Is 'Student Driver' code for something?

And even a fully-trained school bus driver is a “student driver”.

Well played; that one hadn’t even occurred to me.

Slightly, but not completely off topic, but I thought it interesting:

I follow a YouTube channel called “Fridays With Frank” which typically posts once a week (on Friday) and recounts a traffic stop by Pinal County Sherrif’s Deputy Frank Sloup.

Frank usually drives a sporty unmarked police car that has a Student Driver sticker on it. I seem to recall that he once mentioned another officer placing it as a joke.

More off topic, but I just recently bought an impact driver and this thread made me consider taking the text “IMPACT DRIVER” from the package label and setting it in my rear window.

Or you could put one of these in your window.
