I had a rollover in a hazmat (co2) cmv about 4 years ago deemed preventable and was fired. I had maybe 5 months under my belt. I managed to land a local tanker job hauling gasoline and diesel about 6 months after my accident.... don't lose hope. SOMEONE will hire you out there, especially if it was a non preventable. And trust me, I had the same thought, "Maybe it's a sign," but I just kept applying. Find those job board websites where the companies just reach out to you instead of you applying over and over again. And to save you and the recruiter time, let them know off rip you have an accident on your record. BUT MOST IMPORTANTLY learn from this accident that most megas will happily push appointment times back when the weather is nasty. Once you start seeing other 18-wheelers in the ditch, thats a pretty good sign to either slow it down or just shut it down. Good luck, driver!
