This sign was spotted on an Indiana backroad. As you’d expect, funerals can be heavily-attended occasions, among the largest events held at Amish homes.
Another time to stay particularly alert is on Sunday morning when Amish travel to church services, and later in the day when Amish youth are traveling to their groups and singings. This can mean a swarm of buggy traffic, especially in larger communities with many churches and with youth sometimes traveling cross-settlement to their groups or dates.
The sign could probably use a little punctuation (it reminded me of the confusing SLOW CHILDREN PLAYING signs you often see in suburban neighborhoods).
