment table, not the muffler cap. Swaps the horn's 200-foot audibility figure from the required-equipment table for the muffler's 50-foot cap because both rules describe how far a sound must carry.
D. 500 feet
Five hundred feet is the directional-signal visibility distance in the required-equipment table, unrelated to the muffler rule. Grabs the directional-signal visibility figure printed on the same page, on the assumption that noise limits apply at long range.
