It's too early in the morning for me to find, dust off and then read my contract book, but I always thought that they were supposed to let you work on the inside while the accident is being investigated. It sounds as though they have done this and found you to be at fault, hence the suspension. You should file for unemployment. Also, and this may differ where you work, but here in Upstate NY our benefits are quarterly--you must work 36 days this quarter to earn benefits for the followiing quarter. You should be fine as far as benefits go. Good luck.
