If a city enforces commercial motor vehicle safety standards, what can they do with the fines collected?

The correct choice highlights a specific regulation regarding how fines collected for enforcing commercial motor vehicle safety standards can be utilized. When a city imposes fines related to these safety standards, it is permissible for them to retain only a portion of the collected fines, which cannot exceed 110 percent of the actual expenses incurred during the enforcement and administration of these safety standards. This restriction ensures that local governments can cover their operational costs while also maintaining accountability and preventing excessive profit from enforcement actions.

Under this policy, cities are incentivized to use the financial resources efficiently and directly related to the maintenance of safety standards, rather than allowing a scenario where fines could be simply used as a revenue generator or for unrelated projects. This provision also reinforces the principle that funds from fines should ideally support the objectives they were originally intended for, promoting transparency in local governance.
