Vehicles in Illinois must have two red taillights visible from behind for at least what distance?
-
A.
100 feet
-
B.
200 feet
-
C.
300 feet
-
D.
500 feet Correct
The answer is "500 feet"
Illinois requires two red taillights that are visible for 500 feet from behind. A learner who picks 200 feet is pulling the horn-audibility or rearview-mirror figure from the same equipment list and applying it to the taillight rule.
The traps in the wrong answers
A. 100 feet
This answer reaches for the low end of the moped taillight visibility range instead of the passenger-car rule. It comes from picturing a following distance of one or two car lengths rather than an open-road sightline.
B. 200 feet
This answer grabs the 200-foot figure that governs the horn and rearview mirror in the same equipment list. It applies the 200-foot horn-audibility or rearview-mirror figure printed nearby to the taillight requirement.
C. 300 feet
This answer borrows the turn-signal visibility distance listed just below the taillight entry. It carries over the 300-foot turn-signal visibility rule from the next entry in the same list.
