One in five carriers are at risk of an intervention under the Federal Motor Carrier Safety Administration's new methodology for calculating safety measures under CSA 2010, according to an analysis of safety performance by Rair Technologies.
The analysis also found that carriers are most likely to be deficient in the Fatigued Driving Behavior Analysis and Safety Improvement Category, or BASIC, regardless of size.

Rair recently analyzed safety performance of more than 60,000 fleets to look at the impact of the new CSA 2010 SMS methodology.

The technology services provider found that under the new methodology, the smallest fleets, one to five vehicles, saw their risk of intervention increase from 10 to 15 percent. Meanwhile, the largest fleets, with more than 500 vehicles, saw their risk drop from 72 to 42 percent.

While fleets are most likely to be deficient in Fatigued Driving, Vehicle Maintenance and Unsafe Driving were the second and third most problematic areas, Rair said.

In addition, the likelihood of being deficient in the Crash Indicator and Unsafe Driving BASICs decreased significantly for all but the small fleets, with 15 and fewer vehicles. The smallest fleets are significantly more likely to be deficient in these two BASICs. The risk of deficiency in the Improper Loading BASIC fell significantly across all fleet sizes.
