What does the obligation to stop mean?

The road sign "Obligation to stop" means that you must always stop at the intersection. Violating the obligation to stop is very serious and can lead to you having your driver's license revoked. There is a point in the obligation to stop sitting there. The idea is that you should stop and then look carefully before continuing. If there is a stop line, you must stop at this, otherwise you must stop immediately before entering the intersecting road. The fact that you should stop right at intersections with a duty to stop is to see and be seen as well as possible. In the event of a queue, you cannot stop behind the car in front and then join in as they drive, but each driver must make their own stop before they are allowed to drive on.
