(1) Any rate, rating schedule, or rating manual for the liability, personal injury protection, and collision coverages of a motor vehicle insurance policy filed with the office may provide for an appropriate reduction in premium charges as to such coverages when the principal operator on the covered vehicle has successfully completed a driver improvement course approved and certified by the Department of Highway Safety and Motor Vehicles which is effective in reducing crash or violation rates, or both, as determined pursuant to 1s. 318.1451(5). Any discount, not to exceed 10 percent, used by an insurer is presumed to be appropriate unless credible data demonstrates otherwise. (2) The premium reduction authorized by this section shall be effective for an insured for a 3-year period after successful completion of the approved course, except that the insurer may require, as a condition of maintaining the reduction, that the insured:
(a) Not be involved in an accident for which the insured is at fault; and
(b) Not be convicted of or plead guilty or nolo contendere to a moving traffic violation.
(3) The organization offering the course shall, upon a person’s successful completion of the course, issue the person a certificate that the person may use to qualify for the premium discount authorized by this section.
(4) This section does not apply if the driver improvement course is taken in lieu of a court appearance for a traffic infraction as provided for in s. 318.14(9). However, the five-election restriction enumerated in that section is not applicable to taking the course for the purposes of receiving insurance premium reductions.
