Will a lawyer cost more if I have more than one DWI?

Not if he knows what he’s doing.  The penalties for you are steeper, but the cost of defense shouldn’t be.

Much of the defense is based upon the police report and the facts surrounding the arrest, not the number of DWIs you have.

Thus, think twice about hiring an attorney that is going to charge you more for subsequent DWIs.  The only time you should consider spending more is if you seriously injure or kill someone after driving drunk.  This is because of the added complexity of the case.
