The Commonwealth takes this appeal from the Order of November 5, 1993, granting in part defendant’s petition for a writ of habeas corpus and dismissing the charge of driving under the influence of alcohol, 75 Pa.C.S. § 3731(a)(1). A preliminary hearing on the charges wаs held on July 21, 1993 before a district justice, at the conclusion of which all charges were held for court. Defendant filed a petition for writ of habeas corpus on September 2, 1990, and a hearing was held on the petition on September 28, 1993 bеfore the Honorable Ann H. Lokuta of the Court of Common Pleas of Luzerne County. On November 5, 1993, the trial court entered the Order which forms the basis of this appeal.
*364
The method for testing a finding of a
prima facie
case prior to trial, in this Commonwealth, is by a writ of habeas corpus.
Commonwealth v. Hetherington,
To that end, we examine the evidence as established at the habeas corpus hearing. State Police Trooper Todd Leiby testified that on the evening of May 28, 1993, the State Police were operating a field sobriety checkpoint on State Route 11 in Hunlock Township, Luzerne County. As part of the operation, evеry vehicle was being stopped as it passed through the checkpoint. At or around 9:35 p.m., Trooper Leiby stopped defendant’s vehicle, and upon the defendant rolling down his window, the trooper detected a strong odor of alсohol. The trooper also noticed defendant had red, bloodshot eyes, slurred speech and refused to direct his voice toward the trooper. Further, defendant had some difficulty in producing his driver’s license, registration and proof of insurance. Trooper Leiby then requested defendant exit his vehicle and perform a field sobriety test, consisting of a one-leg stand, which defendant failed. At that point, defendant was placed under arrest. Defendant consented to a blood test and he was transported to a local hospital where blood was drawn, indicating a blood alcohol level of 0.16%. Trooper Leiby’s opinion, based upon his education, training and experience was that defendant was under the influence of alcohol to a degree which rendered him incapable of operating his vehicle safely.
On appeal, the Commonwealth argues the above evidence established a prima facie case that dеfendant was operating a motor vehicle while under the influence of alcohol *365 to a degree which rendered him incapable of safe driving. Appellee counters that because Trooper Leiby’s uncontradicted testimony established that appellee was not driving erratically and had committed no moving violation of the Vehicle Code, the evidence was insufficient to maintain a charge under 75 Pa.C.S. § 3731(a)(1).
The Vehicle Code defines the offense оf driving under the influence, in pertinent part, as follows:
§ 3731. Driving under influence of alcohol or controlled substance
(a) Offense defined. — A person shall not drive, operate or be in actual physical control of the movement of any vеhicle while:
(1) under the influence of alcohol to a degree which renders the person incapable of safe driving;
(4) the amount of alcohol by weight in the blood of the person is 0.10% or greater.
75 Pa.C.S. § 3731(a)(1) and (4).
Our Supreme Court has stated:
In order to establish appelleе’s guilt the Commonwealth had to prove: (1) that he was operating a motor vehicle, (2) while under the influence of alcohol to a degree which rendered him incapable of safe driving. 75 Pa.C.S. § 3731(a)(1),
Commonwealth v. Horn,
The statute does not require that a person be drunk, or intoxicated, or unable to drive his automobile safely in traffic, but merely that the Commonwealth prove beyond a reasonable doubt that the defendant was operating his automobile under the influence of intoxicating liquor---The statutory expression “under the influence of intoxi *366 eating liquor” includes not only all the well known and easily recognized conditions and degrees of intoxication, but also any mental or physical condition which is the result of drinking alcoholic beverages and (a) which makes one unfit to drive an automobile, or (b) which substantially impairs his judgment, or clearness of intellect, or any of the normal faculties essential to the safe operation of an automobile,
Commonwealth v. Horn,
Thus, substantial impairment, in this context, means a diminution or enfeeblement in thе ability to exercise judgment, to deliberate or to react prudently to changing circumstances and conditions. Its meaning is not limited to some extreme condition of disability.
Commonwealth v. Griscavage,
The
Griscavage
Court, in reversing, found error in the Superior Court’s “application of а hitherto unapproved rule of law which provided that the manner of operation of an automobile must be extreme and uncontrolled before it may be allowed to serve as a basis for a reasonable inference thаt it was caused by the inference of alcohol.”

We find analogous this Court’s decision in
Commonwealth v. Wilson,
This Court agreed with an earlier Commonwealth Court finding that the legislature intended parking lots to be included within the definition of trafficways. “It would raise form to towering levеls above substance if parking lots, in which vehicular traffic is encouraged and occurs, sometimes at high rates of speed, were to become ‘DWI-free zones,’ in which drunk driving is tolerated from entrance to exit.
Such a construction would seriously undermine the effectiveness of any drunk driving
prohibitions.”
Wilson, supra
at 257,
An Act of Assembly which imposes penal sanctions for violations of its provisions must be strictly construed. 1 Pa.C.S. § 1928.
Commonwealth v. Hill,
Conversely, appellee’s suggested construction of section 3731(a)(1) could result in the following hypothetical situation. A drunken driver is fortuitous enough not to topple safety cones, strike police cruisers or otherwise drive erratically when approaching a sobriety checkpoint. When met by police, however, the driver exhibits an odor of alcoholic beverage, *368 bloodshot eyes, slurred speech, has difficulty producing his driver’s license, registration and insurance cards and is unable to complete successfully a field sobriety test. Nevertheless, by refusing to consent to blood or chemical testing, the driver thwarts any determination that his blood alcohol level was greater than 0.10%. Consequently, the driver may not be charged under 3731(a)(1) or (a)(4). Although the driver would face an automatic one-yeаr suspension of his driving privilege, no criminal sanction would attach. 75 Pa.C.S. § 1547(b)(1). Clearly, the legislature did not intend such a construction, which “would seriously undermine the effectiveness- of any drunk driving prohibitions.” Wilson, supra. Such an interpretation would also render meaningless the operation of sobriety checkpoints, which have proven to be effective deterrents to drunk driving.
We also find instructive a footnote in a Supreme Court decision reached several months before
Griscavage.
In that case,
Commonwealth v. McGinnis,
While the testimony of the police was sufficient to establish their рrobable cause in arresting Appellant and requesting him to submit to a breathalyzer test, it does not follow that their observations of Appellant established a sufficiently independent basis for finding that Appellant was, in fact, guilty of violating 75 Pa.C.S. § 3731(a)(1). Thе witnesses who testified against Appellant observed that Appellant was argumentative, belligerent, fumbled through his cards to find proper identification, had glassy and slightly bloodshot eyes, and had an odor of alcohol about him. No testimony was оffered, however, concerning whether Appellant had trouble walking on his own, whether he staggered, had slurred or incoherent speech, or performed poorly on a physical coordination test. In fact, it was admitted that no sobriety test was conducted in this case.
*369 The fact that a person becomes belligerent or has difficulty in finding his driver’s license or owner’s card under a stressful situation, has bloodshot eyes at 5:00 a.m., or glassy looking eyes when a strong flashlight is turned on him does not establish intoxication. The only evidence supportive of a conclusion of Appellant’s intoxicated state was the observation of the officers that Appellant had an odor of alcohol about him. Without additional testimony to establish whether Appellant could ambulate on his own and speak coherently, or other evidence to show that Appellant was not in control of himself, we find the evidence insufficient to establish that Appellant was under the influence of alcohol to a degree which rendered him incapable of safe driving.
Id.
at 526 n. 4,
In the case before us, Trooper Leiby presented uncontradicted evidence that defendant had a strong odor of alcohol about him and bloodshot eyes. More significantly, defendant had difficulty producing his driver’s license and registration, had slurred spеech and was unable to stand on one foot for more than three seconds. We find this evidence is precisely the additional testimony of which McGinnis speaks and which establishes a prima facie case that appellee was under the influence of alcohol to a degreе which rendered him incapable of safe driving.
For these reasons, we find the trial court erred in dismissing the charge under section 3731(a)(1), and we reverse that portion of the Order of November 5, 1993.
*370 Order reversed in part and case remanded for рroceedings consistent with this Opinion.
Jurisdiction relinquished.
