When you must file a claim for compensation after a car accident caused by another driver, a basic piece of information you need to know is the amount of the other motorist’s car insurance coverage. You must have this information to determine whether he has enough insurance to fully compensate you for your injuries. If not, you will need to file a claim under your insurance policy. 
In some cases, the driver’s insurance company will refuse to provide you with this information. This should be a red flag that you may have trouble settling your claim for what you deserve, and you should retain an experienced car accident attorney as soon as possible for assistance.
Steps to Take to Collect Information About Insurance Policy Limits
Insurance adjusters sometimes refuse to disclose the insurance policy limits in an effort to wear down a car accident victim or get him to settle his claim for less than he is owed. However, you have a right to this information, and you have options for obtaining it. Here are some ways to do this:
Ask the driver.
Unless the insurance adjuster advised the negligent driver not to talk to you, he may provide this information to you voluntarily if you contact him directly.
Write a letter.
The insurance adjuster may feel more compelled to provide you with the policy limits if you ask more formally in a letter. Be certain to date the letter, and keep a copy of it for your records.
