State of Tennessee v. Jonathan Campbell

The defendant was convicted of driving under the influence ("DUI"), first offense, and sentenced to eleven months, twenty-nine days in the county jail, with all but forty-eight hours suspended and the balance to be served on probation. In addition, his driver's license was suspended for one year and he was ordered to pay a fine of $350. In his appeal, the defendant argues that the trial court should not have allowed the jury to compare his signature from the morning of the arrest with his signature from another day for the purpose of inferring impairment. Following our review, we affirm the judgment of the trial court.
