How do employers count "1 year experience"?

From the time I started driving in the company parking lot?

From when I got my permit and started cruising around the block?

When I started driving to and from shippers?

or...

When I got my CDL?

 

Pretty sure its last day of orientation

 

When did that happen

 

One year from your date of hire, just like any other job.

 

My hire date and tractor-trailer experience don't exactly line up, though.

I was hired this past April, spent my first week as just a mover riding with other drivers.

Week 2 I was driving Class C straight trucks (had been doing this for four years prior at previous job anyway).

Started driving in the yard later that month.

Got my Class A permit in May.

Started actually driving to and from shippers in August.

Got my Class A license on October 26.

 

I went to mister p driving school and they actually counted the day I got my license as my year start date.

 

I stayed the year to have my schooling paid for in full.

 

All my training has been on-the-job so I don't know if prospective employers count differently than a trucking school does.

 

And who else in the world is going to know, or care, about that? No one! Don’t overthink it Freddy.

 

I mean at a minimum they'll be looking at my CDL issue date, right? Can I use my permit (which I held onto) and let them know I started driving then?
