¶1The Commonwealth brings the instant appeal from the trial court’s order granting of appellee’s demurrer to the charge of homicide by vehicle, Motor Vehicle Code, 75 Pa.C.S. § 3732 (1977).
¶2Section 3732 of the Motor Vehicle Code provides:
Any person who unintentionally causes the death of another person while engaged in the violation of any law of this Commonwealth or municipal ordinance applying to the operation or use of a vehicle or to the regulation of traffic is guilty of homicide by vehicle, a misdemeanor of the first degree, when the violation is the cause of death.
¶3The Commonwealth argues and the Dissent agrees that the words of this provision are precise and unambiguous. From this the Commonwealth further reasons that this statute unequivocally evidences a legislative intent to impose the severe penal sanctions of up to five years imprisonment
¶5Constitutional Challenges to Section 3732
¶6On this cross-appeal from the lower court’s refusal to hold section 3732 unconstitutional, the appellee, Ms. Barone, advances three contentions. Ms. Barone urges that section 3732 runs afoul of the Due Process Clause of the United States Constitution inasmuch as it is vague and overbroad, omits to require as an essential element of the offense some degree of “fault” or mens rea, and denies the accused the right to have all charges disposed of at the magistrates level. This latter invalidity is said to stem from the procedure made applicable to a section 3732 prosecution under our Supreme Court’s decision in Commonwealth v. Campana.
¶7a.
¶8In evaluating Ms. Barone’s assertions, we are initially guided by certain well settled principles of appellate review of constitutional questions. Thus, it is beyond cavil that this court will not sua sponte raise constitutional questions which have not been framed by the parties. E. g., Wiegand v. Wiegand, 226 Pa.Super. 278, 310 A.2d 426, rev’d 461 Pa. 482, 337 A.2d 256 (1975). Nor should we address constitutional issues unnecessarily
¶9On September 14,1977, Ms. Barone was accorded a preliminary arraignment which was followed by a preliminary hearing on September 28, 1977. Subsequently, on October 17, 1977, Ms. Barone filed both a motion to quash the complaint on non-constitutional grounds and a separate petition seeking a declaration of the unconstitutionality of section 3732. The motion to quash omitted all reference to the alleged unconstitutionality of section 3732. The petition alleged only a deprivation of due process by virtue of the procedure mandated by Commonwealth v. Campana. The alternative constitutional attacks on the two theories of vagueness and overbreadth and lack of mens rea were not filed until January 10, 1978, and April 24, 1978, respectively. During the period between these latter two petitions, the Honorable Robert W. Tredinnick on April 7, 1978, dismissed Ms. Barone’s constitutional forays. Presumably, this order only addressed the alleged denial of procedural due process and the vagueness and overbreadth contentions.
¶10To complicate matters, in its answer to Ms. Barone’s petition of April 24, 1978, the Commonwealth maintained that Ms. Barone had waived any grounds for relief bottomed upon the unconstitutionality of the statute which had not been raised in the original petition. See Record at 23a. Later, at oral argument on this petition, the Commonwealth reasserted its objection. See Record at 38a and 39a. The lower court apparently agreed with the Commonwealth’s analysis and refused to address the merits of the last petition. See Record at 40a.
¶11*288Pennsylvania Rule of Criminal Procedure 304 (eff. version January 1, 1965)
“(a) All pre-trial applications for relief shall be in writing and presented under the name and style of application.
(e) All grounds for the relief demanded shall be stated in the application and failure to state a ground shall constitute a waiver thereof.
¶12In principle, this Rule initially allows the filing of separate applications for relief, that is, a motion to quash and a petition to declare unconstitutional,
¶13b.
¶14Thus, Ms. Barone’s sole constitutional argument rests on her claim she was denied due process of law because “she was not afforded the opportunity to have all charges quickly disposed of at the magistrates level.” More specifically, Ms. Barone boldly asserts, with no citation of authority, that where, as here, a summary offense is an essential element of the charged indictable offense, an accused is absolutely entitled to a finding of guilty or not guilty on the summary offense. Insofar as the Dissenting opinion finds this hypothesis to be devoid of merit, we agree.
¶15II.
¶16Turning to the merits of the Commonwealth’s appeal from the lower tribunal’s granting of Ms. Barone’s demurrer,
¶17Logically, in adjudging whether the culpability requirements of section 302(a) are applicable to any of the material elements of a section 3732 offense, analysis should commence with section 305 which generally governs the scope of section 302(a). Section 305 provides in pertinent part:
“(a) The requirements of culpability prescribed by . Section 302 of this title ... do not apply to: (2) offenses defined by statutes other than this title, insofar as a legislative purpose to impose absolute liability for such offenses or with respect to any material element thereof plainly appears.
¶18This section of the Crimes Code is essentially identical to the parallel provision of the Model Penal Code, § 205(l)(b) (1962). The Comments to this proviso expressly observe “[t]hat this section makes a frontal attack on absolute or strict liability in penal law, whenever the offense carries a possibility of sentence of imprisonment.” Model Penal Code, § 2.05, Comment 1 (Tent. Draft No. 4, 1955) (emphasis added). Implementation of this strong common law tradition against strict penal responsibility
¶19The above approach, however, is not novel to Pennsylvania appellate courts. Our courts, as the Dissent correctly points out, have customarily adhered to the following principles of statutory construction 1) When the legislature employs language which is plain and unambiguous, there is no longer justification to resort to the rules of statutory construction;
¶20I begin with the words that are used to delineate the offense in this case. E. g., In re North Am. Rayon Corp., 383 Pa. 428, 430, 119 A.2d 205, 207 (1956). See Commonwealth ex rel. Cerminara v. Cerminara, 239 Pa.Super. 111, 115-117, 362 A.2d 1011, 1014-15 (1976). The critical word in the title is “homicide.” In this Commonwealth, our court has uniformly interpreted enactments which carry this solemn title as requiring that the voluntary act which caused *292the death be done with some degree of fault, that is, intentionally, knowingly, recklessly, or more recently negligently. The legislature has further provided that the “homicide” which is punishable is that which is caused “unintentionally” while operating a motor vehicle. Taken in context, “unintentional”
¶21a.
¶22Where, as here, we determine that the words or phrases of an act are equivocal or ambiguous, legislative intention may be ascertained by examining the circumstances which surrounded enactment, the harm sought to be regulated and prevented, the object sought to be obtained, the consequences of any particular construction, and the germane legislative history. 1 Pa.C.S. § 1921(c)(1)-(7) (Supp.1978-79). E. g., Casey v. Pa. State Univ., 463 Pa. 606, 345 A.2d 695 (1975); Pa. Labor Relations Bd. v. State College Area School Dist., 461 Pa. 494, 337 A.2d 262 (1975); Commonwealth ex rel. Reed v. Maroney, 194 Pa.Super. 514, *294168 A.2d 800, cert. denied, 368 U.S. 907, 82 S.Ct. 187, 7 L.Ed.2d 100 (1961).
¶23Circumstances Surrounding Enactment
¶24In 1966 Congress passed the Highway Safety Act of 1966, 23 U.S.C. § 401et seq. (1970). This act authorized the United States Secretary of Transportation to adopt standards for all state highway safety programs. Pursuant to this mandate, the Secretary promulgated a standard on “Codes and Laws.” This standard required all states to conduct comparative traffic law studies which would eventually be used to yield state legislation providing for uniform rules of the road within each state and the nation. Variations in state law were to be detected by comparing the states’ current laws with the specimen provisions contained in the then effective version of the Uniform Vehicle Code § 11-101 et seq. (rev. ed. 1962).
¶25The initial report was published in January of 1973. The report revealed that Pennsylvania’s traffic laws were among the most outdated and non-uniform in the United States. Employing the provisions of the U.V.C. as the norm, the study ranked Pennsylvania 49 out of 51 jurisdictions. See United States Department of Transportation, National Committee on Uniform Traffic Laws and Ordinances, Contemporary Overview of Traffic Law Uniformity in the United States 9 (1973). Alarmed by the consequences of failing to comply with the standard,
¶26Harm to be remedied and object sought to be obtained.
¶27As alluded to above, the primary legislative intent in revising the rules of the road chapter of the Motor Vehicle Code was to eliminate highway accidents and delays which were due in large degree to both Pennsylvania and non-resident operators proceeding on the highways on the basis of different and obsolete rules of driver conduct. See Morris & Packel, supra, at 1. Regarding the legislation sub judice, the prime object sought to be obtained was no different than that which provoked the modernization of all the rules of the road, i. e., uniformity. Not surprisingly, therefore, the legislature turned to the U.V.C. as a model for its homicide by vehicle provision. Id. at 186. Of course, as the Dissent observes, there were additional possible reasons why the legislature chose to enact a distinct offense governing vehicular homicides. Foremost among these other reasons might have been a desire to reduce the fatalities on our roadways, and a corresponding recognition of the limited utility of our involuntary manslaughter statute in coping with the problem. Id. However, both of these weighty concerns are not jeopardized by reading the subject statute as not dispensing with the requirement that the harm causing violation must nevertheless be culpable. More directly, to credit the legislature with an intent to deter life endangering conduct on our roadways is to acknowledge that in order for punish*296ment to be efficacious and just under his provision, it must be predicated upon the accused’s awareness of the factors which made his conduct criminal. Thus, conviction, punishment, and sentence may well provide inadvertent violators with an additional incentive to take more care in both evaluating the risks they consciously create and those which they unreasonably fail to perceive. In either case, however, the assumption which underlies the punishment is that the actor ignored the operative factors in creating a risk of harm to others. Confronted with imprisonment, the violator may indeed think twice prior to speeding through a densely populated neighborhood. On the other hand, to suggest as the Dissent does that our legislature intentionally chose to disregard the social utility of the driver’s conduct is to impute to the legislature a harshness and shortsightedness which we cannot. While there is always some risk associated with driving an auto, we do not think that the legislature in its collective wisdom intended to abrogate the possibility of a finding that the risk taken was reasonable under the particular circumstances.
¶28Other Statutes
¶29Nor do the supposed shortcomings of our involuntary manslaughter statute alone justify a determination that the vehicular homicide proviso was intended to create strict criminal responsibility. This Court has recently ruled that the convenience of investigation and prosecution is not the polestar in ascertaining what the essential elements of an offense are or what degree of culpability must accompany them. E. g., Commonwealth v. Hughes, 268 Pa.Super. 536, 408 A.2d 1132; Commonwealth v. Sojourner, 268 Pa.Super. 488, 408 A.2d 1108 (1979). We concede that the history of this proviso confirms a legislative judgment that a distinct offense was needed due to the reluctance of juries to convict for involuntary manslaughter in fatal traffic accident cases, see Morris & Packel, supra, at 186; however, we dispute that this history supports the further proposition that as a result of this difficulty the legislature threw in the proverbial *297towel and deemed it essential to punish every violator no matter how reasonable his conduct. Faced with this difficulty, we reason that the legislature intended to adopt an intermediate response.
¶30It is true that under the present involuntary manslaughter statute a negligent operator completely escapes any criminal punishment unless the violation which precipitated death was perpetrated “in a reckless or grossly negligent manner.” Crimes Code, 18 Pa.C.S. § 2504 (1973).
¶31IV.
¶32The only remaining question is whether the trial court properly sustained Ms. Barone’s demurrer to the charge. In reviewing the propriety of this action, “the test to be applied ... is whether the evidence of record and the inferences reasonably drawn therefrom would support a guilty verdict, and in making our determination we must read the evidence in the light most favorable to the Commonwealth.” Commonwealth v. Trainor, 252 Pa.Super. 332, 334, 381 A.2d 944, 945 (1977) (quoting with approval from Commonwealth v. Bey, 221 Pa.Super. 405, 406, 292 A.2d 519, 520 (1976). Instantly, the focus of our inquiry is whether the Commonwealth’s evidence was sufficient to prove beyond a reasonable doubt that Ms. Barone’s conduct *299amounted to “a gross deviation from the standard of care that a reasonable person would observe in [her] situation.” Crimes Code, 18 Pa.C.S. § 302(b)(4) (1973).
¶33Thus viewed, the Commonwealth adduced the following. On September 14,1977, Ms. Barone was on route to her place of employment in a two-door, brown Toyota. At approximately 8:00 a. m. she arrived at the intersection of Bethel Grant Road and Morris Road in Upper Gwynedd Township, Montgomery County. The weather was clear and the roadways dry. As she approached the intersection, she observed a stop sign and initially obeyed its command to come to a complete stop. As is often the case at a major thoroughfare during this time of day, traffic was heavy. She observed this traffic for approximately two to three minutes waiting for an opportunity to safely cross the intersection. Subsequently, Ms. Barone apparently either failed to look to her right or misjudged the distance and rate of speed of the oncoming traffic and proceeded into the intersection. While in the intersection her auto was struck by a motorcycle resulting in the motorcycle operator’s death. Commonwealth witnesses also testified that prior to impact Ms. Barone neither sounded her horn nor did she apply her brakes in an effort to avoid the collision. We are persuaded that based upon the above the jury could not have properly found that Ms. Barone’s actions amounted to “a gross deviation from the standard of care that a reasonable person would observe in [her] situation.” We are convinced that no jury of reasonable men and women could have found a gross deviation from the applicable standard of care in light of the undisputed fact that Ms. Barone waited patiently at the stop sign for several minutes before proceeding into the intersection. Under these circumstances, such conduct could not have established a violation of section 3732.
¶34Accordingly, we would affirm the lower court’s determination that the above evidence was not sufficient to go to the jury.
¶35Order affirmed and defendant discharged.

¶41. Rule 304 was later amended and renumbered to Rule 306. The amended version, however, need not concern us as it became effective only in cases in which the information or indictment was filed on or after January 1, 1978.

¶43. Commonwealth v. Campana, supra, acknowledged that “[w]here an individual is charged with a summary and an indictable offense arisi g out of the same facts and is held for court on the later charge,” it is permissible for a magistrate to hold all charges for disposition at one common pleas proceeding. Campana, 452 Pa. at 253, 304 A.2d at 442. Cf. Commonwealth v. Ray, 448 Pa. 307, 309 n.3, 292 A.2d 410, 412 n.3 (1972). This doctrine was later incorporated into the Pennsylvania Rules of Criminal Procedure by amendment. See Pa.R.Crim.P. 51, Comment (1975). See also Pa.R.Crim.P. 101, Comment (1975). Since by force of this amendment the above class of cases must proceed as court cases, the accused is not guaranteed a disposition other than that provided in Pa.R.Crim.P. 143 (1974). More fundamentally, we perceive no conflict between the teachings of Campana, the above Rules, and the accused’s fundamental rights as guaranteed by the Due Process Clause of the United States Constitution. In any event, Ms. Barone has cited not one case, nor has our independent research unearthed one, which has so construed the rights and privileges secured to the accused by the fourteenth amendment.
¶44. It is beyond question that the Commonwealth has the right to appeal from a lower court order sustaining this type of demurrer. E. g., Commonwealth v. Long, 467 Pa. 98, 354 A.2d 569 (1976); Commonwealth v. Trainor, 252 Pa.Super. 332, 381 A.2d 944 (1977); Commonwealth v. Bey, 221 Pa.Super. 405, 292 A.2d 519 (1972).

¶62. We are not unmindful of the difficulty of the jury’s discriminating between recklessness and negligence when both of the above statutory offenses are submitted for its consideration. We are, however, confident that our lower courts are capable of devising formulations which clarify the distinctions between the two mental states. See Model Penal Code, § 2.02, Comment at 124-28 (Tent. Draft No. 4 1955).
¶63. Parenthetically, while our version of the provision on vehicular homicide does not expressly refer us to other jurisdictions for guidance in construing it, compare Commonwealth v. Sojourner, supra,the absence of such a directive does not prohibit such an inquiry. See 1 Pa.C.S. § 1927 (Supp.1978-79). I am, however, perplexed by the Dissent’s interpretation of the history of this section in other jurisdictions. The Dissent in finding support for it’s result totally ignores three important points: (1) The statutory schemes in the overwhelming majority of these jurisdictions is different from Pennsylvania’s; see National Committee on Uniform Traffic Laws and Ordinances, Traffic Law Annotated, § 11-903, Comment (1972 & Supp.1976); (2) These same jurisdictions either expressly or impliedly have chosen to adhere to the principle that the violation must be culpable at least where imprisonment and a fine are permissible sanctions, see id., and; (3) There is obvious reason why our legislature did not expressly provide that the violation must be reckless, that is, a reckless violation would subject the accused to prosecution under our involuntary manslaughter statute. See 18 Pa.C.S. § 2504 (1973).
