You face additional collateral penalties for a DUI charge. You will very likely have to pay more for your insurance premiums after getting a DUI conviction.
You will not be able to drive until you reinstate your license, and you will have to pay exorbitant fees for that reinstatement. Therefore, until you can get those fees together you will have to rely on others to drive you around. These types of transportation problems could make it hard to get to work and ultimately lead to job loss.
Additionally, you could have problems with your employer if the probation department determines that you need inpatient alcohol or drug treatment.
