What do satisfactory, conditional, and unsatisfactory safety ratings mean under 49 CFR 385.3?

Short answer

A satisfactory safety rating means a motor carrier has adequate safety management controls, a conditional rating means controls are lacking, and an unsatisfactory rating means controls are inadequate to the point of risking safety.

The rule says

1. "Satisfactory safety rating means that a motor carrier has in place and functioning adequate safety management controls to meet the safety fitness standard prescribed in 385.5." (49 CFR 385.3)

2. "Conditional safety rating means a motor carrier does not have adequate safety management controls in place to ensure compliance with the safety fitness standard that could result in occurrences listed in 385.5 (a) through (k)." (49 CFR 385.3)

3. "Unsatisfactory safety rating means a motor carrier does not have adequate safety management controls in place to ensure compliance with the safety fitness standard that could result in occurrences listed in 385.5 (a) through (k)." (49 CFR 385.3)

In plain English

These ratings reflect how well a motor carrier manages safety, based on factors like compliance with regulations, accident history, and vehicle maintenance. A satisfactory rating indicates a carrier has effective safety controls in place, while a conditional or unsatisfactory rating suggests problems that need correction. An unsatisfactory rating can lead to a carrier being prohibited from operating.

What to do

• Review your safety management controls to ensure they meet the safety fitness standard.
• Address any deficiencies or violations that could lead to a conditional or unsatisfactory rating.
• Maintain accurate records of your safety performance and compliance with regulations.
• Be prepared for a compliance review or safety audit to demonstrate your safety management controls are adequate.
