Okla. Stat. tit. 47, § 47-157.1: Insurance on Department of Transportation, Board of

Agriculture and Department of Human Services vehicles – Kinds and

amounts.

The Department of Transportation, the Board of Agriculture, and

the Department of Human Services of the state are hereby authorized

to carry insurance on vehicles, motorized machinery, or equipment

owned and operated by the Department of Transportation, the Board of

Agriculture, and the Department of Human Services, such insurance to

be of the following kinds and in amounts not exceeding the

following:

1. Bodily injury liability, One Hundred Thousand Dollars

($100,000.00) each person, Three Hundred Thousand Dollars

($300,000.00) each accident;

2. Property damage liability, Fifty Thousand Dollars

($50,000.00) each accident; and

3. Medical and hospital insurance, Five Thousand Dollars

($5,000.00).

Such insurance shall be on standard policy forms approved by the

State Insurance Commissioner and with companies authorized to do

business in Oklahoma, and shall be paid for out of administrative

funds of such departments. Such insurance may cover not only the

department or state agency purchasing the insurance but also the

personal liability of the operator. The ownership, maintenance,

operation and use of motor vehicles and motorized movable equipment

owned, leased, used or operated by such departments or state

agencies named in this section is hereby declared to be a public

governmental function. An action for damages may be brought against

such department or state agency, but the governmental immunity of

such department or state agency shall be waived only to the extent

of the amount of insurance purchased. Such department or state

agency shall be liable for negligence only while such insurance is

in force, but in no case in any amount exceeding the limits of

coverage of any such insurance policy. No attempt shall be made in

the trial of any action brought against any such department or state

agency to suggest the existence of any insurance which covers in

whole or in part any judgment or award which may be rendered in

favor of the plaintiff, and if the verdict rendered by the jury

exceeds the limits of the applicable insurance, the court shall

reduce the amount of said judgment or award to a sum equal to the

applicable limits stated in the policy. To the extent that the

insurer has provided indemnity in the contract of insurance to a

department or state agency described in this section, the said

insurer may not plead as a defense in any action involving insurance

purchased by the authority of this section, the governmental

immunity of either the state or of any department or agency thereof

purchasing insurance pursuant to this section. Venue of all actions

provided for herein shall be in the county of the residence of the

plaintiff or where the cause of action arose, but summons may be

served upon the director, head or governing board or body of the

department or state agency being sued and alleged to come within the

purview of this section, wherever that person may be found. Such

policies shall be filed in the office of the Secretary of State as a

public record.
