Owners argues that the district court improperly applied a heightened duty to Denault because she was the sober designated driver. North Dakota does not impose a heightened duty by statute; a person driving a vehicle must operate “in a careful and prudent manner.” The North Dakota courts have not imposed a heightened duty on designated drivers by common law. Other jurisdictions affirmatively have rejected such a duty, citing the potential that heightened exposure to liability would chill designated drivers from performing a valuable service.
In Tennessee, for example, a party assumed no affirmative duty merely because of his status as a designated driver to aid or protect an intoxicated passenger who rode unrestrained in the bed of a pickup truck, “exited” the truck, and died on the road. Downs ex rel. Downs v. Bush (Tenn. 2008). The court observed that “[t]o hold a driver liable for the irresponsible actions of an intoxicated passenger would cut against this important social policy of encouraging the use of designated drivers.” In Vermont, a sober driver of a pickup truck breached no duty of care to an intoxicated passenger who knelt on a toolbox in the bed of a pickup truck, reached his arm into the passenger side of the cab, and died when he fell under the truck. Collins v. Thomas (Vt. 2007). In Louisiana, a sober driver owed no duty to protect an intoxicated passenger who asked to exit the car on the side of a highway before he was struck and killed while walking into traffic. Cardella v. Robinson (La. Ct. App. 2005)….
[T]he court imposed a heightened duty on Denault because of her role as the sober designated driver for a group of intoxicated passengers. Most of the court’s rationale for assigning Denault a greater proportion of fault for Hiltner’s injuries was tied to her status as the designated driver, not to the manner in which she operated the vehicle.
As best we can tell, the district court relied on § 324 of the Restatement [of Torts] and the duty imposed on an actor who “takes charge of another who is helpless adequately to … protect himself.” This actor must “exercise reasonable care to secure the safety of the other while within the actor’s charge.” The court quoted this section in a footnote; the placement of the footnote shows that the district court seemed erroneously to equate § 324 with Denault’s duty to “exercise reasonable care in driving the vehicle.”
The findings of fact are not sufficient to support apportioning greater fault to Denault based on a duty under § 324. The district court referred to Denault “taking charge of obviously intoxicated passengers,” but did not specify what findings of fact would support that conclusion. The court found that Denault told Hiltner twice to get off the trunk of the vehicle, and that Hiltner twice refused and told Denault that she would be “fine.” These findings suggest that Denault did not “take charge” of Hiltner.
The district court also did not find that Hiltner was “helpless.” One court has found that an intoxicated passenger with a blood-alcohol content of 0.38 was “helpless” after consuming alcohol to the point of being “semiconscious,” while an “impaired” person who drank six beers in five hours was not. The district court found that Hiltner’s blood-alcohol content was 0.081 shortly after the accident, but did not opine one way or the other on whether she was “helpless” for purposes of § 324.
None of this is to say that the district court erred in concluding that Denault was “at fault” in the accident. Owners does not challenge that determination. But we cannot escape the conclusion that the apportionment of fault among the participants was influenced materially by Denault’s status as the sober designated driver. This allocation of increased responsibility to Denault was either infected by legal error or unsupported by findings of fact that are necessary to justify it. We therefore conclude that the judgment should be vacated and the case remanded for further proceedings.
