The first steps you'll take after a Massachusetts commercial truck accident are similar to the steps you would take after any motor vehicle accident. You will want to exchange insurance information with the other driver, make a police report, and let emergency personnel check you out or go to your doctor or a hospital to be assessed after the accident. If you are able, you’ll also want to gather whatever evidence you can at the accident scene, such as collecting witness contact information and taking photographs of the crash site.
