The question asks about the proportion of accidents that involved more than one vehicle. Looking at the table, we see that there were 325 accidents involving more than one vehicle (257 + 68). To find the proportion, we divide this number by the total number of accidents: 325/400 = 0.8125 or 81.25%. Therefore, the correct answer is B.
