Is suspension of driving privileges an effective way to collect unpaid fines?
No, according to a recent study of efforts to enforce monetary judgments in a Milwaukee municipal court and to a national organization with expertise in traffic safety. The Justice Initiative Institute reviewed non-criminal, municipal cases from 2008-2013 in which the Milwaukee court had ordered the detention of defendants for not having paid fines.
Not surprisingly, the report shows that most people who fail to pay fines have little if any income (a majority of those detained were unemployed). Therefore, although the prospect of sanctions might encourage payment by a population with greater financial resources, the use of incarceration for non-payment ends up costing the City of Milwaukee more than any additional amount of fines collected.
