How to go to the toilet on a long-distance bus? Is there a bathroom in the car?

Some long-distance buses are equipped with toilets, but the sanitary conditions will be very poor, so emergency use will be enough.

But now most long-distance buses have no toilets. In this case, the driver will drive for about 2-3 hours, rest in the service area of the expressway, and then get off and go to the toilet during the rest. If the car doesn't take the highway, in fact, on ordinary provincial roads or large roads, drivers will stop regularly to let passengers rest and go to the toilet. If you are in a hurry, ask the driver how long it will take to stop. In this way, after the driver knows, he will rest and park in the right place, and then go to the toilet after parking.
