An Oregon lane is signed "HOV 2+" with a white diamond painted on the pavement. Who may use this lane during the posted hours?
-
A.
Vehicles carrying two or more persons. Correct
-
B.
Any vehicle, at any time.
-
C.
Only buses and emergency vehicles.
-
D.
Only vehicles with a special HOV permit.
The answer is "Vehicles carrying two or more persons."
An HOV 2+ lane is reserved for vehicles carrying at least two or more persons, as noted on the sign. The white diamond painted on the lane is the visual marker. HOV restrictions apply during the posted hours shown on the sign (for example, 6AM-9AM Monday-Friday). A driver alone in the vehicle does not meet the posted occupancy and may not use the lane during the restricted hours.
The traps in the wrong answers
B. Any vehicle, at any time.
HOV lanes are restricted to qualifying multi-occupant vehicles during posted hours; they are not open to all traffic. Misreading: Ignores the manual's occupancy requirement and treats the HOV lane as a general-purpose lane.
C. Only buses and emergency vehicles.
HOV access is occupancy-based, not vehicle-class-based. Any vehicle meeting the posted occupancy may use the lane. Misreading: Confuses HOV with Transit Only lanes; the manual ties HOV access to occupancy, not vehicle class.
D. Only vehicles with a special HOV permit.
The manual does not require a permit; access is based solely on the number of persons in the vehicle. Misreading: Treats HOV access as permit-based; the manual conditions access on posted occupancy, not a permit.
