This diversity action arose out of an automobile accident which occurred on a county road near Grundy Center, Iowa. At the trial the federal district court instructed the jury under counts of ordinary negligence and res ipsa loquitur and refused to apply the Iowa guest statute, Iowa Code § 321.494 (1973). 1 The plaintiff, Francisco Aguilar, was awarded damages for personal injuries against the defendants Elgin Venenga, the owner of the automobile, and Santiago Flores, the driver at the time of the accident. The defendants have appealed.
On May 16,1973, Flores offered Aguilar a gratuitous ride from Grundy Center, Iowa, to Waterloo, Iowa, so Aguilar could look for employment in Waterloo. The evidence showed the defendant Flores had been drinking excessively. During the return trip he drove the automobile into a ditch. Aguilar got out of the car, allegedly to push it or to direct Flores out of the ditch. The *1162 automobile was subsequently backed into Aguilar and he suffered personal injuries.
The major issue on appeal is whether the Iowa guest statute is applicable so that the defendant may assert the defense of assumption of risk. All parties concede that Iowa law controls.
In an early Iowa case, the Supreme Court of Iowa announced that it would apply a strict construction to the Iowa guest statute. Under this construction the application of the guest statute depended on whether the plaintiff was actually “riding in”

the vehicle at the time of the accident.
See Puckett v. Pailthorpe,
In 1962 the court disavowed the application of a strict construction of the statute followed in
Puckett
and indicated that the rule of liberal construction was now well-established. In
Rainsbarger v. Shepherd,
Although our guest statute is in derogation of the common law it is to be liberally construed with a view to promote its objects and assist the parties in securing justice [citations omitted].
In applying the guest statute in
Rainsbarger
the court quoted with approval from
Tallios v. Tallios,
The beginning and end of that relation is not unlike the beginning and end of the relation of carrier and passenger for hire in a public conveyance. In the latter case the relation begins with the attempt of the passenger to enter the conveyance and ends when he has alighted in safety on completion of the journey. . So, the relation of host and guest between automobile owner or driver and a passenger riding without payment of compensation begins when the guest attempts to enter the automobile, and ends only when he has safely alighted at the end of the ride.
The
Rainsbarger
opinion similarly relies on
Castle v. McKeown,
The federal district court here determined that
Rainsbarger
is the Supreme Court of Iowa’s most recent pronouncement regarding who is a guest and that it indicates that the court would apply a liberal construction to the guest statute. The court determined however, that in
Keasling v. Thompson,
*1163
Although “great weight” is to be accorded to the district court’s determination of local law, this court is not bound by that determination.
Carson v. National Bank of Commerce Trust and Savings,
[T]he highest court of the state is the final arbiter of what is state law. When it has spoken, its pronouncement is to be accepted by federal courts as defining state law unless it has later given clear and persuasive indication that its pronouncement will be modified, limited or restricted [citation omitted].
West v. American Telephone and Telegraph Co.,
Here the district court apparently determined that the Keasling opinion was “clear and persuasive” indication that the Supreme Court of Iowa would no longer apply the Rainsbarger “liberal” construction view of the guest statute. We cannot agree.
The Keasling case was an attack on the constitutionality of the Iowa guest statute under equal protection and due process challenges. There was no question of, and no determination made as to, whether a “strict” or “liberal” construction should be applied in determining who is a guest. Although four dissenting justices indicated that they felt the statute was unconstitutional, and three concurring justices suggested it was unwise, there is no “clear and persuasive” indication that the court would overrule its Rainsbarger decision. To the contrary, we cannot conclude from Keasling that the Iowa court would apply the statute any differently than before.
The court in
Horst v. Holtzen,
We find that the district court should have accepted the last pronouncement of the Supreme Court of Iowa in Rainsbarger as defining Iowa state law. It should have submitted the case to the jury under the Iowa guest statute. In view of our holding requiring a new trial, we need not pass on the other issues raised.
We vacate the judgment for the plaintiff, reverse and remand for a new trial.
Notes
. The Iowa guest statute provides:
The owner or operator of a motor vehicle shall not be liable for any damages to any passenger or person riding in said motor vehicle as a guest or by invitation and not for hire unless damage is caused as a result of the driver of said motor vehicle being under the influence of an alcoholic beverage, a narcotic, hypnotic, or other drug, or any combination of such substances, or because of the reckless operation by him of such motor vehicle.
