Impaired driving convictions do not automatically show up on a credit report, though background checks are a part of the data collection process. The information is not a part of the final summary, but can impact the overall score when the rating is calculated. If a fine has been sent to a collection agency, then that status can affect a credit rating. The truth is, if a fine is outstanding and the court has sent it to a collection agency, the defendant is lucky. The court will usually arrest the defendant for failure to pay, failure to appear, or both. There are, however, some instances where a DUI can affect a credit report indirectly.
