US Road Signs Road Markings

A city street lane is painted solid red across its full width and posted as a bus and transit-only lane. What does this require of you in a private car?

Wide horizontal band of solid red pavement bordered by thin white stripes on top and bottom, on a dark roadway.
  1. A.
    Stay out of the lane except for a permitted right turn or to enter or leave a driveway. Correct
  2. B.
    Use the lane whenever you're carrying two or more passengers as a high-occupancy vehicle.
  3. C.
    Use the lane during off-peak hours when transit service is running lightly.
  4. D.
    Treat the red pavement as a warning of construction or roadwork ahead.
The Why

The answer is "Stay out of the lane except for a permitted right turn or to enter or leave a driveway."

A red-colored lane is reserved for buses and other authorized transit vehicles, and a private driver stays out except for the brief moment needed to make a permitted right turn or to enter or leave a driveway. What counts as permitted is set by the regulatory signs at the lane and by any dotted or broken section of the red pavement; you cross only where those mark the entry as allowed, not on a private judgment about traffic being light. The pull toward the HOV answer comes from carrying over the diamond-lane habit that occupancy alone earns access, but a red transit lane is controlled by its transit-only signs and markings, and the number of passengers on board changes nothing about who may drive there.

Why the others miss

The traps in the wrong answers

B. Use the lane whenever you're carrying two or more passengers as a high-occupancy vehicle.

Red pavement reserves the lane for buses and other authorized transit vehicles regardless of how many people are riding in a private car; a full car has no more claim to a color-coded transit reservation than a single driver does. Borrows the idea of occupancy-based access from diamond-marked HOV lanes and applies it to a red transit lane, which is instead controlled by its posted transit-only signs and markings.

C. Use the lane during off-peak hours when transit service is running lightly.

The posted regulatory signs set when and how a red-colored transit lane may be used, and off-peak hours alone don't open it to private traffic; you follow what the signs say and otherwise stay out. Applies a peak-hour bus-lane habit from signed curbside lanes to a color-coded transit reservation, assuming reduced service automatically opens the lane rather than reading what the posted signs actually allow.

D. Treat the red pavement as a warning of construction or roadwork ahead.

Red pavement here reserves the lane for buses and authorized transit vehicles and does not signal a work zone; construction and roadwork are marked in orange, not red. Reads any bright pavement color as a hazard alert, confusing red transit-lane coloring with the orange used for work-zone signs and channelizing cones.
