Appellants filed an action in United States District Court on September 20, 1982 challenging the constitutionality of a District of Columbia ordinance banning the sale, use, or “possession in a motor vehicle” of “any device designed to detect or counteract police radar.” D.C. Commissioner’s Order 61-2606, reprinted in D.C. Pol.Reg., Art. 25, § 16, 18 D.C.M.R. § 736 (1981). 1 After some preliminary skirmishing, the District Court granted summary judgment to appellees. We here affirm the District Court’s order.
I. Background
Appellants include a manufacturer and a retailer of radar-detecting devices for use in motor vehicles, as well as George Sadler, a Maryland resident who frequently travels interstate by automobile. In one such journey through the District, his radar detector was confiscated and he was fined $50 for violating the Commissioner’s Order banning radar detectors (hereinafter referred to simply as “the Order”). Appellants brought this action against the District of Columbia, the Mayor, and the Chief of Police. They sought issuance of a declaratory judgment that the Order was unconstitutional on two grounds.
First, appellants alleged that, because no other states banned mere possession of radar detectors, the Order was an impermissible burden on interstate commerce. Second, they alleged that the Order was over-broad and vague in violation of the Due Process Clause. 2 In addition to the deelar- *112 atory judgment, appellants sought an injunction against any attempt by appellees to enforce the Order and a court order directing appellees to return Mr. Sadler’s $50 and his radar detector. After discovery was completed, the District Court granted appellees’ motion for summary judgment on the ground that appellants had failed to state a claim on which relief could be granted.
II. Commerce Clause
Appellants wisely do not argue that a statute banning the
use
of radar detectors would violate the Commerce Clause. Rather, they focus their attack on the fact that, although two states seem to prohibit the use of radar detectors, the District is apparently the only jurisdiction in the country that bans the mere
possession
of radar detectors. Appellants argue that owners of radar detectors are thus at risk whenever they travel through the District — even if their detectors are disconnected or even if they are stored in a vehicle’s back seat or in the trunk. This, according to appellants, is an impermissible burden on interstate commerce. It is therefore allegedly subject to the standard dormant Commerce Clause balancing test, in which the “weight and nature of the state regulatory concern” is viewed “in light of the extent of the burden imposed on the course of interstate commerce.”
Raymond Motor Transportation, Inc. v. Rice,
Appellants object to the grant of summary judgment because they claim to be able to introduce evidence demonstrating the ineffectiveness of banning radar detectors in promoting enforcement of highway speed limits. They also claim to be able to prove that the Order puts a very heavy burden on interstate commerce. Therefore, appellants argue, at the very least application of each leg of the balancing test raises factual issues that can only be resolved at trial on the merits. It would follow that summary judgment in this case is inappropriate.
Because we believe that appellants misconceive the scope of our review in dormant Commerce Clause cases of this type, we have no difficulty in affirming the District Court’s disposition of this case. The Supreme Court itself has admitted that it has “employed various tests to express the distinction between permissible and impermissible impact upon interstate commerce” and that “experience teaches that no single conceptual approach identifies all of the factors that may bear on a particular case.”
Raymond Motor Transportation, Inc. v. Rice, supra,
First, state laws are most apt to run afoul of the dormant Commerce Clause when they are based on protectionist rationales,
see, e.g., Philadelphia v. New Jersey,
A second point that emerges from the cases is that' state safety regulations are accorded particular deference in Commerce Clause analysis.
See, e.g., South Carolina State Highway Dep’t v. Barnwell Bros., Inc.,
Appellants do not argue — nor could they — that the Order challenged here is overtly protectionist or even has an effect that favors in-state commerce. All sale of these devices within the District is banned. Moreover, the Order was clearly designed to promote highway safety by encouraging obedience to speed limits; the assumption is that a driver unaware of whether a police radar unit is near at hand will be more likely to obey the speed limit than one who can rest assured that no radar unit is near enough to detect his transgressions. Thus the Order comes before us in the strongest possible posture. In these circumstances we need not perform any fine balancing tests or inquire closely into the validity of the local government’s reasonable factual assumption. Having satisfied ourselves that the local government’s safety rationale is not “illusory” or “nonexistent,” our inquiry is at an end.
The parties in this case expended considerable effort in the District Court arguing about the construction of the Order. Appellants argued that its ban on mere possession of radar detectors would extend to the innocent possession of radar detectors in, for instance, an unopened box in the trunk of a car or to a truck carrying a shipment of new radar detectors through the District to a retailer in another state. We need not decide whether, if the Order indeed extended so far, it would violate the strictures of the Commerce Clause, for the District of Columbia has never threatened to enforce the statute against them if they engaged in such conduct.
See Steffel v. Thompson,
III. Due Process
Appellants asked the District Court to declare the Order unconstitutional under the Due Process Clause as well as the *114 Commerce Clause. Their due process claim is grounded on their allegation that the Order suffers from overbreadth and vagueness.
Appellants’ overbreadth challenge must fail because there is simply no doctrine that requires that, when the legislature enacts a statute that does not reach substantial constitutionally protected conduct, it must tailor the statute narrowly to accomplish the goals it intends to reach.
See, e.g., Williamson v. Lee Optical Co.,
Appellants’ vagueness challenge must fail as well. Appellants’ only possible challenge would be that the Order is impermissibly vague as applied to their own conduct,
see, e.g., Kolender v. Lawson,
IV. Conclusion
For the reasons given above, we affirm the District Court’s judgment in this case.
Affirmed.
Notes
. The exact text of the Order is:
No person shall sell or offer for sale in the District any device designed to detect or counteract police radar.
No person shall use or have in his possession in an automobile in the District any device used to detect or counteract police radar. This section does not apply to any vehicle or equipment used by the Armed Forces of the United States.
. Appellants also alleged that the Order was preempted by the Communications Act, 47 U.S.C. § 151
et seq.,
and subsequent regulations issued by the Federal Communications Commission, and thus violated the Supremacy Clause. The District Court noted that this same argument had previously been presented in
