What does a broken white line signify?

A broken white line is used to indicate that there is a lane separation for traffic moving in the same direction, and it allows drivers to cross the line when it's safe to do so. This means that if you're within a lane and you wish to change lanes to overtake another vehicle or for any other reason, you are permitted to do so as long as you ensure that it is safe. This is in contrast to solid lines, which indicate that lane changes are not allowed.

Understanding this context helps convey the importance of assessing the situation before changing lanes while also confirming that drivers must always prioritize safety for themselves and others on the road.
