In Riddle v. Ariz. Oncology Servs., Inc., 186 Ariz. 464, 467, 924 P.2d 468, 471 (App. 1996), an injured motorist sued an employer after colliding with a car being driven by the employer's impaired employee. The employer had ordered the employee to leave work because she had been "conspicuously intoxicated and incapable of performing her work duties." 186 Ariz. at 465, 924 P.2d at 469. Relying in part on Restatement 317, we found the employer had owed no duty of care to the injured motorist even though the employer had known the employee had a history of drug abuse and "knew or should have known" that she could not safely operate a motor vehicle when she left the premises. 186 Ariz. at 468, 924 P.2d at 472.
