Lines on the road tell you where you may change lanes and pass. Color tells you direction: white lines separate traffic moving the same way, and yellow lines separate traffic moving in opposite directions.

Know the rule

When a sign or signal requires you to stop, stop before the stop line or, if there is one, the crosswalk. Yield to pedestrians in crosswalks—and remember that not all crosswalks are marked.

Reversible lane

A lane that carries traffic one direction at some times and the opposite direction at others, usually marked by double broken yellow lines. Check signs or signals before using it.

Put it into practice

On a two-lane road there's a solid yellow line on your side and a broken line on the other. You may not pass—but you may still cross the line to turn left into a driveway when it's safe.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

A broken white line between lanes traveling the same direction means you
  1. may change lanes if it is safe
  2. are discouraged from changing lanes
  3. may not change lanes at all
  4. may cross it only to exit the road

Answer: may change lanes if it is safe

A broken white line means you may cross it to change lanes if it is safe to do so.

Handbook p. 82 ↗
Double solid white lines between lanes of traffic mean
  1. you may pass only on the left
  2. lane changing is prohibited
  3. you may pass only if a broken line is nearby
  4. the lane ends ahead

Answer: lane changing is prohibited

Double solid white lines prohibit lane-changing across them.

Handbook p. 82 ↗
If there is a solid yellow line on your side and a broken yellow line on the other side, you
  1. may pass if it is safe to do so
  2. must stop before proceeding
  3. may not pass
  4. may pass if no traffic is coming

Answer: may not pass

You may not pass if the solid yellow line is on your side; passing is allowed only from the side with the broken line.

Handbook p. 83 ↗
Two solid yellow lines between opposing lanes of traffic mean
  1. only traffic going uphill may pass
  2. passing is allowed if the road ahead is clear
  3. passing is allowed at low speeds
  4. neither side may pass

Answer: neither side may pass

Two solid yellow lines mean neither side of traffic may pass, though you may still cross to enter a driveway.

Handbook p. 83 ↗
On a reversible lane, a red 'X' displayed overhead means
  1. you cannot use that lane
  2. you must use that lane immediately
  3. the lane is for buses only
  4. the lane is temporarily a passing lane

Answer: you cannot use that lane

On reversible lanes, a green arrow means you may use the lane and a red X means you cannot use it.

Handbook p. 83 ↗
Edge lines, the solid white lines along the side of the road, mark the outside edge of the travel lane.
  1. True
  2. False

Answer: True

Solid white edge lines show drivers where the outside edge of the travel lane is located.
