For the purposes of this section, any conviction for a violation of s. 327.35; a previous conviction for the violation of former s. 316.1931, former s. 860.01, or former s. 316.028; or a previous conviction outside this state for driving under the influence, driving while intoxicated, driving with an unlawful blood-alcohol level, driving with an unlawful breath-alcohol level, or any other similar alcohol-related or drug-related traffic offense, is also considered a previous conviction for violation of this section. However, in satisfaction of the fine imposed pursuant to this section, the court may, upon a finding that the defendant is financially unable to pay either all or part of the fine, order that the defendant participate for a specified additional period of time in public service or a community work project in lieu of payment of that portion of the fine which the court determines the defendant is unable to pay. In determining such additional sentence, the court shall consider the amount of the unpaid portion of the fine and the reasonable value of the services to be ordered; however, the court may not compute the reasonable value of services at a rate less than the federal minimum wage at the time of sentencing.
