*54 OPINION
Appellants Sam and Marie Andolino sued the State of Nevada, the Department of Highways, the Nevada Highway Patrol, the Metropolitan Police Department, the City of Las Vegas, and Clark County for negligence. The district court granted motions for summary judgment in favor of all defendants on the ground that they were immune from suit for their discretionary acts. NRS 41.032(2). We reverse with respect to the state and the highway department, and affirm with respect to the other defendants.
In January, 1974, a record snow storm swept the Las Vegas metropolitan area creating hazardous road conditions. Road crews were dispatched to plow the highway and aid local *55 authorities in handling traffic congestion. The majority of Interstate 15, the main north-south freeway through Las Vegas, was open to travelers. However, the offramp leading to downtown Las Vegas was covered with snow and ice. Plaintiffs were injured when their car entered the offramp, spun out of control, and collided with a guardrail.
The state owes an affirmative duty to keep the highways reasonably safe for the traveling public. State v. Kallio,
By contrast, the Nevada Highway Patrol, Metro Police Department, City of Las Vegas, and County of Clark owed no duty to maintain the highway. NRS 481.027. When the duty to maintain is placed upon one governmental agency, any action
*56
by another agency to assume voluntarily the burden of maintenance is discretionary and therefore precludes liability. NRS 41.032(2); LaFever v. City of Sparks,
We affirm summary judgment with respect to the Nevada Highway Patrol, Metropolitan Police Department, City of Las Vegas, and County of Clark. Because the decision regarding which areas of the freeway to plow was an operational one, the doctrine of sovereign immunity does not bar suit with respect to the State of Nevada and the Department of Highways. The order granting summary judgment in favor of these parties is therefore reversed, and the case is remanded for further proceedings.
Notes
NRS 481.027 prior to its amendment provided: “It is intended by this section that the Department of Highways shall retain its control over the physical aspects of the public highways.”
NRS 41.031 provides: “The State of Nevada hereby waives its immunity from liability and action and hereby consents to have its liability determined in accordance with the same rules of law as are applied to civil actions against natural persons ...”
NRS 41.032(2) provides: “No action may be brought . . . which is based upon the exercise or performance or the failure to exercise or perform a discretionary function or duty . . .”
We express no opinion as to whether or not the alleged acts constitute negligence.
