What does a solid white line on the road indicate?

Correct answer

It marks the edge of the road or separates lanes of traffic going the same direction where lane changes are discouraged

  1. A You may cross it freely to change lanes anytime
  2. B It marks the edge of the road or separates lanes of traffic going the same direction where lane changes are discouraged
  3. C It separates opposing traffic
  4. D It means stop

Why this is the answer

A SOLID WHITE line marks the EDGE of the road (the right edge/shoulder line) OR separates lanes of traffic going the SAME direction where changing lanes is DISCOURAGED (you should stay in your lane). DMV/permit test. WHITE LINES separate traffic moving in the SAME direction; YELLOW lines separate traffic moving in OPPOSITE directions. A BROKEN (dashed) white line means lane changes ARE permitted when safe; a SOLID white line means lane changes are discouraged (and a DOUBLE solid white line means do not cross/change lanes). Knowing white-line meanings (same direction; solid = discouraged, broken = allowed) is commonly tested.
