Not really. As a percentage of the total trucks in their fleet, small carriers could have a higher percentage of violations than mega carriers. But I don't think small carriers do a worse job of maintenance than larger carriers. In fact, most small carriers that I know try to keep a close eye on their trucks. I also know some large carriers who skimp on some of their maintenance.
I think the main reason for the groupings is because of the way violations affect smaller carriers as compared to large carriers. For instance, if a 2 truck carrier has 1 out of service violation then they have 50% out of service. If a carrier that has 2,000 trucks has 1 out of service then it would barely show up as a blip. For it to have the same impact on the carrier with 2,000 trucks, they would need to have 1,000 trucks put out of service. It makes sense to put carriers into peer groupings.
