The tires on your drive-test vehicle must have what minimum tread depth?
-
A.
No specific tread depth applies as long as the tires hold air.
-
B.
Any tire is fine unless it is a donut tire.
-
C.
At least 1/32-inch of uniform tread depth. Correct
The answer is "At least 1/32-inch of uniform tread depth."
The vehicle must have at least 1/32-inch of uniform tread depth to pass the pre-drive inspection. Choice B picks up the donut-tire ban listed one sentence later and treats that single item as the whole tire rule, dropping the separate measured tread requirement.
The traps in the wrong answers
A. No specific tread depth applies as long as the tires hold air.
Skips the 1/32-inch measurement in favor of an air-in-the-tire check. This answer reduces the tire rule to a functional pass, missing that California prints a measured minimum.
B. Any tire is fine unless it is a donut tire.
Names the donut-tire ban but misses the separate 1/32-inch tread requirement listed alongside it. This answer reads the donut prohibition as the whole tire rule instead of one item next to a measured tread standard.
