What do yellow lines on the road indicate?

Yellow lines on the road are used primarily to separate lanes of traffic traveling in opposite directions. This is a crucial element of road safety, as these lines help drivers understand which side of the road they are supposed to be driving on. When you see a solid yellow line, it signifies that passing is prohibited from that side, while a broken yellow line indicates that passing is allowed when safe.

This use of yellow lines is distinct from the function of white lines, which are used to separate lanes of traffic moving in the same direction, and does not pertain to parking regulations or turning restrictions. Therefore, understanding the meaning of yellow lines is vital for maintaining proper lane discipline and ensuring the safety of all road users.
