The white-topped buggies are associated with the Nebraska Amish, although most of them reside in Pennsylvania rather than Nebraska.
The white buggies make the Nebraska Amish more visible on the road. This helps other drivers see them easily, especially in low-light conditions or poorly lit areas, making travel safer for everyone.
The Nebraska Amish started in 1881 as a conservative breakaway from the Byler Amish, who had initially split from the mainstream Amish in 1849.
On a side note, the Byler Amish travel in yellow buggies. It seems that both groups adopted a different buggy color after splitting from the main group.
Nebraska Amish men wear brown trousers without suspenders, trousers are laced up in the back instead and shoulder-length hair. They also wear white shirts, brown vests, and jackets.
Women don’t wear bonnets. Instead, they use tie-on flat straw hats or black kerchiefs while working outside.
Regarding technology use, the Nebraska Amish are almost as restrictive as the Swartzentruber Amish. They don’t use motorized equipment and indoor plumbing.
Additionally, their houses must not have projecting roofs.
