Amish and motorists share the road. 300 years of experience produced rules:
For Motorists
Don't honk (horse startles). Pass slowly, wide. Don't photograph. Don't stop to chat.
For Amish
Right edge. Don't take the whole lane. Lanterns on. On hills — yield. Clean manure off road.
Main Rule
Patience. Both sides. Both are people. Both on the same road.
