What do yellow centerlines ordinarily separate?
Correct answer: Traffic moving in opposite directions.
Yellow centerlines separate opposing traffic. Whether passing is permitted depends on the line pattern, signs and conditions.

Two adjacent travel lanes are separated by white lane markings. What does that color normally indicate?
Correct answer: The lanes carry traffic in the same direction.
White lane lines normally separate traffic traveling in the same direction. Additional signs and markings determine the use of each lane.

A broken white line separates your lane from the next lane. What does the marking permit?
Correct answer: A lane change when it is safe and otherwise allowed.
A broken white line allows safe lane changes. It does not replace observation, signaling or yielding to vehicles already in the lane.

A broken yellow centerline is on your side. Assuming no other restriction, what does it indicate about passing?
Correct answer: Passing may be allowed if the entire maneuver can be made safely.
A broken yellow line can permit passing, but a driver still needs a safe view, space and a legal opportunity to complete the maneuver.

A solid yellow line is next to your lane and a broken yellow line is next to opposing traffic. You want to overtake an ordinary moving car. What does your line prohibit?
Correct answer: Crossing the solid line to pass that car.
For this ordinary car-passing situation, the solid line on your side marks a no-passing restriction. Separate permitted turns and bicycle-passing exceptions are different situations.

You start a lawful pass where the broken yellow line is on your side. What must you plan for before that line becomes solid?
Correct answer: Return safely to your lane before the broken section ends.
Plan a pass that can be completed safely within the permitted section. Do not start a pass that depends on continuing into a prohibited stretch.

A solid yellow centerline is present and you need to turn left into a private driveway. Is that line by itself a blanket ban on the turn?
Correct answer: No; the handbook permits crossing it for a safe left turn into a driveway.
The handbook allows a safe left turn across a solid yellow line into an alley, private road or driveway. Yield, check for other restrictions and avoid conflicts; this is different from passing a car.

What should green-painted areas associated with a bicycle lane alert you to?
Correct answer: A designated bicycle area that makes bicycle travel more visible.
Green pavement highlights bicycle space and possible interactions with cyclists. Look carefully and do not assume a motor vehicle may occupy it freely.

You see a bicycle symbol with chevrons painted in a travel lane. What is the purpose of this sharrow?
Correct answer: Remind users that motorists and bicyclists share the lane.
A sharrow identifies shared use; the lane may be too narrow to travel side by side safely. A cyclist may use the lane's center to avoid hazards or improve visibility.

Broken lines appear where a bike lane and turning traffic cross paths. What should this conflict zone lead you to expect?
Correct answer: Drivers and bicyclists may cross each other's paths.
Conflict-zone markings highlight an area where travel paths meet. Check for cyclists and yield as required rather than assuming the broken line gives priority.

A white diamond is painted in a travel lane. What should you check before using it?
Correct answer: The signs describing which vehicles or occupants qualify.
A diamond can mark a restricted-use lane. Read the posted conditions instead of assuming every diamond lane has identical requirements.

An HOV lane's sign requires three occupants during the current hours. You and one passenger are in an ordinary car with no exemption. May you use it?
Correct answer: No; two occupants do not meet the posted three-person requirement.
Follow the occupancy, hours and vehicle rules shown on the signs. This scenario has two occupants, not the required three, and no exception.

A sign identifies a transit lane. How should you decide whether your vehicle may use it?
Correct answer: Read the posted permitted uses and restrictions.
Transit lanes may allow only transit vehicles or limited use by other authorized vehicles. Their posted rules determine who may enter.

What is the purpose of a shared center two-way left-turn lane?
Correct answer: Left turns from either direction, not through travel or passing.
The shared center lane serves left turns from both directions. Do not use it as a passing lane or a lane for continuing along the road.

A lane is designated reversible. What should you understand about its permitted travel direction?
Correct answer: It can change at different times; follow the current controls.
A reversible lane carries traffic in one direction at some times and the opposite direction at others. Observe its signs and lane-control signals before entering.

A bicycle lane reaches an intersection, but green paint does not connect it across the junction. Does the lack of connecting paint erase the bicycle lane there?
Correct answer: No; the lane continues through the intersection.
The handbook states that a bike lane extends through an intersection even when paint does not connect its two sides. Watch for cyclists whose path your turn may cross.
