I've Heard That It is Better to Represent Myself Because Hiring a DUI Attorney Can Be Expensive. Is That True?

No, it's not true. It is almost never the case where it is more beneficial to represent yourself. The reason is for DUI, the consequences are so great, even for a first time offender. A person is looking at high fines, they're looking at license suspensions. Things that could really affect their livelihood. It really is important to have an attorney for those kinds of cases.
