On a Nevada freeway, a dotted white line beside your lane may indicate what?
-
A.
A broken white lane line where passing between lanes is permitted
-
B.
A high-occupancy vehicle lane you may enter any time
-
C.
A shoulder that is closed to all vehicles
-
D.
An exit-only lane on the freeway Correct
The answer is "An exit-only lane on the freeway"
Dotted white lines are shorter and spaced closer than the more familiar broken white lane lines. On a freeway they typically mark an exit-only lane: the lane you are in is about to leave the freeway. They can also extend a lane line through an intersection.
The traps in the wrong answers
A. A broken white lane line where passing between lanes is permitted
The manual treats these as two different markings: broken white lines mark ordinary same-direction travel lanes where passing is allowed when safe, while dotted white lines (shorter and more closely spaced) mark exit-only lanes on a freeway. This answer hears 'dotted' as a synonym for 'broken' and defaults to the familiar same-direction lane-change stripe most drivers see every day.
B. A high-occupancy vehicle lane you may enter any time
HOV lane access is controlled by broken or double solid white lines, not by a dotted white lane line. This answer reaches for the HOV rule because carpool-lane markings are the one 'special white line' most drivers can name, so any unfamiliar freeway line defaults to that answer.
C. A shoulder that is closed to all vehicles
A shoulder edge is marked by a solid white line, not a dotted lane line. This answer reads any interrupted white line as a sign the adjacent surface has been taken out of service, borrowing the intuition from lane-closure markings and pasting it onto the shoulder.
