This appeal raises the question of whether plaintiff-appellant was prejudiced by the lower courts’ failure to apply the concept of comparative negligence to the instant facts.
R.C. 2315.19(A)(1) provides in pertinent part:
“In negligence actions, the contributory negligence of a person does not bar the person or his legal representative from recovering damages that have directly and proximately resulted from the negligence of one or more other persons, if the contributory negligence of the person bringing the action was no greater than the combined negligence of all other persons from whom recovery is sought. However, any damages recoverable by the person bringing the action shall be diminished by an amount that is proportionately equal to his percentage of negligence * *
The effective date of the above statute is June 20, 1980. The accident at bar occurred on January 22,1980. However, this court has held that the principle of comparative negligence as defined in R.C. 2315.19 shall apply to all negligence actions tried after June 20, 1980 regardless of when the cause of action arose. Wilfong v. Batdorf (1983), 6 Ohio St. 3d 100, paragraph three of the syllabus. The trial court entered summary judgment in favor of all defendants on February 22, 1983. Thus, although Wilfong, supra, had not yet been announced, R.C. 2315.19 applies to the instant cause, and it must be determined whether the facts herein raise an issue of negligence on the part of defendants, thereby warranting a remand for the determination of their respective degrees of negligence compared to that of plaintiff.
It should first be noted that we accept the ruling of the courts below to the effect that plaintiff was in fact negligent per se for failing to maintain the assured clear distance ahead. See Tomlinson v. Cincinnati (1983), 4 Ohio St. 3d 66, 69. The record indicates that plaintiff was aware he was gaining on the vehicles in front of him before he realized there was an accident and before he applied his brakes. Plaintiff argues that the “sudden emergency” exception should apply here, excusing him from compliance with the assured-clear-distance-ahead requirement. This is incorrect. This *54exception states that a driver does not violate the statute where the assured clear distance ahead is, without his fault, suddenly cut down or lessened by the entrance into his path of an obstruction which renders him unable, in the exercise of reasonable care, to avoid a collision. Erdman v. Mestrovich (1951), 155 Ohio St. 85 [44 O.O. 97], paragraph two of the syllabus. This case clearly does not involve the intrusion of an obstacle with a degree of suddenness which would render plaintiff incapable of avoiding a collision. Nor do weather conditions which result in slippery road surfaces excuse compliance. Ventress v. Frambes (1964), 176 Ohio St. 337 [27 O.O.2d 278], paragraph one of the syllabus. Finally, there is no question but that the tractor-trailer with which plaintiff collided was “reasonably discernible” to him, since he testified that he actually saw it before he applied his brakes. Thus, he cannot claim exemption from the statute under the rule that R.C. 4511.21 does not apply where the object was not reasonably discernible to the driver. See McFadden v. Elmer C. Breuer Transp. Co. (1952), 156 Ohio St. 430 [46 O.O. 354], paragraph one of the syllabus.
Having concluded that plaintiff was indeed contributorily negligent as a matter of law, we now turn to a determination as to whether the evidence adduced below raises a question of negligence on the part of any of the defendants. If we so find, it follows that summary judgment was inappropriate given the effect of R.C. 2315.19.
Upon an examination of the record, we conclude that no evidence was presented which would reasonably support a finding of negligence on the part of defendants Blanchard and Allen. The record demonstrates that they were both able to stop their vehicles in time to avoid a collision. They had no time to move off the road out of the way of traffic before their vehicles were struck by Scherzer. There was no evidence whatsoever that any course of action reasonably available to Blanchard and Allen could have prevented the accident in question, nor that their conduct had any causal connection with plaintiff’s injury or his wife’s death. Thus, reasonable minds could only conclude that defendants Blanchard and Allen were not negligent, nor were their actions a proximate cause of the collision. Summary judgment in their favor was therefore appropriate. See Civ. R. 56(C).
As to defendants Scherzer and Indianhead Truck Line, Inc., Scherzer’s failure to stop within the assured clear distance ahead was negligence per se as a violation of R.C. 4511.21.
At this juncture it should be noted that the negligence of Clifford Shinaver, as driver of the pick-up truck, may not be imputed to his passenger, the decedent Dorothy Shinaver. Parrish v. Walsh (1982), 69 Ohio St. 2d 11 [23 O.O.3d 7]; Hocking Valley Ry. Co. v. Wykle (1930), 122 Ohio St. 391; Rehklau v. Bourne (1928), 118 Ohio St. 494; 39 Ohio Jurisprudence 2d (1959) 676-677, Negligence, Section 114. The complaint contains operative facts supporting three separate claims for relief, name*55ly: (1) plaintiff’s claim for his own personal injuries; (2) plaintiff’s claim for personal injuries, pain and suffering and medical expenses for Dorothy Shinaver prior to her death which survived to the plaintiff as executor; and (3) plaintiffs claim as executor of the estate of Dorothy Shinaver for damages for wrongful death brought pursuant to R.C. 2125.01 for the benefit of her beneficiaries, namely, her husband and children.
Where the plaintiff driver is travelling immediately behind the defendant driver, and both parties are negligent per se for failing to maintain the assured clear distance ahead in violation of R.C. 4511.21, the question of whether the negligence of either party was the proximate cause of the ensuing collision, in which the plaintiff driver sustained personal injuries, is for jury determination. The defendant driver immediately ahead of plaintiff has no right to summary judgment. Cascone v. Herb Kay Co. (1983), 6 Ohio St. 3d 155; Mudrich v. Standard Oil Co. (1950), 153 Ohio St. 31 [41 O.O. 117], paragraph two of the syllabus; 39 Ohio Jurisprudence 2d (1959) 525-530, Negligence, Sections'26-28; Jolley v. Martin Bros. Box Co. (1950), 89 Ohio App. 372 [46 O.O. 157], paragraph three of the syllabus; Smith v. Rawlins (1960), 253 N.C. 67, 116 S.E. 2d 184; Annotation (1962), 85 A.L.R. 2d 613, 628, Section 8. Thus, the foregoing legal principle applies to plaintiff’s first claim for relief for his own personal injuries.
The contributory negligence of plaintiff is not relevant to the second claim for relief whereby recovery is sought for the personal injuries, pain and suffering of decedent Dorothy Shinaver, and her own medical expenses prior to her death, a cause of action which survived to the plaintiff as executor. This second claim for relief is unaffected by plaintiff’s contributory negligence because his negligence is not imputed to his passenger. Parrish v. Walsh, supra. Under the general survival statute, R.C. 2305.21, a victim’s right of action for personal injuries survives and passes to her personal representative, and may be instituted for the benefit of the estate, notwithstanding that death resulted from injuries for which an action could also be maintained under the Wrongful Death Act, R.C. 2125.01 et seq. Wellston Iron Furnace Co. v. Rinehart (1923), 108 Ohio St. 117, paragraph two of the syllabus; 1 Ohio Jurisprudence 3d (1977) 578, Actions, Section 156. Under R.C. 2305.21, an administrator or executor may maintain an action in the same manner in which decedent could have maintained such action if she had survived. Hillard v. Western & Southern Life Ins. Co. (1941), 68 Ohio App. 426 [23 O.O. 133].
With regard to the third claim for relief, namely, the wrongful death action for Dorothy Shinaver under R.C. 2125.01, the contributory negligence of the plaintiff is available as a defense against those beneficiaries whose negligence contributed to the death of the deceased, but not against those who were free from negligence. The negligence of one beneficiary is not imputed to the other beneficiary so as to bar recovery by the latter. Cleveland, C.C. & St. Louis Ry. Co. v. Grambo (1921), 103 Ohio St. 471; 30 Ohio Jurisprudence 3d (1981) 323, Death, Sec*56tion 73. The contributory negligence of plaintiff Shinaver is a partial defense only as to his share of the right to a recovery of damages, but does not constitute a defense to the right of his children to recover damages. This issue of the contributory negligence of the plaintiff in the wrongful death action (and the negligence of defendants Scherzer and Indianhead Truck Line, Inc., as being the proximate cause of the death) must be submitted to the jury pursuant to the comparative negligence provisions of R.C. 2315.19(A)(1).
The judgment of the court of appeals is hereby reversed and the cause is remanded to the trial court for further proceedings consistent with this opinion.
Judgment reversed and cause remanded.
