Several questions about the CDL Class A.

Many practice tests on the web.
Check your local area i. e. craigslist for people or companies that rent gooseneck truck/trir combo solely for people to practice and take the CDL test.
In my area there is classaleasing.net
Minnesota CDL Truck Road Test And Testing- Class A Leasing

 

Class A for bucket trucks?

 

I did all the test before ever seeing the inside of a truck. The skills test is another story.
Think about the cost of a truck and translate it to a car.
Would you let someone with just a permit drive your Corvette around so they can learn to drive? What could go wrong? A good friend might but a O/O no way.
Find a cheap school or see if your company will pay it for you.

 

Too, a permit requires a fully licensed copilot.

 

Does the lineman school/apprenticeship not provide this training?

But yes, I passed the General Knowledge, Combination Vehicles, and Air Brakes, as well as HazMat, Doubles/Triples, and Tanker endorsements by self-studying the CDL Pass app on my phone and this free website: 2020 USA DMV CDL Practice Permit Tests. 99% Pass Rate

 

A couple of the big popular truckers forums have very good test self study helps for free. I won't mention names.

 

The State used to provide a study book, I did mine that way, it’s been a long time ago. A local Dairy, would rent the Trucks, and give road test. They were always backlogged. Ended up using my Dads Company Truck.You might find one these days, but I think you should check local community colleges.Surprised the Company doesn’t pay for you to get it. Don’t you Guys have a Electrical Workers Union? Apprenticeship programs?
