The default speed limit in Illinois city and town areas is:
-
A.
25 mph
-
B.
35 mph
-
C.
20 mph
-
D.
30 mph Correct
The answer is "30 mph"
City and town areas default to 30 mph unless a posted sign changes it. Drivers who bring a 25 mph residential-street habit over from another state pick A; Illinois sets the general city and town figure one step higher.
The traps in the wrong answers
A. 25 mph
Illinois's general city or town default is 30 mph, not 25 mph. This answer reaches for the 25 mph business-district figure common in some other states, rather than the Illinois city and town row the manual prints.
B. 35 mph
Illinois's general city or town default is 30 mph, not 35 mph. This answer generalizes the 35 mph posted on wider main roads to every city street, in place of the general city and town row the manual prints.
C. 20 mph
The 20 mph figure is Illinois's school-zone limit, and it applies only on school days between 6:30 a.m. and 4 p.m. when children are present and signs are posted, not the general city or town default. This answer skims the school-zone bullet for the number and misses the parenthetical that scopes it to school days, school hours, and children present.
