Truck Graph identifies 45 active risk indicators across Washington carriers (0.31% of the registered population), detected through pattern analysis of authority cycling, insurance filing anomalies, and known chameleon carrier behaviors. The FMCSA defines chameleon carriers as entities that "successively obtain and relinquish operating authority to evade enforcement actions" — a practice that puts shippers at risk. Additionally, 45 Washington carriers have prior authority revocations on record. Shippers should verify carrier authority status, insurance coverage, and safety ratings before every load tender using the FMCSA SAFER System or Truck Graph's instant verification tools.
