The **continuous line** on the road is a signal that **prohibits drivers from crossing it or driving over it**. This means that under no circumstances should this line be crossed. The main function of the continuous line is to maintain safety on the road, preventing dangerous maneuvers such as overtaking in areas where visibility is limited or where oncoming traffic could pose a risk.


- The continuous line also indicates that one should not drive to the left of the line on two-way roads, reinforcing the separation between opposing traffic flows.
- In some cases, the continuous line may be wider than usual, indicating the presence of a special lane reserved for certain types of vehicles.

Therefore, the correct answer is that **a continuous line should never be crossed**.
