When a sign imposes the **obligation to stop**, it is essential to understand that you cannot resume driving until the obligation established by that sign is fulfilled. This means that the driver must wait until the conditions indicated by the sign have been completely met.

- **Continuous transverse lines**: These lines indicate that all vehicles must stop and follow the indications of associated signals, such as traffic lights, pedestrian crossings, or instructions from traffic officers. The line itself does not require stopping; it is the sign that establishes the obligation.

- **Stop sign on the road**: When there is a Stop sign, the driver must stop before the stop line to yield to other vehicles traveling on the road they wish to enter. You cannot continue until you have yielded safely.


- **Signals from a vehicle**: For example, if a police vehicle emits a flashing red or yellow light, the driver must stop and follow the officer's instructions. You cannot resume driving until the officer indicates.

In summary, you cannot resume driving until the obligation established by the sign is fulfilled, thus ensuring safety and order in traffic.
