A two-way road has the single broken yellow center line shown. What does the marking permit?
Correct answer: Passing from either direction when the maneuver is otherwise safe and lawful.
A broken yellow center line identifies a passing-permitted section in both directions. It does not remove the need for a clear view, a safe gap, and compliance with other restrictions.

You are in the lane beside the solid yellow line in this pair. What does that mean for passing a slower car?
Correct answer: You must not cross the center lines for that pass.
The center-line pattern applies according to the line nearest your lane. A solid yellow line on your side prohibits passing across it.

You are beside the broken yellow line, with a solid yellow line beyond it. How does the marking affect a proposed pass?
Correct answer: Passing may be allowed from your side if traffic, visibility, and other rules permit.
A broken line on your side permits a pass when safe and otherwise lawful. Drivers on the solid-line side do not have the same passing permission.

What do the two solid yellow center lines tell drivers who want to pass an ordinary car?
Correct answer: Passing across the lines is prohibited in both directions.
Double solid yellow lines establish a no-passing section for both traffic directions. This item concerns overtaking a car, not a separate left-turn maneuver.

You need to turn left into a driveway across solid yellow center lines, with no sign prohibiting the turn. What does Idaho's manual say?
Correct answer: The lines do not prohibit this driveway turn, but you must wait until it is safe.
Idaho distinguishes a left turn into a driveway from passing across solid yellow center lines. The turn still requires a safe gap and yielding to conflicting traffic.

What does the broken white line between the two same-direction lanes indicate?
Correct answer: A lane change is permitted when it can be made safely.
A broken white line allows lane changes but does not give the changing driver priority. Check traffic and signal before crossing it.

What does the single solid white line between these same-direction lanes communicate?
Correct answer: Avoid changing lanes across the line.
Idaho’s manual directs drivers to avoid lane changes across a single solid white lane line. It distinguishes this from double solid white lines, where lane changes are prohibited.

In the diagram, what does the solid white line along the far-right edge identify?
Correct answer: The edge of the roadway or shoulder boundary.
The solid white edge line shows the outside edge of the travel lane. It is not a center line or another ordinary through-lane boundary.

What is the main purpose of the center lane marked with opposing left-turn arrows and solid/broken yellow boundaries?
Correct answer: Left turns by traffic from either direction.
Idaho reserves this shared center lane for left turns, or U-turns where permitted, by traffic from either direction. Do not travel along it or interfere with another vehicle preparing a turn.

Two solid white lines separate your lane from a same-direction lane. How should you treat that boundary?
Correct answer: Do not cross the double solid white lines to change lanes.
Idaho's manual distinguishes double solid white lines from a single solid white line: the double line prohibits lane changing.

What does the marked area beside the solid white boundary represent?
Correct answer: A lane designated for bicycles traveling in the same direction as adjacent traffic.
The bicycle symbol and solid white boundary designate bicycle space, not an ordinary car lane. Look carefully for riders and obey applicable turn and crossing rules.

Near an intersection, the bike-lane boundary becomes dashed. You need to move right for a turn, and a bicyclist already occupies that area. What should you do?
Correct answer: Yield to the bicyclist, then merge only when safe.
Dashed bike-lane boundaries identify a location where turning drivers and bicyclists may merge. Idaho’s guidance requires a right-turning driver to yield when a bicyclist is already in that area.
