Final answer:
A painted median consists of double solid yellow lines on both sides of a road, and it is used to separate opposite directions of traffic and prevent lane changes. Crossing or changing lanes within a painted median is strictly prohibited.
Step-by-step explanation:
A painted median consists of double solid yellow lines on both sides of a road. It is commonly used to separate opposite directions of traffic and indicate that it is unsafe to cross or change lanes within the designated area.
For example, on a highway, the painted median helps prevent head-on collisions by creating a physical barrier between traffic moving in opposite directions.
In addition to the yellow color, the double solid lines also signify that crossing or changing lanes is strictly prohibited within the painted median area.
