While we are fully aware of the beneficent and salutary rule, to which this court scrupulously adheres in proper cases, that ordinarily questions of diligence and negligence, including proximate cause, are for the jury, we also recognize it to be the duty of the court to determine those questions in clear, palpable, and indisputable cases.
Evans
v.
Georgia Northern R. Co.,
78
Ga. App.
709, 712 (
“If the plaintiff by ordinary care could have avoided the consequences to himself caused by the defendant’s negligence, he is not entitled to recover.” Code § 105-603.
From the petition, and under an application of the foregoing rules of law, it is apparent that admitting the truth of all the allegations of negligence attributed to the defendant, the plaintiff’s son could have avoided the occurrence which resulted in his death by the exercise of ordinary care for his own safety after *355 he had, or in the exercise of ordinary care, should have, discovered the defendant’s alleged negligence.
The plaintiffs’ son is alleged to have been 20 years of age at the time of his death, and in the absence of an allegation to the contrary he will be presumed to have been mentally responsible, and to be as responsible as an adult is for his own safety
(Youngblood
v.
Henry C. Beck
Co., 93
Ga. App.
451, 454,
From all this the only reasonable conclusion to which we can come is that the plaintiffs’ son was the author of his own misfortune in ploughing headlong at an unabated speed into a clearly visible obstruction in the street, when in the exercise of ordinary prudence he could have avoided the obstruction by stopping his *357 vehicle or by turning aside to avoid striking it. Since under the rules of law stated above, the plaintiffs’ son, were he alive, could not recover, his parents, the plaintiffs, may not. Youngblood v. Henry C. Beck Co., 93 Ga. App. 451, 454. Accordingly, the trial court erred in overruling the defendant’s general demurrers to the petitions.
Judgments reversed.
