Evidence that a person was or was not insured against liability is not admissible upon the issue whether he acted negligently or otherwise wrongfully. This rule does not require the exclusion of evidence of insurance against liability when offered for another purpose, such as proof of agency, ownership, or control, bias or prejudice of a witness, or when the court determines that in the interests of justice evidence of insurance or lack of insurance should be permitted. A party intending to offer evidence of insurance or the lack of it should make an offer of proof of such evidence out of the hearing of the jury. If the court determines that such evidence should be disclosed, in the exercise of its discretion the court may direct that such evidence be disclosed to the jury by the court or by the parties in a manner best calculated to serve the interests of justice and avoid prejudice, confusion and waste of time.
