South Dakota minimum coverage: 25/50/25

South Dakota requires liability coverage on every registered vehicle. The legal floor:

$25,000 bodily injury per person
$50,000 bodily injury per accident
$25,000 property damage per accident

Minimum coverage keeps you legal, not necessarily solvent: the average new truck costs more than $25,000 to replace, so one at-fault accident can outrun your property-damage limit.

UM/UIM also required.
