A Restricted Lane Ahead regulatory sign is posted on a multi-lane highway. What does it mean?
-
A.
The right lane is closing ahead and traffic must merge left.
-
B.
A lane is reserved for certain vehicles, such as buses or carpools. Correct
-
C.
All lanes are open only to vehicles carrying a special permit.
-
D.
The lane ahead is closed for maintenance until further notice.
The answer is "A lane is reserved for certain vehicles, such as buses or carpools."
A Restricted Lane Ahead sign flags a lane held aside for specific vehicles, such as buses or carpools. Drivers who confuse it with the yellow Reduction of Lanes warning pick the closing-lane choice, mistaking a regulatory lane-use rule for the warning that a lane is ending.
The traps in the wrong answers
A. The right lane is closing ahead and traffic must merge left.
The yellow Reduction of Lanes warning covers a closing lane; Restricted Lane Ahead is a use rule, not an ending. This answer confuses the regulatory sign with the yellow Reduction of Lanes warning that announces a merge.
C. All lanes are open only to vehicles carrying a special permit.
The restriction applies to one lane and to a category of vehicles, not to every lane on the road. This answer extends the disabled-permit parking rule to a lane that never required one.
D. The lane ahead is closed for maintenance until further notice.
A lane closed for maintenance would be marked with orange work-zone signs, not this regulatory sign. This answer reads restricted as closed, borrowing the orange work-zone framing.
