True or False: A solid white line should not be crossed while changing lanes.

A solid white line indicates that lane changes are discouraged. This marking is used to signal to drivers that crossing the line could be unsafe or is not advisable due to various factors, such as traffic conditions or the roadway's layout. The intent behind this rule is to promote safety and reduce potential conflicts between vehicles.

In contrast, a broken white line allows for lane changes when it's safe to do so, indicating that their crossing is permitted under appropriate circumstances. Therefore, when a solid white line is present, it is an important visual cue for drivers to be cautious and to remain in their lane, enhancing overall road safety.
