The primary purpose of the Weight Enforcement program of Motor Carrier Compliance (MCC) is to protect highway system pavement and structures (bridges) from excessive damage due to overweight and oversize vehicles. Troopers enforce state and federal laws and DOT rules that regulate the weight, size and registration of vehicles operating on the Florida's highways.

The state's weight and size limits were established to prevent heavy trucks from causing unreasonable damage to highway systems and thereby protect the public's investment in these roadways. OMCC's Weight Enforcement program uses sworn law enforcement officers to enforce vehicle weight, size, fuel tax and registration requirements. Law enforcement officers patrol the state's highways and use portable scales to weigh trucks that do not pass fixed scale facilities.
