Do I get legal representation from my old employer if listed as defendant in lawsuit with them

I was in a minor fender bender Apr 9th, 2024, while delivering parts in a work vehicle. I was not cited at the scene or afterward. It was only later determined that I was at fault, but it was never brought to my attention. (By supervisor, or sheriff's office.) I am now being listed as a defendant in a $100k lawsuit in regard to the accident. They are making it seem like I was going 100MPH when it was under 10MPH, as seen in the vehicle's dashcam footage. They brought up my speeding tickets from 2020 and 2021. (2020 there is a 911 call from me in regard to a man pulling a gun on me, and I was trying to get to my husband's job to be able to collect myself. The cop did not take it into consideration when providing me the ticket.) I did my own research and found that the driver received a careless driving ticket in July of 2025 (could have added to the accident, since I have never been found guilty of careless driving, only slightly speeding, which I have not received a ticket since 2021.) The passenger received a speeding ticket Jan 1st, 2026, (testimony from the passenger is then questionable.) My old employer won't answer me about representation. Do I need a lawyer?
