These appeals are from judgments in a personal injury action (4th Civil No. 7786) and a wrongful death action (4th Civil No. 7787) arising out of a two-car automobile collision. The accident occurred about 8:15 p.m. on August 21, 1961, at the intersection of Central Avenue and Francis Street in the unincorporated territory of San Bernardino County, between a 1949 Chrysler operated by James Sehauf, a minor, west-bound on Francis Street, and a 1957 Chevrolet northbound on Central Avenue. Francis is a two-lane street and Central is a four-lane through street, all streets intersecting Central in the area, including Francis, being controlled by stop signs. The Chrysler failed to stop before entering the intersection.
Robert Sehauf (the driver’s brother) and Robert and Thomas McClain (brothers), all minors, were occupants of the Chrysler. They, and James Sehauf, the driver, all suffered injuries of varying degrees. Robert McClain subsequently died as result of the injuries he suffered. The Sehauf brothers, James and Robert, through their father, Simon Sehauf, as guardian ad litem, filed a personal injury action against the driver of the Chevrolet, his employer and owner of the Chevrolet, the County of San Bernardino and Southern California Edison Company (hereinafter referred to as Edison). Mr. and Mrs. McClain filed a separate wrongful death action against the same defendants for the death of their son, Robert. The two cases were consolidated for trial.
The county and Edison were joined as defendants on the theory that they negligently maintained a hazardous condition at the intersection in that the visibility of the stop sign (installed by the county in 1940) controlling west-bound traffic on Francis was obstructed by an Edison power pole (installed by Edison in 1937 under a county franchise). The stop sign was located 8 feet north of the north line of Francis and 36 feet east of the east line of Central. The power pole *454 was located on the north side of Francis about 16 feet east of the stop sign. At the time of the accident, the pole and the stop sign had not been moved from their original positions.
After the commencement of the trial, the county reached a settlement with plaintiffs in both actions and trial proceeded to conclusion against the remaining defendants. The jury returned the following verdicts: (1) in favor of the driver and owner of the Chevrolet against all plaintiffs; (2) in favor of Edison against James Schauf; (3) in favor of Robert Schauf against Edison; and (4) in favor of the McClains against Edison.
James Schauf appeals from the judgment in favor of Edison. Edison appeals from the judgment in favor of Robert Schauf and the McClains.
Pursuant to stipulation of the parties, the appeals have been consolidated for hearing and for disposition by a single opinion.
James Schauf Appeal
Plaintiff James Schauf seeks a reversal of the judgment in favor of defendant Edison on grounds that the court erred (1) in rejecting the testimony of his father, Simon Schauf, concerning observations he made at the scene of the accident about a week later, (2) in rejecting the testimony of his expert witness relating to the existence of a hazardous condition at the intersection, (3) in improperly instructing the jury by imposing on him the standard of care of an adult and (4) in improperly instructing the jury on the burden of establishing contributory negligence.
To show that the power pole obstructed the visibility of the stop sign as to west-bound traffic on Francis, plaintiffs sought to introduce the testimony of Simon Schauf respecting observations he made when he later visited the scene of the accident at night in an automobile driven by a friend. When asked what his observations were when he got out of the automobile at the intersection and looked at the stop sign he replied: “We stopped and looked it over and you can’t hardly see the sign until you get practically right up to it. ’ ’ This and similar answers were stricken. He was permitted to testify that “You could only see a couple or three of the letters” and that the pole looked like “. . . the regular telephone pole,” but was not permitted to state how the stop sign and pole appeared to him as he was riding west-bound on Francis toward the intersection.
*455
There was no error in the court’s ruling. Plaintiff urges that the witness was simply attempting to relate facts he observed concerning the relationship of the pole to the stop sign as he was traveling westerly on Francis which facts he was unable to convey to the jury except in an opinion or conclusionary form. The offered testimony, however, constituted evidence of an experiment conducted by Simon Schauf to prove that the visibility of the stop sign was obstructed by the pole and that the sign would not become visible in time to serve as a warning to west-bound traffic on Francis. Since experiments conducted outside the courtroom frequently present serious questions concerning similarity of conditions, accuracy of observations, and tendency to confuse rather than clarify issues, the admissibility of the results of such experiments rests in the sound discretion of the trial court whose ruling will be sustained in the absence of clear abuse of discretion.
(People
v.
Ely,
Plaintiff also maintains that certain testimony of his expert witness, Mr. Sex^ery, a research engineer, was erroneously rejected. Objections were sustained to questions seeking to elicit his opinion, based on his examination of photographs of the intersection and its environs, whether the intersection presented a maintenance hazard to west-bound traffic on Francis approaching the intersection. His testimony concerning the existence of a traffic engineering principle which he referred to as “expectancy" and described as a “principle *456 by which drivers are given proper cuing or advanced warning to situations which for their safety or guidance they are required to know” was stricken, and an objection was sustained to a hypothetical question as to whether, in his opinion, a normally alert driver west-bound on Francis at the time and place of the accident “had basis for expectancy of a stop sign as he approached Central”.
Although the fact that an expert’s opinion is on an ultimate issue of fact to be determined by the jury is not a ground for the exclusion
(Martindale
v.
City of Mt. View,
Plaintiff complains that the giving of BAJI No. 149, Revised, 1 without qualification, erroneously imposed on him, a minor, the duty of care of an adult; he argues that to prove contributory negligence, the defendant should have been required to prove that plaintiff failed to exercise the care required of a minor of his age, experience and capacity.
That issue was laid to rest by the Supreme Court during the pendency of this appeal in
Prichard
v.
Veterans Cab Co.
(Dec. 20,1965)
Plaintiff finally contends that BAJI No. 149 Revised relating to the presumption of negligence arising from a statutory violation erroneously imposed on plaintiff the burden of dispelling the presumption by a preponderance of the evidence. He maintains that a violation would raise only a rebut-table presumption of negligence which may be overcome by evidence sufficient to balance it. There was no error in the giving of the instruction. It correctly expresses the rule enunciated in
Alarid
v.
Vanier,
The judgment in favor of Edison and against plaintiff, James Schauf, is affirmed.
" Edison Appeal
Plaintiffs urge that Edison was liable because its power pole obscured the stop sign controlling west-bound traffic on Francis, that the existence of that condition constituted a traffic hazard, that despite Edison’s constructive knowledge of the dangerous condition, it negligently failed to take affirmative action to guard the traveling public against the danger.
Edison urges several grounds upon which it bases its contention that the judgments in favor of plaintiffs Robert Schauf (4th Civ. 7786) and the McClains (4th Civ. 7787) should be reversed .but, as we view it, the controlling issue is whether, under the undisputed facts, Edison had a legal duty to take affirmative steps to guard plaintiffs against the claimed hazard. The undisputed facts are that Edison installed the power pole in 1937 pursuant to a county franchise, the county installed the stop sign in 1940, and neither the pole nor the sign has been moved since its installation.
Except where the ultimate determination as to whether a duty exists turns on forseeability, its existence is initially a question of law, reviewable on appeal, even though reasonable minds may differ as to whether or not a duty should be imposed.
(Amaya
v.
Home Ice, Fuel & Supply Co.,
Edison contends that the law did not impose upon it the duty to take affirmative steps to correct the dangerous condition, if one existed. It argues that its duty with respect to the maintenance of the pole is limited to its obligations to the county under the terms of the franchise pursuant to which the pole was installed. Section 7 of the franchise ordinance provides: “When any of said poles or wires shall become an
*459
obstruction to the use of any of said streets or highways, or dangerous to the users thereof, said Board of Supervisors shall have the right to order said poles relocated or remodeled at the expense of the grantee of this franchise, its successors or assigns, to avoid such obstruction or danger.” From this premise, Edison argues that since there was no county demand to relocate, there was no breach of duty. It contends, moreover, that a breach of the franchise would only give rise to a cause of action in favor of the county and not one in favor of third persons, either under a third party beneficiary contract doctrine or as a common law tort. In support of its position, Edison relies upon
Stang
v.
City of Mill Valley,
It is unnecessary, however, to decide whether the failure to relocate the pole at the county’s request would have given rise to a cause of action in contract or tort in favor of plaintiffs for it is conceded that the county had never made such a request. Moreover, it is plaintiffs’ contention that Edison owed a duty to the public independent of the company’s obligations under the franchise.
The fact that a utility company may have lawfully
*460
installed a structure in a public right-of-way pursuant to a permit or a franchise does not excuse it from tort liability for injuries caused by the negligent exercise of the right and power to erect and maintain the structure.
(Gerberich
v.
Southern Cal. Edison Co., Ltd.,
It does not follow, however, that Edison had a duty to take affirmative action to correct the claimed hazard in this case. In all of the cases mentioned in the preceding paragraph, the pole or structure itself constituted the hazard, either as originally installed or under changed conditions. Por example, in
Alpine Telephone Corp.
v.
McCall, supra,
In our opinion, the county is the agency which created and maintained the unsafe condition—the relationship of the sign to the pole—by initially placing and thereafter maintaining the stop sign in such a position that its visibility was obscured by the preexisting power pole. The county’s action was tantamount to the installation and maintenance of a defective stop sign. In
Dudum
v.
City of San Mateo,
The court’s reasoning in
Dudum
v.
City of San Mateo, supra,
The question remains whether, by having constructive knowledge of the dangerous condition and the power to correct it by relocating its pole, Edison had a duty to take steps to guard motorists against the danger.
Ordinarily, in the absence of some special relationship, a person has no duty to take the affirmative steps to protect another from harm arising out of the unlawful conduct of a third person
(Richards
v.
Stanley, supra,
In a recent Oregon ease decided during the pendency of this appeal and involving facts which were apparently similar to those in the instant case, the Oregon Supreme Court held that, as a matter of law, there was no duty on a utility company to relocate a power pole which interfered with the visibility of a stop sign installed by the state long after the installation of the power pole.
(Ashland
v.
Pacific Power & Light Co.
(Sept. 23, 1964)
In our opinion, policy considerations, which this court should weigh in determining whether a common law duty should be judicially imposed
(Amaya
v.
Home Ice, Fuel & Supply Co., supra,
We conclude that Edison was not under a legal duty to take corrective action to eliminate the claimed traffic hazard.
Since we have determined that there was no legal duty on Edison to guard against the unsafe condition, there is no question of concurrent negligence or intervening causation;
(Richards
v.
Stanley, supra,
In view of the foregoing, it is unnecessary to consider other grounds of reversal argued by Edison.
The judgments in favor of Robert Schauf and the McClains are reversed and the trial court is directed to enter judgments in favor of Edison in each case.
McCabe, P. J., and Kerrigan, J., concurred.
A petition for a rehearing was denied August 2, 1966, and plaintiffs’ petition for a hearing by the Supreme Court was denied September 7,1966.
Notes
The court gave the following instruction: "If a party to this action violated Sections 22450(a) or 21802(a) of the Vehicle Code just read to you, a presumption arises that he was negligent. This presumption is not conclusive. It may be overcome by other evidence showing that under all the circumstances surrounding the event, the conduct in question was excusable or justifiable.
" To prove that a violation of a statute such as that charged in this case was excusable or justifiable so as to overcome the presumption of negligence, the evidence must support a finding that the person who violated the statute did what might reasonably be expected of a person of ordinary prudence who desired to comply with the law, acting under similar circumstances. ’ ’
In the absence of a possible error in the facts stated in. the opinion, it is not apparent how the obstruction of the stop sign described in the opinion would have any bearing upon the happening of the collision. The court assumed, however, that there was a causal connection between the obstruction of the stop sign described and the accident.
