Opinion for the Court filed by Circuit Judge ROGERS.
Thе question on appeal is whether federal law pre-empts a defective design lawsuit against the American Honda Motor Company for damages arising from injuries suffered by Alexis Geier 1 when her 1987 Honda Accord, which did not have an airbag, crashed into a tree. The district court granted summary judgment for Honda on the ground that the lawsuit was pre-empted by the National Traffic and Motor Vehicle Safety Act of 1966, as amended, 15 U.S.C. § 1381 et seq. (Safety Act), and the Federal Motor Vehicle Safety Standard 208, 49 C.F.R. § 571.208 (1997) (Standard 208), which govеrn the passive safety restraints that automobile manufacturers must install. 2 Joining our sister circuits, we affirm, concluding that Geier’s lawsuit is impliedly pre-empted.
I.
Under the Supremacy Clause of the Constitution, the laws of the United States “shall be the supreme Law of the Land; ... any Thing in the Constitution or Laws of any State to the Contrary notwithstanding.” U.S. Const, art. VI, cl. 2. In applying this Clause, courts have identified three ways in which a federal statute or regulation can pre-empt state law: by express pre-emption, by “field” pre-emption (in whiсh Congress regulates the field “so extensively that [it] clearly intends the subject area to be controlled only by federal law”), and by implied or conflict pre-emption, which applies when a state law conflicts with a federal statute or regulation.
Irving v. Mazda Motor Corp.,
For cars manufactured between September 1, 1986, and September 1, 1987, the inclusion of a driver-side airbag was one of several passive restraint “options” from which car manufacturers could choose in order to comply with Standard 208. 3 See 49 *1238 C.F.R. § 571.208, S4.1.3.1.1 (1997). The effect of Standard 208 on state law is governed by two provisions of the Safety Act. The first, 15 U.S.C. § 1392(d), 4 provides:
[w]henever a Federal motor vehicle safety standard established under this subchapter is in effect, no State or political subdivision of a State shall have any authority either to establish, or to continue in effect, with respect to any motor vehicle or item of motor vehicle equipment any safety standard applicable to the same aspect of performance of such vehicle or item of equipment which is not identical to the Federal standard.
The second provision, 15 U.S.C. § 1397(k),
5
a so-called savings clause, provides that “[cjomplianee with any Federal motor vehicle safety standard issued under this subchapter does not exempt any person from any liability under common law.” Without stating whether it was adopting a theory of express or implied pre-emption, the district court reasoned that § 1392(d) pre-empted Geier’s claim because recovery under her common law tort theory might establish a safety standard that was not identical to Standard 208. Adopting an approach articulated by the First Circuit in
Wood v. General Motors Corp.,
On appeal, Geier contends that the district court erred in granting summary judgment because § 1392(d) expressly preserved all common law claims against pre-emption and the term “standards” in § 1392(d) applies only to state legislation or regulations. Honda maintains that summary judgment was appropriate because the Safety Act either expressly preempts Geier’s lawsuit, or impliedly pre-empts it because a verdict in her favor would conflict with Standard 208. 6
II.
The Suprеme Court has considered preemption under § 1392(d), although it did not directly address the issues presented in the instant appeal.
Freightliner Corp. v. Myrick,
Thus far, five circuit courts of appeal have analyzed the issue of pre-emption under the Safety Act when plaintiffs have brought design defect сlaims based on the absence of airbags. In each case, Section 208 did not require airbags for the model-year cars in question, but presented them as one of several options from which manufacturers could choose. Four of the five circuit courts of appeal held that such claims were impliedly pre-empted, while the Ninth Circuit held that the claims were expressly pre-empted.
See, e.g., Harris,
As noted, Geier contends that § 1397(k) expressly preserved “all common law claims” against pre-emption and that the term “standards” in § 1392(d) applies only to state legislation or regulations. This contention obviously cannot be rejected out of hand, yet nor can Honda’s contention that “§ 1392(d) expressly preempts state safety standards not ‘identical’ to applicable federal standards.” In Honda’s view, because Standard 208 allowed car manufacturers the option of choosing an airbag, a jury verdict in favor of Geier on her design defect claim would require car manufacturers to comply with a different standard. 9
*1240
The language of § 1392(d) is fairly sweeping, providing that when a federal motor vehicle safety standard is in effect, “no State or political subdivision of a State shall have
any
authority either to establish, or to continuе in effect, with respect to any motor vehicle or item of motor vehicle equipment
any
safety standard applicable to the same aspect of performance of such vehicle or item of equipment which is not identical to the Federal standard.” 15 U.S.C. § 1392(d) (emphasis added). At a minimum, this language restricts a State’s authority to enact legislation or regulations that affirmatively require car manufacturers to adopt standards not identical to Standard 208.
See Wood,
On its face, moreover, the term “standard” in § 1392(d) could apply to the requirements imposed by common law tort verdicts. As the Supreme Court has observed, state “regulation can be as effectively exerted through an award of damages as through some form of preventive relief. The obligation to pay compensation can be, indeed is designed to be, a potent method оf governing conduct and controlling policy.”
Cipollone,
Section 1392(d), however, cannot be viewed in isolation,
see American Textile Mfrs. Inst., Inc. v. Donovan,
The conclusion that Geier’s lawsuit is expressly pre-empted by the Safety Act is problematic, however, for two reasons. First, the interpretation of the two provisions adopted by
Harris
is not the only one available. For example, the broad language of the savings clause raises doubts that Congress intended to preserve State authority to impose standards only to the extent that the pre-emption clause did not take that power away. As the Court of Appeals of New York observed, “[i]t strains reason and common sense to suggest that Congress used sweeping language to create a constricted universe.”
Drattel,
Second, the presumption against pre-emption counsels against finding express preemption when the purpose of Congress is not clear from the statute’s language. In light of the apparent tension between §§ 1392(d) and 1397(k), it would be difficult to discern from the Act a “clear and manifest purpose of Congress” to pre-empt a design defect claim based on the absence of an airbag.
See Medtronic,
Ultimately, we need not resolve whether Geier’s claim is expressly pre-empted, however, because we conclude that a verdict in her favor would stand as an obstacle to the federal government’s chosen method of achieving the Act’s safety objectives, and consequently, the Act impliedly pre-empts her lawsuit. The conclusion arises largely from the position advanced by Honda, in the alternative, that state jury verdicts that hold manufacturers liable for not installing airbags will create a conflict with Standard 208.
As a threshold matter, we are unpersuaded by Geier’s contention, relying on Cipollone, that the court cannot reach the implied pre-emption argument bеcause congressional intent is expressly stated in § 1397(k), which saves all common law claims from pre-emption, and therefore only express preemption analysis is applicable. It is true that the Supreme Court in Cipol-lone observed that when Congress has included a provision explicitly addressing the issue of pre-emption, and
when that provision provides a reliable in-dicium of congressional intent with respect to state authority, there is no need to infer congressional intent to pre-empt state laws from substantive provisions of the legislation .... Congress’ enactment of a provision defining the preemptive reach of a statute implies that matters beyond that reach are not pre-empted.
The tension between §§ 1392(d) and 1397(k) prevents the identification of any “express definition” of the reach of preemption in the Safety Act. Furthermore, in
Myrick
the Supreme Court engaged in implied preemption analysis of the Safety Act after concluding that § 1392(d) did not “expressly extinguish state tort law” for no-ABS claims.

Implied conflict pre-emption occurs “where it is impossible for a private party to comply with both state and federal requirements, ... or where state law stands as an obstacle to the accomplishment and execution of the full purposes and objectives of Congress.”

The tortured history of Section 208 demonstrates that federal regulators have vacillated on the relative merits of requiring or including airbags in passenger vehicles.
See Wood,
With this history in mind, and consistent with the policy decision made by the Secretary, we conclude that allowing design defect claims based on the absence of an airbag for the model-year car at issue would frustrate the Department’s policy of encouraging both public acceptance of the airbag technology and experimentation with better passive restraint systems. Even if the Secretary’s gradual adoption of an airbag requirement has increased public acceptance of the technology over tune, concerns about public reaction still existed when Geier’s 1987 Honda was manufactured. Furthermore, regardless of possible fluctuations in public acceptance of airbags at that time, the concern about fostering the most effective passive restraint systems through experimentation remained. Therefore, “[bjecause potential common law liability interferes with the regulatory methods chosen by the federal government to achieve the Safety Act’s stated goals,”

Notes
. Appellants are Alexis Geier, a minor at the time of the accident, аnd her parents, William and Claire Geier. For ease of reference we refer to appellants as "Geier."
. The Safety Act is now codified at 49 U.S.C. § 30101 et seq. Geier's complaint was filed after the recodifictition. The revisions, however, were made "without substantive change” to the underlying provisions. See Pub.L. No. 103-272, § 1(a), 108 Stat. 745, 745 (1994). Because the relevant circuit courts of appeal decisions, the district court, and the parties all use the old designations, we will use them as well.
.The requirements of Standard 208 have become more stringent. After Septembеr 1, 1989, car manufacturers had to install "either an airbag or an automatic seatbelt that would signal the driver with a warning light if the belt became unhooked.”
Harris v. Ford Motor Co.,
.Section 1392(d) is now codified at 49 U.S.C. § 30103(b)(1) (1994), which uses similar language:
[w]hen a motor vehicle safety standard is in effect under this chapter, a State or a political subdivision of a State may prescribe or continue in еffect a standard applicable to the same aspect of performance of a motor vehicle or motor vehicle equipment only if the standard is identical to the standard prescribed under this chapter ....
. Section 1397(k) is now codified, with some changes, at 49 U.S.C. § 30103(e) (1994): "Compliance with a motor vehicle safety standard prescribed under this chapter does not exempt a person from liability at common law.”
. Honda does not maintain that field pre-emption applies.
. The Ninth Circuit, in rejecting Standard 121, recognized that further refinement of the ABS systеm might lead to greater public safety. It thus held that the agency could enforce an ABS requirement if it could produce "more probative and convincing data evidencing the reliability and safety” of vehicles with ABS.
Paccar,
. The Eleventh Circuit recently reaffirmed
Taylor.
In
Irving,
the court noted that although its decision in
Myrick v. Freuhauf Corp.
stated that
Taylor
had been abrogated in part,
see
. However, Geier’s contention that the term "safety standard” in § 1392(d) applies to aspects of performance, while her lawsuit involves a design defect, gets her nowhere for reasons noted by the First Circuit in
Wood,
. In
Medtronic,
five justices agreed that "state common-law damages actions do impose 'requirements’ and are therefore preempted where such requirements would differ from those imposed” by the statute.
. H.R.Rep. No. 1776, at 24 (1966) ("It is intended, and this subsection [§ 1397(k)] specifically establishes, that сompliance with safety standards is not to be a defense or otherwise to affect the rights of parties under common law...."); S.Rep. No. 1301, at 12 (1966), U.S. Code Cong. & Admin. News 1966 at 2709, 2720 (noting that "the Federal minimum safety standards need not be interpreted as restricting State common law standards of care. Compliance with such standards would thus not necessarily shield any person from product liability at common law").
. Although these circuits reject express preemption of no-airbag claims, their analysis differs. The First Circuit, for exаmple, suggested that Congress in 1966 did not contemplate the development within state tort law of 'design defect claims that might conflict with federal safety standards.
Wood,
. Contrary to Geier’s сontention, our conclusion is not at odds with the position taken by the United States in prior Safety Act cases. The United States has previously contended that § 1392(d) "does not expressly or impliedly preempt design defect tort actions based on the claim that a vehicle was defective simply because it did not contain an airbag.” Brief of the United States as Amicus Curiae, on Petition for a Writ of Certiorari at 7,
