Pavement markings
A 3-minute lesson from the New Mexico course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Lines and symbols on the road divide lanes, tell you when you may pass or change lanes, show which lanes turn, mark pedestrian walkways and show where to stop. Color tells direction: white separates same-direction traffic, yellow separates opposite directions.
Know the rule
Solid lines along the side of the road show where the edge of the road is.
On a two-lane road you see a solid yellow line on your side and a dashed line on the other. You may not pass here, but you may cross it 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.
