When does the passing restriction created by this Do Not Pass sign end?
-
A.
When a Pass With Care sign or permissive pavement markings appear ahead. Correct
-
B.
After you have driven 500 feet past the sign.
-
C.
When you reach the next intersection or cross street.
-
D.
When oncoming traffic clears and the road ahead looks empty.
The answer is "When a Pass With Care sign or permissive pavement markings appear ahead."
The restriction runs from the sign forward and is lifted only by a Pass With Care sign or by permissive pavement markings. The tempting wrong choice is the one that lets a clear stretch of road end the restriction; a driver used to judging passing by sight distance reads Do Not Pass as advice to weigh against conditions, when it is a rule that stays in force until a later sign or marking cancels it.
The traps in the wrong answers
B. After you have driven 500 feet past the sign.
This answer invents a fixed distance that the entry does not provide; the restriction stays in force until another sign or marking cancels it.
C. When you reach the next intersection or cross street.
Intersections do not lift a Do Not Pass restriction; only a Pass With Care sign or permissive markings do. This answer carries over the way lane-use restrictions such as turn-only lanes end at the next intersection and applies that habit to a passing rule.
D. When oncoming traffic clears and the road ahead looks empty.
The sign overrides the driver's own read of the road; the restriction holds even when a gap in oncoming traffic looks inviting. This answer confuses the sign with a yellow warning plate that leaves the call to the driver, when this white regulatory sign binds regardless of the road ahead.
