Speeding tickets before getting CDL-A

How old does a speeding ticket have to be before it won't be an issue in getting a CDL-A? I have a speeding ticket from August 2019 (almost 5 years). I got it on a rural Nevada highway and the cop told me he was going to give me a type of ticket that would not be reported to my insurance.

The ticket he gave me said:
Posted: 70 mph
Actual: 83 mph
Cited: 75 mph

Will this be an issue if I want to get a CDL-A?

 

No, I was on vacation. I went to Shelter Cove California for several days, a mostly vacation home town in one of the most remote areas of the state. Incredibly scenic. One of the nicest places I've ever been. I stopped in Lake Tahoe after that and got the ticket on the way to Ely. It's nothing but desert and long stretches of highway out there. A speed limit of 70 mph seems a bit low for that area. Coming around a turn I saw an oncoming cop, slowed down right away but he had already picked up my speed on his radar.

 

I do have older stuff on my driving record. Most of it is pretty old and not serious, mostly minor traffic violations, although I did get a DUI in 1986. I was also charged with a DWAI in 2002 but the charge was dropped by the prosecutor because the breathalizer showed that I was under the legal limit, but the cop gave me the ticket anyway.

Do you think any of that older stuff would prevent me from getting a job today?
