On a two-lane undivided highway in California, what is the maximum speed limit unless otherwise posted?
-
A.
65 mph
-
B.
55 mph Correct
-
C.
45 mph
The answer is "55 mph"
On a two-lane undivided highway, the manual sets 55 mph as the maximum unless a sign posts something different. The 65 mph choice comes from the general highway figure printed in the same paragraph one sentence earlier; a driver who anchors on the higher number and skips the two-lane exception picks it.
The traps in the wrong answers
A. 65 mph
This is the general California highway maximum, not the two-lane figure. This answer anchors on the higher general-highway number and skips the two-lane exception printed one sentence later.
C. 45 mph
Below any highway maximum the manual states. This answer rounds down under the assumption a narrow two-lane road must be treated like a residential street.
