Long distance buses (e.g. Flixbus, Sadem, National Express..) do not have seats suitable for safe use by children. They do not seem to be equipped for the use of approved child seats or seat belts suitable for children or infants.

If these services were available, however, the communication on their websites is not clear and immediate.

If a family with small children wanted to choose this mode of transport for a long-distance trip, how could they do it safely?

What solutions could be proposed and planned?
