delivered the opinion of the court:
The claimant, Ferd Humphrey, was injured late in the evening in a single-vehicle accident after leaving the construсtion site where he was employed by the respondent, Contracting 8c Material Co. Both an arbitrator and the Industrial Commission found in favor of the respondent, and the circuit court of Cook County confirmed the decision. The only issue is whether the Commission’s decision that the claimant’s injury had not arisen out of and in the course of his employment by respondent was contrary to the manifest weight of the evidence. We think it was not. The facts are not in dispute, but the inferences to be drawn from them are.
The claimant was employed by the respondent as a timеkeeper, and lived in El Paso, about 113 miles from the Rockford area, where respondent was constructing stеel towers and lines to carry electrical current. His duties required him to be at the construction site daily to mаke out progress reports, answer the phone, order parts and do the payroll. While on the job during the workweek, he stayed at a motel, but traveled home each weekend. On Wednesday, September 3, 1975, the day before the injury, the claimant, apparently with the knowledge of respondent’s job superintendent, returned to El Pаso after work “because it was a pretty day[,] *** I had got off early, and had some things I needed to take care of.” On Thursday, September 4, the claimant arose at 4 a.m., returned to Rockford, and worked until 6:30 p.m. Because some of the workers were leaving for another construction project, an impromptu party devеloped inside and outside the trailer office. The group included a superintendent, general and job foremen, steward and workers. Although he did not customarily attend such parties, which respondent agrees were not unсommon, claimant stayed because previous parties resulted in disarranged records and papеrs. He was not instructed to stay, and he did no actual work. Between 6:30 and 11:30 p.m., claimant rolled dice, drank beer, lеft the party to buy beer, left again to buy pizza (which he did not get) and more beer, and ate a little food at thе trailer. (Between 4:30 and 6:30 p.m., claimant had two drinks of whiskey with the job superintendent.) At 11:30 p.m., claimant departed for his mоtel, 16 miles away, where he had a reservation. On the way, he decided he would be unable to drive the entire 16 miles because he was sleepy, and so he turned around to return to the site. Approximately four miles from the сonstruction site, he fell asleep, went off the road, awoke in the vehicle, got out and walked toward a man, whom he recognized as a police officer, who was approaching him. He suffered faciаl laceration, concussion and fracture of vertebrae.
“The Workmen’s Compensation Act was not intended to insure employees against all accidental injuries” but only those arising out of and occurring in the cоurse of employment. (Ace Pest Control, Inc. v. Industrial Com. (1965),
We cannot say that the Commission incorrectly found claimant’s conduct was unreasonable and unforeseeable by the employer, and that therefore its inferences are impermissibly drawn from the facts here. The Commission could have reasonably concluded the claimant lаcked sleep and might have drunk excessively; that the lack of sleep and the drinking were unreasonable and unforeseeable on a working day (Thursday); that claimant’s attendance at the “party” was not expected (because it was not customary for him) and therefore unforeseeable because it occurrеd on a working day and developed in an admittedly impromptu fashion (cf. Givenrod-Lipe, Inc. v. Industrial Com. (1978),
For these reasons we affirm the judgment of the circuit court.
Judgment affirmed.
