6. (1) Notwithstanding any provision of this section or any other law to the contrary, the director of the department of revenue or his or her agent shall order the revocation of a driver's license upon its determination that an individual holding such license was involved in a physical accident where his or her negligent acts or omissions contributed to his or her vehicle striking a highway worker within a designated construction zone or work zone where department of transportation guidelines involving notice and signage were properly implemented. The department shall make its determination of these facts on the basis of the report of a law enforcement officer investigating the incident and this determination shall be final unless a hearing is requested and held as provided under subdivision (2) of this subsection. Upon its determination that the facts support a license revocation, the department shall issue a notice of revocation which shall be mailed to the person at the last known address shown on the department's records. The notice is deemed received three days after mailing unless returned by postal authorities. The notice of revocation shall clearly specify the reason and statutory grounds for the revocation, the effective date of the revocation which shall be at least fifteen days from the date the department issued its order, the right of the person to request a hearing, and the date by which the request for a hearing must be made.
(2) An individual who received notice of revocation from the department under this section may seek reinstatement by either:
(a) Taking and passing the written and driving portions of the driver's license examination, in which case the individual's driver's license shall be immediately reinstated; or
(b) Petitioning for a hearing before a circuit division or associate division of the court in the county in which the work zone accident occurred. The individual may request such court to issue an order staying the revocation until such time as the petition for review can be heard. If the court, in its discretion, grants such stay, it shall enter the order upon a form prescribed by the director of revenue and shall send a copy of such order to the director. Such order shall serve as proof of the privilege to operate a motor vehicle in this state, and the director shall maintain possession of the person's license to operate a motor vehicle until the termination of any suspension under this subsection. The clerk of the court shall notify the prosecuting attorney of the county, and the prosecutor shall appear at the hearing on behalf of the director of revenue. At the hearing, the court shall determine only:
a. Whether the person was involved in a physical accident where his or her vehicle struck a highway worker within a designated construction or work zone;
b. Whether the department of transportation guidelines involving notice and signage were properly implemented in such work zone; and
c. Whether the investigating officer had probable cause to believe the person's negligent acts or omissions contributed to his or her vehicle striking a highway worker.
(3) The department of revenue administrative adjudication to reinstate a driver's license that was revoked under this subsection, and any evidence provided to the department related to such adjudication, shall not be produced by subpoena or any other means and made available as evidence in any other administrative action, civil case, or criminal prosecution. The court's determinations issued under this section, and the evidence provided to the court relating to such determinations, shall not be produced by subpoena or any other means and made available in any other administrative action, civil case, or criminal prosecution. Nothing in this subdivision shall be construed to prevent the department from providing information to the system authorized under 49 U.S.C. Section 31309, or any successor federal law, pertaining to the licensing, identification, and disqualification of operators of commercial motor vehicles.
