I was wondering this as well for Texas. We will need to do something for when we make stops. Maybe just hazard lights and we could connect some of the lights to those.
Our stop sign on the side does not currently do anything which is another to-do list item. The stop sign itself is missing completely, but we may need to have something other that anyway to not break any road laws. Something like "WATCH FOR CHILDREN" would do rather than "SLOW CHILDREN" Lol
