Is it ok to discuss the case and give a statement to the truck company before I speak with an attorney?

A: Absolutely not. Truck wrecks can often be catastrophically damaging to you and your family. The job of the truck company safety manager, or investigator or claims agent is to protect the truck company - not you. These people are trained to ask questions and obtain information that is beneficial to them with respect to getting out of liability and not compensating you. If you have been in a truck wreck you will need solid attorney representation.
