What is the difference between imprisonment and a fine in a motor vehicle accident case?

Ariz.Rev.Stat.Ann. Sec. 13-603(D) (1978). Chapter 8, in pertinent part, provides that the court may order that all or any portion of a fine be allocated as restitution, provided the offense resulted in death, physical injury or economic loss to the victim. Ariz.Rev.Stat.Ann. Sec. 13-803(A) (1978). Read together, the two statutes authorize the sentencing court to impose both imprisonment and a fine, which can be ordered as restitution. Because the Arizona legislature provided for both punishments, the double jeopardy clause is not implicated. Whalen v. United States, 445 U.S. 684, 688 (1980).
