I have been driving for 4 months and have been let go by a major carrier US express for having to many preventable accidents. I have 2 Preventables on my DAC. One for hitting low bridge in Chicago (no marking for height on bridge). It still was my fault and take resposibility. Number 2 I hit a parked car at loading dock. Neither accident appears on my MVR. No cops at either accident. I have a clear MVR. How much emphasis is put on a Dac report when MVR is clear.
