Which of the following is a cost-saving measure to limit uninsured losses?

Safe driving around the lot is a proactive approach to reduce the risk of accidents and damages, which helps in limiting uninsured losses. By emphasizing safe driving practices among employees and customers alike, a rental agency can minimize incidents that may result in uninsured claims or costs associated with vehicle repairs, liability, and increased insurance premiums.

This focus on safety can directly impact the financial health of a business by reducing potential losses that would otherwise not be covered by insurance. In contrast, the other options relate to strategies that might not directly influence unexpected losses. Offering discounts and expanding rental locations could potentially increase revenue but may not necessarily address the issue of losses, while increasing the fleet size might lead to higher operational costs without necessarily improving safety outcomes.
