What does a yellow center line normally separate on a two-way roadway?
Correct answer: Traffic moving in opposite directions
Yellow center lines separate opposing traffic. Their solid or broken pattern then tells you whether crossing for passing is permitted.

A broken yellow center line is beside your lane. What does it mean about passing across it?
Correct answer: Passing may be allowed when otherwise lawful and safe
A broken yellow center line can permit passing with care. It does not remove sight-distance, oncoming-traffic or other legal restrictions.

There is a solid yellow line beside your lane and a broken yellow line beside opposing traffic. May you cross to pass?
Correct answer: No; your side is the no-passing side
For a solid-and-broken yellow pair, passing across the center line is prohibited from the solid side. Traffic next to the broken side may pass with care when otherwise lawful.

The yellow line nearest you is broken; the line beside opposing traffic is solid. Which statement is correct?
Correct answer: You may pass across it if the maneuver is lawful and safe

What do two solid yellow center lines mean for a driver wanting to overtake by entering opposing traffic?
Correct answer: Passing across the lines is prohibited in both directions
Double solid yellow center lines mark a no-passing zone for both directions. This question concerns passing, not separate rules for a lawful driveway turn.

Two adjacent traffic lanes are separated by a white lane line. What do they normally have in common?
Correct answer: They carry traffic in the same direction
White lane lines separate lanes traveling in the same direction. Read the line pattern and signs to determine whether a lane change is appropriate.

What does a normal broken white line between same-direction lanes indicate?
Correct answer: A lane change may be made with care
A broken white lane line permits crossing with care. Signal, check the adjacent lane and blind spot, and change only when there is a safe opening.

A single solid white line separates two same-direction travel lanes. What does that marking communicate?
Correct answer: Crossing the lane line is discouraged
A single solid white lane line discourages crossing. Do not confuse it with a double solid white line, which is used where crossing is prohibited.

You are approaching your exit, but double solid white lane lines separate you from the exit lane. What is the correct decision?
Correct answer: Do not cross them; continue to a lawful route
Double solid white lane lines mark a prohibition on crossing. A missed exit is not a reason to make an unsafe or prohibited last-second lane change.

A center lane has left-turn arrows for both directions, with broken yellow lines inside solid yellow boundaries. What is it for?
Correct answer: Left-turn maneuvers by traffic from either direction
Those markings identify a two-way left-turn lane. It is not an extra through or passing lane, and opposing drivers may also be using it to turn.

A lane has broken double yellow lines on both sides. What must you check before using it?
Correct answer: The signs and lane-control signals for its current direction
Broken double yellow boundaries identify a reversible lane. Signs or lane-use control signals show how it may be used at the current time.

A solid white line runs along the outside right edge of the roadway. What does it mark?
Correct answer: The right-hand edge of the roadway
A right edge line is normally solid white. It helps identify the roadway edge, especially when visibility is poor; it does not create another through lane beyond it.

On a divided highway in your direction of travel, a solid yellow line follows the left roadside edge. What does it mark?
Correct answer: The left-hand edge of that roadway
A solid yellow left edge line is used on divided highways, one-way roadways and ramps. Its position distinguishes an edge line from a center line separating opposing lanes.

A wide dotted white line separates your lane from a lane signed EXIT ONLY. What should you plan for?
Correct answer: The adjacent lane leaves the through roadway
Dotted white lane-drop markings help distinguish a lane that becomes a mandatory exit or turn from continuing through lanes. Read the signs early and choose your lane safely.

The triangular neutral area between freeway traffic and an exit ramp is outlined with channelizing lines. What is its purpose?
Correct answer: To separate and guide traffic, not serve as an extra lane
Channelizing lines define the neutral gore area and guide the paths of through and exiting traffic. Plan ahead rather than using this space as a shortcut.

What does this pavement marking indicate?
Correct answer: Where approaching traffic must yield or stop when required
A yield line marks where approaching vehicles should yield or stop when necessary; the triangles point toward approaching traffic.
