(in the US) They indicate a no passing zone. The white lines indicate multiple lanes of travel in the same direction, while the yellow lines indicate opposing lanes of travel.
Roads are an example of intersecting lines in the real world.
Skew lines do not lie in the same plane. Parallel lines do lie in the same plane. That's the difference. Neither of them are intersecting, so it can be confusing. Think of 2 highways that 'cross' with an overpass. While a highway is not a 'line' this should help you to understand. The 2 highways do not intersect; one goes 'under' and one goes 'over', so they are skew. This is different than two roads that have an intersection, with a traffic light or stop sign. Even the 'road' term is the same as the Math term!

Yes In math, it can also be lines, not just roads.
When two roads cross, they form an intersection.
The yellow lines refer to parking controls on UK roads. When double yellow lines are in force, you can't. (note that double yellow lines are not always operational at all times. The restriction prevents parking on or adjacent to double yellow lines. There is no mention in the regulations about which side of the yellow lines and therefore they are effective for vehicles parked on pavements or verges. Look at the Highway code text next to the pictures of double yellow lines in the Road Markings section.

Well, in the US, we do have roads with no center markings. You stay as far right as possible without sliding off the berm. In many rural areas with no center markings, vehicles slow and stop to let another driver pass on narrow roads or one lane bridges. But without solid or dash lines---as was the norm in many communities pre-1950s, drivers took their chances about when and where to pass. There were many head on collisions, many deaths. So the solid yellow, double solid yellow, and broken dash yellow were devised as common visual reminders of how drivers should behave in different situations.
Maps usually show roads as different coloured lines depending on their importance.
I can give you several sentences.The two roads run parallel to one another for several miles.The scientist traveled to a parallel dimension.Two parallel lines will never meet.
Lane markings on roads are very important; they let the driver know the rules of the road. Solid centerlines usually yellow or white indicate the driver should not cross the line and stick to their side of the road to prevent accidents.
In the US, both solid white lines and double white lines are used to mark areas of prohibited lane changes in multi-lane traffic. Broken (dashed) yellow lines, solid yellow lines, and double yellow lines are used to separate traffic moving in opposite directions.
The two white lines on the roads in Perth, WA mean that you are on a 2-way road. You may not cross double lines, whether they are white or yellow, or you will find yourself in the path of another auto going the opposite way.
Roads typically consist of paved surfaces made of asphalt or concrete, designed for vehicles to travel on. They can vary in width and complexity, from narrow country lanes to wide highways with multiple lanes. Roads often feature markings, such as lines for lanes, pedestrian crossings, and signage to guide drivers. Surrounding areas may include sidewalks, greenery, or urban structures, depending on the environment.
Roads that run north to south are typically referred to as "north-south roads" or "vertical roads."
