What does a yellow dashed line on the road indicate?

[SanFinley]

A yellow dashed line at the center of the road is a marking used to separate opposing traffic flows, typically painted along the road's midline. The yellow dashed line indicates that crossing is permitted, allowing drivers to overtake or make turns when it is safe to do so. The differences between yellow and white lines are as follows: Yellow lines: Yellow lines are used to separate lanes of traffic moving in opposite directions, usually painted down the middle of the road like a divider, splitting the road into two directions: Whether it's a single or double yellow line, if it's solid, crossing is strictly prohibited. Drivers should not cross the line unless absolutely necessary. Whether it's a single or double yellow line, if it's dashed, overtaking or making U-turns is allowed when safe. Single yellow lines are generally used on roads with up to four lanes (including bicycle lanes), while double yellow lines are used on wider roads. White lines: White lines are used to separate different lanes of traffic moving in the same direction. Dashed white lines indicate that lane changes are permitted, while solid white lines mean lane changes are not allowed and drivers should not switch lanes arbitrarily.
