I feel like this would be great advice if "CDL" was unambiguously googleable. This might be regional but I have no idea what this is meant to mean.
Kagi was founded in 2018, and I just gave you an example of a shared reality between those two search engines. For your information, the first result of both searches was the same as well.
Obviously given I'm paying for Kagi I believe it has some value over Google, but there's still a pretty significant core of searches that it doesn't really matter which engine you're using.
Thanks to all who responded to the post though. I can see this answer in my results, just further down the list than most people are suggesting due to whatever targeting I'm receiving.

Where I’m from at least, commercial drivers license fills the first two pages.
