Louisiana bars UM stacking by statute, with one exception for non-owned vehicles
Louisiana's rule is in La. R.S. 22:1295: paragraph (1)(a) sets the required coverage and the rejection form, paragraph (1)(c) is the antistacking and priority rule, and paragraph (2)(b) defines an underinsured vehicle. The minimum limits are in 32:900, and the two-year deadline in Civil Code article 3493.1.
