Opinion

Wilkie, J.

The issues involved on these appeals from the judgments entered following this fifty-four-day jury trial naturally divide themselves, as does the opinion, into three subjects: liability, damages and coverage. We will consider them in that order.

I.Liability

The issues presented on the liability phase of this collection of cases are as follows:

1. Did the expert witness, Professor James Van Vleet, presented by Badger State give an opinion based upon unestablished assumptions ?

2. Was his opinion on redirect examination that a “scuff mark” was “possibly” made by the (Kohnke) Cadillac’s right rear tire properly received and not prejudicial?

3. Was it error to exclude the prior inconsistent statement made by Gerald Peil to the investigation officer?

1. Expert opinion.

General Casualty urges that Professor Van Vleet’s “expert opinion” was based upon unestablished assumptions. If this is true, a finding based on such opinion cannot be sustained. 1 A search of the record, however, does not substantiate appellant’s contention on this point.

*176 Certain exhibits presented at trial, notably photographs of the accident scene immediately after the collision, show the Cadillac in its final resting position. These photographs show a long skid mark leading up to the Cadillac’s left rear wheel. The photographs, however, do not clearly disclose whether the skid mark extends beyond the rear wheel and under the rear of the car, i.e., whether the skid mark was in fact made by the left rear wheel or the right rear wheel. It is clear from the evidence, however, that if the skid mark was in fact made by the left rear wheel, the Cadillac was in its proper lane at the time of the collision; while if the skid mark was made by the right rear wheel of the Cadillac, the collision then must have occurred in the Pontiac’s lane.

Appellant contends that Professor Van Vleet based his opinion that the collision occurred in the Cadillac’s lane on the assumption that the skid mark was in fact caused by the left rear wheel; and further, that he assumed this because of his opinion that the collision occurred in the Cadillac’s lane. In short, appellant urges that Professor Van Vleet’s opinion was entirely speculative since based on mere assumption of facts not in evidence.

Professor Van Vleet’s opinion was based on a hypothetical question phrased by counsel for Badger State. The hypothetical, as posed, was based in part on testimonial evidence, in part on photographic exhibits, especially those showing the skid marks, and on his expertise and Newton’s laws. The original hypothetical contained the following phrase:

“As shown on Exhibits 1, 1-A, 22 and 22-A a tire or skid mark made by the left rear tire of the Cadillac automobile extends from the south to the north leading into the left rear tire of the Cadillac as shown . . . .” (Emphasis added.)

This hypothetical was objected to, in part because it assumed the skid mark was made by the left rear tire *177 of the Cadillac. This objection was sustained. Thereafter, the hypothetical was rephrased with respect to that objection as follows:

“A tire or skid mark from the south to the north leading to the left rear wheel of the Cadillac as shown . . . .” (Emphasis added.)

Counsel then asked:

“Professor, based upon that hypothetical question and assuming all of those facts set forth in the hypothetical question, including all of the facts revealed by the pictures, which you have studied, do you have an opinion to a reasonable degree of scientific probability as to whether the impact between the Cadillac and the Pontiac occurred in the east lane or in the west lane ?” (Emphasis added.)

The witness replied he did and stated:

“It is my opinion that the contact, the collision, occurred in the northbound or east lane [Cadillac’s]. That is brought out by the location of the debris in that lane.” (Emphasis added.)

Appellant here contends that this opinion should have been stricken, as should all of his testimony have been, because the testimony was merely a series of opinions based upon other opinions.

a. Collision lane. The record clearly establishes that Professor Van Vleet’s opinion with respect to the lane in which the collision occurred was not based upon whether the skid mark was in fact made by the left rear tire of the Cadillac. As noted above, the professor stated his opinion was based upon the trail of debris leading to the front of the Cadillac. The evidence is uncontradicted that this debris began on the east [Cadillac’s] side of the center line and ended on the west side where the front of the Cadillac came to rest.

Further, he stated that it was a physical impossibility for the Cadillac to have been moved laterally four feet *178 (as was testified to by one of the experts), and then proceed down the road to its final resting place as the liquid debris indicated it did.

Finally, he stated several times on cross-examination that the skid mark was not the basis for his opinion that the collision occurred in the Cadillac’s lane, but was merely corroborating evidence. This is demonstrated by the following exchange during his cross-examination:

“Q. Let me ask you this, Professor: Do you base your opinion in any degree that the impact occurred in the Cadillac’s lane upon the assumption that the tire mark is from the left rear wheel ?
“A. No, I look on it solely as a corroborating fact.
“Q. So we can remove that factor from the basis of your opinion, is that correct?
“A. It is a factor which re-enforces my opinion. It is a factor that makes me confident in this.
“Q. I just really want to know, do you rely upon your opinion, as you stated, that the tire mark is from the left rear ? Do you rely upon that assumption or that conclusion in arriving at your opinion that the accident happened in the Cadillac’s lane? Now, can you answer that question ?
“A. No, I don’t.rely or depend on that being the left rear wheel. I rely on the fact that the droppings are on the—
“Q. You’ve said that.” (Emphasis added.)

The witness was permitted to finish his answer and he again stated his opinion was based upon “the indisputable path that the droppings from the engine compartment left on the pavement as clearly seen on this photograph . . . .” (All witnesses, including the investigating officer, agreed as to the location of the debris path.)

b. Skid mark.
