—Defendant was found guilty of driving a vehicle while under the influence of narcotics (§23105, Veh, Code). Motion for a new trial was denied and the court ordered a petition to be filed in department 95 under section 3051, Welfare and Institutions Code. Upon his return for further criminal proceedings, defendant was sentenced to the state prison, the term to run concurrently with any prior ineompleted sentence. He appeals from the judgment.
Officer Key, a narcotics officer, had information from Officer Marinelli, Glendale Police Department that a person named Macknic would be around 5th and Burlington in Los Angeles between 10:30 and 10:45 a.m.; possibly a narcotic buy could be made from him; Macknic would be driving a 1954 two-tone white over blue Chevrolet; and he was wanted for parole violation on a narcotics offense. Officer Key and other law enforcement officers, and State Narcotic Agent Feldman in a separate vehicle, watched the location and around 10 :45 a.m. saw defendant driving the Chevrolet. When he stopped for a red signal, Agent Feldman got out of his car and approached defendant on the driver’s side; as he neared the Chevrolet defendant started up the car, turned it to the left in the direction of the agent, forcing him to jump out of the way, and drove away. In his car Officer Key overtook defendant, pulled alongside of him, identified himself and ordered him to stop; defendant complied and upon being told to do so, got out of the car. Officer Key asked him for his identification; he said his name was Vernon Macknic. Asked if he was on parole defendant said he was, was in violation and “had been running for about nine months.” It was stipulated that Officer Key is an expert in determining whether a person is under the influence of narcotics. The officer “observed that defend *372 ant was perspiring profusely, that his eyes were pinpoint, and that he lacked coordination in that he was slow to move and staggered,” and since defendant was wearing a short-sleeved shirt “also observed numerous marking on his arms, which appeared to be needle marks ”; he then formed the opinion that defendant was under the influence of narcotics and arrested him for parole violation and for driving a vehicle while under the influence of narcotics. After his arrest defendant was advised of his constitutional rights and transported to the station where a further examination of the inner portion of his left forearm revealed several tracks with scabs and marks indicating hypodermic injections, and on the back portion, an area with approximately fifteen scabs and marks varying in age from one to twenty-one days, one scab appearing to be recent or fresh. An examination of his eyes in the light accommodation test showed that they “went from a maximum of 3.5 millimeters to 3 millimeters, with a very sluggish reaction to the light.” As a result of these observations he formed the opinion that defendant was under the influence of narcotics.
Defendant testified that at the time of his arrest he was not under the influence of narcotics, had no trouble controlling his vehicle, had not used narcotics that day, was not addicted to heroin at that time and had his last “fix” a day and a half before arrest.
On his own testimony and that of Officer Key that he was driving at a normal speed and did not appear to be violating any vehicle laws before stopping at the red signal, appellant asserts that there was no probable cause either for Agent Feldman to approach him or for Officer Key to arrest him. There is nothing improper about an officer stopping a motorist or a pedestrian on the streets for questioning when to a reasonable person such a course of conduct appears necessary to the discharge of his duty

Equating his “right” to a Nalline test when arrested with his rights “under the

However, the absence of a Nalline test has no effect on the conviction because the testimony of Officer Key was sufficient

to establish defendant’s condition. “While it is true that no blood sample or other mechanical or chemical test was taken or made of the defendant to establish that his condition was the effect of the use of narcotics, this is not the only type of evidence which will sustain the finding of 'under the influence of a narcotic drug.’ . . . The detailed testimony of the observable physical and mental reactive state of the defendant was testified to by police officers experienced in observing such details. The opinion as to the cause of defendant’s condition, if admissible as expert opinion, was sufficient to prove the fact.”

Notes
At the preliminary hearing on voir dire examination defense counsel sought to examine Officer Key relative to the reliability of Officer Marinelli. Upon objection the judge said: “The Court will, at least at this stage, permit the mere fact that the informant was a police officer from another jurisdiction to be sufficient reliability upon which this officer could act further.” While the cause was submitted on the transcript of the testimony taken at the preliminary hearing, at the trial there was ample opportunity to explore the subject. Officer Key was further examined and defendant took the stand. At no time on the trial level did defense counsel raise the issue by objection or otherwise, make mention of the point, seek to examine Officer Key on the subject of Officer Marinelli’s “reliability” or argue the matter to the trial judge. The court’s ruling on the preliminary hearing was proper. In light of the record we deem to be unnecessary further discussion of appellant’s present claim that his inquiry in the area of the reliability of Officer Marinelli as an informer was curtailed.
