Before you work with this carrier

• Confirm active authority. A USDOT number means the carrier is registered — it does not by itself prove active for-hire operating authority. Check the SAFER snapshot above.
• Check insurance on file. Brokers and shippers should verify current BIPD/cargo insurance before tendering a load.
• Review the safety rating and out-of-service status, especially for higher-risk cargo.
