J. On the evening of May 21, 1976, forty to fifty young people attended a beer party to celebrate their approaching graduation from high school. This litigation arises out of the tragic aftermath of that party. The festivities took place at the McDonald residence in North Chelmsford, located on Tyngsboro Road (Route 3A), a State highway. The hosts were the two teenaged sons of the defendant, Mildred E. McDonald

There was room for limited parking in the driveway on the McDonald property, and there was additional parking available in a retail parking lot a short distance away. Most of the guests used one of these two locations for parking. Nevertheless, three cars were left parked in front of the house parallel to Tyngsboro Road on a shoulder 3 with their lights out. One of the three vehicles, the first in the line of three, left briefly and returned around 11:30 p.m. The driver, Frederick Schnepper, parked his vehicle again in approximately the same location parallel to Tyngsboro Road. He left the vehicle, without lights, with approximately twelve inches protruding onto the travelled portion of the road 4 . Joseph Polak, seventeen years old, remained asleep in the back seat of the car. After a short while, a vehicle, driven by one Lester Adair, came along Tyngsboro Road at a high rate of speed, left the highway, struck the third vehicle in the line of parked cars, went around the second, and struck the rear of the Schnepper vehicle in which Polak was sleeping. The Schnepper vehicle was struck with such force that it was pushed a considerable distance and demolished. The Schnepper vehicle caught fire. Polak eventually died of the injuries he received in the accident.
Suit was brought on behalf of Polak’s estate against Adair, the owner of the vehicle Adair was driving, the owners of the three parked vehicles, the manufacturer of the Schnepper vehicle, and an establishment alleged to have served liquor to Adair. McDonald was also sued. A jury found liability on the part of Adair, the owner of the vehicle Adair was driving, and McDonald. A motion for judgment notwithstanding the verdict was filed by McDonald and allowed, and from that allowance the plaintiff has appealed.
Under this standard, we think the judge was correct in concluding that the evidence was insufficient to justify the jury verdict. We interpret the judge’s ruling to be that a sufficient causal link had not been established between the breach of McDonald’s duty to her guests and the happening of the fatal accident. We would affirm the decision, however, if proper on any ground.
Ezekiel
v.
Jones Motor Co.,
McDonald, as the owner of the premises to which Polak was invited, had a duty to exercise reasonable care for his safety.
Mounsey
v.
Ellard,
McDonald contends that the duty she owed to invitees was not so broad as to include a duty to warn them not to park along the highway. She points out, apparently correctly, that there is no precedent for the imposition of liability in these exact circumstances. That would not be dispositive, however, if, looking to established principles of the law of negligence, we were to conclude that a jury could reasonably find in the circumstances that there was a duty to warn and that a breach of that duty occurred.
There was evidence on which the jury could properly find that there was some danger to cars parked along the highway as they were at the time of the accident and that McDonald, aware of the danger, did not effectively warn her guests of it. For a definition of the exact scope of her duty in these circumstances, we look to the relationship of the parties. By giving her sons permission to extend to their group of friends the invitation to attend a party at her home, McDonald placed herself in a special relationship to those guests. The obligations she assumed were those which, considering customs and accepted social norms, one would reasonably expect her to fulfill, no more and no less. See
Irwin
v.
Ware,
If a risk is of such a nature that it would be obvious to persons of average intelligence, there is, ordinarily, no duty on the part of the property owner to warn of the risk.
Letiecq
v.
Denholm & McKay Co.,
We think that whatever danger was created by the parking of cars adjacent to the highway ought to have been so obvious to the ordinary person that McDonald, in the exercise of reasonable care, was not required to warn her guests of that danger. True, the guests were young, mostly in their late teens and, arguably, not fully conscious of all the dangers that were present. See
Mullins
v.
Pine Manor College,
Judgment affirmed.
Notes
Now Mildred E. McDonald Whitney.
Tyngsboro Road is a two-lane road with a center line and fog lines separating the travelled portion from the shoulder. Parking on a State highway is prohibited. See 19 Code Mass. Regs., Part 10, Registry of Motor Vehicles Rules and Regulations for Driving on State Highways, art. II, § 2 (1976). See now 720 Code Mass. Regs. § 9.03 (2) (1979).
The twelve-inch protrusion was not a significant factor in the accident.
