While driving at night on a divided multi-lane roadway, you observe a solid yellow line painted along the pavement edge to your left and a solid white line painted along the pavement edge to your right. Which of the following statements correctly identifies the function of these pavement edge lines?
- They mark the outer boundaries of the travel lanes, showing that traffic is traveling in the correct direction with yellow defining the left border and white defining the right border.Answer
- BThey indicate that lane changes and passing maneuvers are prohibited across all travel lanes between the two lines.
- CThey show that the left lane and right lane are carrying traffic flowing in opposite directions.
- DThey designate the left lane exclusively for emergency vehicles and the right lane exclusively for commercial trucks.
Answer
Pavement edge lines define the boundaries of the roadway: a solid yellow line marks the left edge of a one-way roadway or divided highway, while a solid white line marks the right edge, guiding drivers safely within the legal travel pavement.
Solid pavement edge lines (delineators) define the legal boundaries of travel lanes. On divided highways and one-way roadways, a solid yellow line is placed along the far left edge to mark the median boundary, and a solid white line is placed along the far right edge to mark the right shoulder boundary. Seeing yellow on the left and white on the right confirms the vehicle is traveling in the correct direction.
