Takeaway

In short, this case holds that a State cannot substantially obstruct efficient interstate trucking with a purported safety rule when the safety benefit is unsupported and the scheme appears to shift interstate traffic and its costs onto other States.

Background

Consolidated Freightways, a nationwide motor carrier, used 65-foot double-trailer trucks on interstate routes. Iowa generally limited truck combinations to 55 feet and allowed doubles only up to 60 feet. Unlike other Midwestern and Western States, Iowa barred Consolidated’s 65-foot doubles from traveling through the State. The carrier therefore had to use smaller equipment, separate and shuttle trailers, or reroute its trucks around Iowa.

Iowa defended the restriction as a highway-safety measure. But its statutory scheme contained exemptions, including allowances for certain vehicles serving local interests and for border cities to adopt the longer limits of neighboring States. The State also permitted specially authorized oversized shipments in circumstances that particularly benefited Iowa businesses or residents.

After a 14-day trial, the District Court found that 65-foot doubles were at least as safe overall as the 55-foot singles and 60-foot doubles Iowa allowed. It held that Iowa’s restriction imposed a substantial burden on interstate commerce without a meaningful safety justification. The Eighth Circuit affirmed, and the Supreme Court affirmed that judgment.

Issues

Issue #1

Whether Iowa’s prohibition of 65-foot double-trailer trucks on major interstate highways and nearby access roads imposed an unconstitutional burden on interstate commerce.

Holding

Yes. Iowa’s truck-length restriction violated the dormant Commerce Clause because it substantially burdened interstate commerce while producing no significant, nonillusory safety benefit.

Reasoning

The Commerce Clause limits state regulation even when Congress has not enacted governing legislation. States retain broad authority over matters of local concern, especially highway safety, and bona fide safety rules ordinarily receive a strong presumption of validity. But a court must still make a sensitive assessment of the State’s asserted safety interest in light of the regulation’s burden on interstate commerce; simply calling a measure a safety regulation is not enough.

The trial record supported the lower courts’ finding that 65-foot doubles were at least as safe overall as the shorter trucks Iowa permitted. Doubles were comparable in braking, turning, and maneuvering; were less susceptible to wind and off-tracking; and produced less splash and spray. Although doubles could be more prone to jackknifing and could not back up as far, those concerns had limited importance on divided interstate highways, and 65-foot doubles were no more prone to jackknifing than the 60-foot doubles Iowa allowed.

The comparative accident evidence also failed to establish a meaningful safety advantage for Iowa’s ban. One study of Consolidated’s trucks traveling identical routes found the singles had more injuries than the doubles, and Iowa’s own transportation study concluded that 65-foot doubles had not been shown less safe than either 60-foot doubles or conventional tractor-semitrailers. Iowa could identify no statistically significant study showing that its banned trucks were less safe overall.

The restriction materially disrupted interstate trucking. Carriers using 65-foot doubles had to reroute around Iowa, break apart their trailer combinations, or use less efficient trucks. The evidence showed annual trucking costs of roughly $12.6 million, including about $2 million for Consolidated alone. The ban also could increase total highway mileage, fuel use, road wear, and accidents, because the same freight had to be carried by more smaller trucks or sent on longer detours.

Iowa’s exemptions and their history reduced the usual deference owed to a facially neutral safety rule. The border-city and locally beneficial exemptions gave Iowa interests access to advantages of longer vehicles while limiting interstate through traffic. Governor Ray’s veto message concerning proposed legalization of 65-foot doubles further suggested an aim to keep additional out-of-state truck traffic, and its costs, outside Iowa. A State may not advance parochial interests by forcing safe interstate traffic to detour through neighboring States.

Because the burden on interstate commerce was substantial and Iowa had not demonstrated a significant countervailing safety interest, the Court held the restriction unconstitutional. The Court did not decide whether the law independently discriminated against interstate commerce, and the ruling was limited to the use of 65-foot doubles on major interstate highways and the requested nearby access roads.

Concurrences

Justice Brennan

Reasoning

Justice Brennan, joined by Justice Marshall, agreed that Iowa’s ban was unconstitutional but rejected the plurality’s focus on whether trial evidence proved 65-foot doubles safer or less safe than shorter trucks. In his view, courts should not second-guess lawmakers’ empirical judgments so long as those judgments are rational; instead, the inquiry should examine the regulatory purposes actually pursued by the lawmakers and the evidence available to support those purposes.

He concluded that Iowa’s actual purpose in retaining the restriction was not a judgment that 65-foot doubles were inherently unsafe. The statute’s history, Governor Ray’s veto of legislation that would have permitted 65-foot doubles, and Iowa’s own litigation position showed that the State sought to discourage interstate truck traffic, thereby reducing road wear, accidents, and related costs within Iowa.

That objective was constitutionally impermissible because Iowa sought to protect itself by shifting traffic, costs, and accident risks onto neighboring States. A State may not avoid its fair share of the burdens of the national transportation system by requiring safe interstate vehicles to travel farther through other jurisdictions. Brennan therefore would treat Iowa’s parochial traffic-diversion policy as protectionist legislation subject to a virtually per se rule of invalidity.

Dissents

Justice Rehnquist

Reasoning

Justice Rehnquist, joined by Chief Justice Burger and Justice Stewart, would have upheld Iowa’s law. He stressed that every State regulates truck length and that Iowa was not alone in barring 65-foot doubles; several States, including States along Interstate 80, imposed similar restrictions. In his view, the Court improperly treated Iowa as an isolated obstacle to interstate commerce.

He argued that highway-safety regulations deserve exceptional deference under the dormant Commerce Clause. Courts should not select the best safety rule or weigh marginal safety gains from a 60-foot limit against the costs of barring a 65-foot truck. Once a legislature has chosen a rational safety measure whose benefits are not merely slight or illusory, the policy judgment belongs to the State unless Congress chooses to establish a national standard.

In his view, Iowa had supplied enough evidence to show that truck length could rationally relate to safety. Longer vehicles take more time to pass, may create longer exposure to splash and spray, can obstruct intersections and accident scenes, and doubles can be less stable and more likely to jackknife. The lower courts erred by demanding proof that the prohibited 65-foot doubles were less safe overall than every permitted vehicle.

Justice Rehnquist also rejected the plurality’s reliance on exemptions and the Governor’s veto message as proof of protectionism. The 60-foot limit predated the vetoed 1974 legislation, and the border-city exemption was available to interstate as well as Iowa shippers in the covered cities. He warned that treating a State’s choice of a stricter safety standard as protectionism would leave other States uncertain whether their longstanding truck-length laws could survive judicial review.
