Politely refuse to discuss the accident or your injuries with any representative of the trucking company’s insurance or the truck driver’s insurance company. You can tell them that they may call back once you have hired a lawyer and they are present with you.
It’s important to remember that you are not obligated to answer any of the insurance company’s questions, and you should never say anything like “I’m sorry,” “It wasn’t that bad,” or “My injuries aren’t that serious.” The insurance company can use those statements against you, so if you’re questioning whether or not to say something, take the safer route and say nothing at all.
