Plaintiff Tina Hintz brought this diversity action against Defendants Leslie Jami-son, in his capacity as Dix Township Road Commissioner, and Dix Township, alleging that the defendants breached their duty to maintain safe roads and thus caused an automobile accident in which Hintz was injured. The jury found in favor of Hintz. The defendants appeal the district court’s denial of their motions for a directed ver-diet, for judgment notwithstanding the verdict, and for a new trial. We affirm.
I
On the morning of July 27, 1979, Tina Hintz and her husband, Robert Hintz, were traveling west on a Dix Township road in Ford County, Illinois. 1 This road terminated in a T-intersection at a north-south township road. The township had placed a double-arrow sign west of the intersection to warn west-bound traffic, but had installed no stop signs or advance warning signs. Robert Hintz, who was the driver, testified that there also was loose gravel in the intersection. Because the morning was foggy, the plaintiff and her husband did not see the warning sign until they were about twenty-five feet away from the intersection. Robert Hintz braked and tried to turn sharply south, but his car skidded into a ditch.
Although Robert Hintz sustained no injuries in the accident, Tina Hintz was not so fortunate. She sustained a back injury for which she has had surgery twice and a neurological injury that has caused bowel and bladder dysfunctions. She testified that several of her toes have curled under her feet, and that she still suffers from continual back pain, numbness in her legs, and bladder accidents.
At the time of the accident, Defendant Jamison, as Dix Township Road Commissioner, was in charge of posting and maintaining the township’s road signs. In Illinois, a township is liable for the tortious acts of its road commissioner acting in his official capacity.
See Hennigs v. Centreville Township,

The defendants’ principal argument on appeal is that they are immune from liability under the Tort Immunity Act. Ill.Stat. Ann. ch. 85, § 1-101 (Smith-Hurd 1965). The Act confers immunity for public officials’ discretionary acts,
id.
§ 2-201, and provides that local governmental bodies are not liable for injury caused by an employee where the employee is not liable,
id.
§ 2-109. Another section provides that nothing in the Act shall “deprive any public entity of any defense heretofore existing and not described herein.”
Id.
§ 2-111. Finally, Section 9-103(c), which states that any insurance policy must waive the insurance company’s right to refuse payment because of the “non-liability of the insured public entity ... and its immunity from suit by reason of the defenses and immunities provided in this Act,” has been interpreted by Illinois courts to provide that procuring insurance waives a public body’s immunity.
See, e.g., Sullivan v. Midlothian Park District,
The plaintiff apparently concedes that Jamison’s alleged failure to post warning signs was a discretionary act protected by the public official immunity of Section 2-201. She argues, however, that Dix Township’s insurance policy waived both Jami-son’s and the township’s immunity.
Before 1959, local governmental bodies and their employees generally were protected against suit in Illinois by a doctrine of quasi-judicial immunity. In
Molitor v. Kaneland Community Unit District No. 302,
The defendants argue that public official immunity existed before the Act was passed, and thus is a “heretofore existing” defense preserved by Section 2-111 that is not waived when a public entity procures insurance. Although Section 2-111 also states that the defense not be “described” in the Act, the defendants contend that the Illinois Supreme Court’s decision in
Lansing v. County of McLean,
The defendants misapply the court’s holding in
Lansing.
That case did not involve governmental immunity, but rather a defense that had been unaffected by
Molitor.
Although the Tort Immunity Act did not impose new liability where none had existed previously, it did confer immunity for local governmental units and their employees, and provide that such immunity would be waived when the governmental body procures insurance. We are not convinced by the defendants’ contention that public official immunity was not affected by
Molitor
and thus is a “heretofore existing” defense that may not be waived by insurance. Rather, whether public officials still enjoyed immunity after the
Molitor
decision was disputed by Illinois courts.
Compare, e.g., Blazer v. Highway Commissioner of Marengo Township,
Ill
The defendants raise several other objections, all of which involve decisions that are left either to the discretion of the judge or the wisdom of the jury. We conclude that the jury’s verdict was supported by the evidence, and thus the district court properly denied the defendants’ motions for a directed verdict and for judgment notwithstanding the verdict. Furthermore, the district court did not abuse its discretion in admitting the testimony of the plaintiff’s expert witness, a civil engineer. The expert’s technical understanding of Illinois’ signing requirements could help the jury understand the evidence, as permitted un
*539
der Federal Rule of Evidence 702. Also, the district court gave proper jury instructions regarding comparative negligence in Illinois. Finally, the jury’s money award is not “so large as to shock the conscience of the court.”
Huff v. White Motor Corp.,
The judgment of the trial court is affirmed.
Affirmed.
Notes
. At the time of the accident, Tina Hintz was a resident of Illinois. She moved to Oklahoma before instituting this suit.
. Section 3-102(a) provides:
Except as otherwise provided in this Article, a local public entity has the duty to exercise ordinary care to maintain its property in a reasonably safe condition for the use in the exercise of ordinary care of people whom the entity intended and permitted to use the property in a manner in which and at such times as it was reasonably foreseeable that it would be used, and shall not be liable for injury unless it is proven that it has actual or constructive notice of the existence of such a condition that is not reasonably safe in sufficient time prior to an injury to have taken measures to remedy or protect against such condition.
Section 3-104(b) provides:
Neither a local public entity nor a public employee is liable under this Act for any injury caused by the failure to provide traffic warning signals, signs, markings or other devices unless such a signal, sign, marking or device was necessary to warn of a condition which endangered the safe movement of traffic, and which would not be reasonably apparent to or anticipated by a person in the exercise of due care.
