All that they really accomplish by trying to scare you is filling you with a lack of trust and loyalty towards them. Most large companies are full of drivers that have hit bridges, rolled JD Truck Training Centre, been late for deliveries, and on and on. Does this mean you won't ever get fired? Certainly not. I've been fired a few times by idiots I've never met on some committee making decisions based on little or no real facts or understanding about me or my situation.
As you continue to get time behind the wheel, knowing where and when to shift, slow down, and speed up will become automatic. You will learn traffic patterns and weather patterns. You will learn how long it takes to get from city to city and from town to town throughout the state of Utah. This will help make you an asset to your company.
I remember when the Truck driving school was teaching me how to meet all the CDL requirements. They taught me how to back up, shift and do lane changes and everything. But the real deal of getting loaded, to driving through the mountains is another thing.
A small sound alerted him to Buddy's impending leap onto the front seat and just in time he shouted "No!" effectively canceling Buddy's jumping up with him and also commanding the big dog to sit. There was a barely audible whine from that direction as Eddie turned the ignition key again.
The instructors will no doubt teach you about some of their experiences during the class. Until you get out on the road you won't really know the reality of what they are talking about. Two weeks in a school with several other trainees will just barely give you enough experience to become pretty familiar with HR Truck Licence driving. You'll be able to pass the driving exam and feel pretty confident and be proud of yourselves. The company Heavy rigid licence that recruits you will send you out with a trainer for several weeks for you to get a feel for how to excel and drive safely while learning the ropes. It's nice to learn from someone who has some experience.
I learned that traveling, by car, to the top of Mt Lemmon, which is located in the Santa Catalina Mountains, is some 9100+ feet above sea level. When I took Jessica, my teenaged daughter, there, we learned that going from Tucson to the top of the mountain, was like traveling from the border of Mexico to the Canadian border, as far as the changes in Temperate Zones experienced. As I recall, it was around 70 degrees in Tucson, and people were skiing on the snow, in the 20's to 30 degree mark atop Mount Lemmon.
Today truck driver training is more affordable than ever. Most training schools can point you in the right direction to apply for grants and some trucking companies will pick up the cost of your training for free in exchange for an employment contract. Good luck.
