In one paragraph

Arizona's SB 1320 (Laws 2025, Ch. 19) amends the Title 28 definition of "implement of husbandry" (A.R.S. 28-101) to include agricultural implements and vehicles that use an automated driving system or are autonomous. Such equipment, used solely for agriculture and only incidentally on highways (for example between farms or to a repair site), is treated like other farm implements under motor vehicle law.
