It is hard to get the police to amend their police reports. Ideally, you should look at the police report at the scene of the accident and quickly point out any errors to the officer while he is still there. He can then correct the report before filing it. Another option is to make sure you take pictures of the damage to the vehicles soon after the accident. You can use this visual evidence to point out where the damage really occurred and emphasize its true severity. With pictures, the insurance adjuster can see that the report misrepresented key aspects of the car accident.
