Pros

No pros at this company

Cons

Everything they will lie to you. As a Driver you are required to get a 10 hrs reset these people have you working while in sleeper berth. They write you up for anything meanwhile they are short drivers. Drivers are overworked and the drivers that are there don’t say anything about how illegal they run.
