937 (42 S. E. 234); Pullman Palace Car Co. v. Martin, 92 Ga. 161 (18 S. E. 364)." Harvey v. Zell, 87 Ga. App. 280, 284 (d) (73 S. E. 2d 605). The petition in this case being a suit against two defendants alleged to have been joint tortfeasors, alleges that the plaintiff's husband was killed as the result of the concurring negligence of the two defendants; that the defendant Drake was the host driver of the automobile in which the plaintiff's husband was riding; that he was negligent in driving his automobile at 90 miles per hour in the night time; in operating it across the white center line and on the left-hand side of the road; in failing to keep a lookout for approaching cars; and that such negligence was gross negligence which proximately caused him to collide with the truck of the defendant trucking company, the driver of which was also negligent in specified particulars, which collision inflicted injuries resulting in the death of the plaintiff's husband. Under the rules of law set out above, the petition stated a cause of action against the defendant Drake and the trial court did not err in overruling his general demurrer.
