Opinion by
Mr. Justice Bell,Crane and Dean sued Neal in separate actions of trespass to recover damages for personal injuries and property damage. Neal sued Crane and Dean in trespass to recover damages for personal injuries and property damage. All the cases were tried together.
Around two o’clock a.m. on March 20, 1954, Crane and Dean were each riding a motorcycle in a westerly direction on Route 358 and were approaching the Borough of Greenville. The night was dark and it was raining. The engine of Crane’s motorcycle stopped so Crane and Dean parked their motorcycles on the paved portion of the highway (because the berm was muddy) while they worked on Crane’s machine. While working on Crane’s machine Crane and Dean were struck by a westbound automobile driven by Neal. Neal testified he was driving approximately 40 miles an hour when he was temporarily blinded by the lights of an eastbound automobile. He slowed his car to about 35 miles an hour. As the eastbound car passed him he saw the motorcycles on the highway in front of him about 100 feet away. One of the motorcycles was parallel with the edge of the pavement; the other one was angled between it in such a, way as to occupy all but one foot of the westbound lane. The paved portion of the highway was approximately 22 feet wide. Neal attempted to turn to his left but the rear of his car swung around and slid sideways and struck both motorcycles. His car came to rest against a culvert on the south side of the road 30 or 40 feet from the point of collision. Neither Crane nor Dean saw Neal’s car until after it had struck them, nor did they see any eastbound traffic prior to the accident.
Crane and Dean testified that while their motorcycles were on the paved portion of the highway, Crane’s motorcycle was only a few inches from its north *331edge and Dean’s motorcycle was parked parallel with it so as to leave an unobstructed space of approximately 8 feet in the west bound lane. Crane-and Dean testified, we repeat, that they did not move their motorcycles off the paved portion of the highway because the berms were muddy, although there was a slag driveway in the immediate vicinity which after crossing a muddy berm was in good condition.
The Court below entered a nonsuit against Neal in his actions against Crane and against Dean. The jury returned a verdict in favor of Crane against Neal in the amount of $3,000, and in favor of Dean against Neal in the amount of $12,000, and from the judgments entered thereon Neal took these appeals.
The narrow but important question which Neal raises is whether a new trial should be granted in the suit of Crane against Neal and of Dean against Neal because of the alleged errors in the trial Judge’s charge on the subject of contributory negligence. The importance of the question of contributory negligence in these cases is obvious from the above recital of the pertinent facts. The trial Judge charged the jury that “the contributory negligence of a party . . . must be a prowimate cause* of the incident involved. . . the term, proximate cause, . . . means a moving - or efficient cause, without which the injury would not- have occurred. It is an act or an omission- which becomes., a proximate cause of an injury whenever such injury is the natural and probable consequence; .of the-act--or omission in question, and one which ought to have, been foreseen by a person of ordinary care and prudence in, the light of the attending circumstances. It need not have been the sole cause of the incident, but it .must have been a moving — an efficient, productive Cause of *332the incident. So when you consider the negligence of any party, or the possible contributory negligence of any party, it should have a bearing on your decision only if that act was a proximate cause of the accident ” The trial Judge never mentioned that if plaintiffs’ negligence contributed in any degree to the accident it would bar their claims.
Defendant took not only a general exception to the charge of the Court but “specifically excepts to the Court’s definition of contributory negligence and the statement as to the necessity that it be the proximate cause of the accident”, and also an exception to the Court’s failure to sufficiently explain the duties of a person stopping on the highway. President Judge Rogers, speaking for the Court, held that the instructions were correct. Judge McKay differed with President Judge Rogers and correctly set forth the definition of contributory negligence. However, he found that no error was committed because the negligent act of parking committed by Crane and Dean was covered by a statute.
Courts must be careful not to confuse or equate contributory negligence with proximate cause.** The trial Judge committed reversible error in charging the jury that negligence on the part of Crane and Dean would not bar their recovery unless it was a proximate cause of the accident. Although broader language may be found in a few cases, “There is not the slightest doubt [under the law of Pennsylvania] that a plaintiff is guilty of contributory • negligence and cannot' re *333cover if his negligence contributed in any degree,* however slight, to the injury: Grimes v. Yellow Cab Co., 344 Pa. 298, 304, 25 A. 2d 294; McFadden v. Pennzoil Co., 341 Pa. 433, 436, 19 A. 2d 370; Robinson v. American Ice Co., 292 Pa. 366, 369, 141 A. 244; Goff v. College Hill Borough, 299 Pa. 343, 347, 149 A. 477.”: McDonald v. Ferrebee, 366 Pa. 543, 546, 79 A. 2d 232.
This test was adopted a century ago and it has. been iterated and reiterated ever since: see inter alia cases hereinabove cited and Creed v. Pa. R. R. Co., 86 Pa. 139; Monongahela City v. Fischer, 111 Pa. 9, 2 A. 87; Oil City Fuel Supply Co. v. Boundy, 122 Pa. 449, 15 A. 865; Weir v. Haverford Electric Light Co., 221 Pa. 611, 70 A. 874; Goldschmidt v. Schumann, 304 Pa. 172, 176, 155 A. 297; Kasanovich v. George, 348 Pa. 199, 34 A. 2d 523. As recently as Ulmer v. Hamilton, 383 Pa. 398, 403, 119 A. 2d 266, Mr. Justice Musmanno said, quoting from Goldschmidt v. Schumann, 304 Pa., supra: “ ‘The test for contributory negligence is whether the act [alleged as] constituting the negligence contributed in any degree to the production of the injury. . . .'"**
*334Where the question is whether defendant was guilty of negligence, the law is well and clearly established that “Plaintiff has the two-fold burden of proving that the defendant was negligent and that his negligence was the proximate cause of the accident.”: Malloy v. Pa. R. R. Co., 387 Pa. 408, 413, 128 A. 2d 40; Finnin v. Neubert, 378 Pa. 40, 43, 105 A. 2d 77; Brusis v. Henkels, 376 Pa. 226 228, 229, 102 A. 2d 146; Lanni v. Pa. R. R. Co., 371 Pa. 106, 109, 88 A. 2d 887; Gayne v. Philip Carey Mfg. Co., 385 Pa. 618, 621, 123 A. 2d 432; Helm v. So. Penn Oil Co., 382 Pa. 437, 441, 114 A. 2d 909; Freund v. Hyman, 377 Pa. 35, 37, 103 A. 2d 658; Parker v. McCrory Stores Corp., 376 Pa. 122, 124, 101 A. 2d 377; Thompson v. Gorman, 366 Pa. 242, 246, 77 A. 2d 413.
The marked difference between the legal standard for negligence and the legal standard for contributory negligence was -clearly pointed out and delineated by President Judge Keller in Cardarelli v. Simon, 149 Pa. Superior Ct. 364, 371, 27 A. 2d 250: “To recover a verdict against a defendant because of his negligence the jury must find that the alleged negligence was the proximate cause of the injury; but as respects a plaintiff, suing another for damages alleged to have been caused by the latter’s negligence, the rule in Pennsylvania, is. that he cannot recover if his own negligence contributed in any degree to the accident and injury.”*
The fundamental error in the Judge’s charge on the crucial subject of contributory negligence was not *335cured by the fact that the alleged negligent acts of Crane and Dean may possibly have violated Art. X, Sec. 1019 of The Vehicle Code of May 1, 1929, P. L. 905, 75 PS 611, relating to parking on an improved portion of a highway.
Plaintiffs contend that they could be guilty of contributory negligence only if their act in stopping on the highway specifically violated The Vehicle Code and then only if that stopping was the proximate cause of the accident. Under the evidence in this case that is not a correct statement.
It is a sound proposition of law that “Violation of a statute, constituting negligence per se, is nevertheless not a ground of liability, nor does it support a charge of contributory negligence, unless it is the proximate and efficient cause of an accident which is of the type the legislative enactment was designed to prevent [citing eases]”: Shakley v. Lee, 368 Pa. 476, 478, 84 A. 2d 322. However, what appellees and the Court below overlook is that defendant Neal relied not only upon The Vehicle Code, but more importantly upon the common law principles of contributory negligence. Thus, under the evidence in the instant case, the jury could properly have found that Crane and Dean in parking their motorcycles so as to occupy and block all but one foot of the westbound lane were guilty of contributory negligence irrespective and independent of the provisions of The Vehicle Code, and the jury should have been so charged.
A new trial must be granted because of reversible errors in the charge of the Court.
The Judgment in the case of Crane v. Neal and the Judgment in the case of Dean v. Neal are reversed and a new trial is granted in each cáse.
Italics throughout, ours.
One trial of multiple trespass suits involving claims and counterclaims of drivers and passengers arising out of the same accident often produce confusing as well as conflicting factual and legal questions which perplex and vex juries and Courts alike, and make a charge Very difficult.
Although many attempts have been made to change the definition of contributory negligence, and more recently to entirely eliminate contributory negligence as a bar to recovery and to substitute comparative negligence, Pennsylvania has rejected all such attempts.
In Oil City Fuel Supply Co. v. Bounty, 122 Pa. 449, 463, 15 A. 865, the Court held that a charge was erroneous which required that the negligence of plaintiff should contribute materially and essentially to the injury, and said: “The rule is that any degree of negligence on the part of the plaintiff, contributing to the injury, destroys his right to recover.” In Monongahela City v. Fischer, 111 Pa. 9, 2 A. 87, (and in Mattimore v. City of Erie, 144 Pa. 14, 22 A. 817), we held that the trial Court erred in telling the jury that the plaintiff could not recover if he was guilty of any negligence which contributed materially to the accident. The Court said (page 14) : “the doctrine of this Court has always been that if the neg*334ligence of the party contributed in any degree to the injury he cannot recover.”.
The Court reiterated this in Commonwealth v. Amecca, 160 Pa. Superior Ct. 257, 262, 50 A. 2d 725: “In legal parlance, contributory negligence. consists of negligence of the injured party which contributes in the slightest degree to his harm.”
