There are lots of Trucking apps out there but this is the first one that will actually teach you what it takes to back up in the real world. The more you play the quicker you are going to be able to figure what you will need to do in a real Truck. I have nearly two decades of driving a truck and have backed up over 60K times and have though over 150 students as a company trainer. I know what struggles new drivers go through having to learn how to back up with a real truck and trailer and how scary it is. This takes the guesswork out and gives you the confidence to back up into any dock.

CDL Training
I have set up CDL training levels for lots of different size trailers and all the scenarios that you will be tested on. The trailer sizes are 28, 35, 48, and 53 feet long and each level is custom-built for the trailer size.

Hard Campaign Level
When you start to get more comfortable with the normal campaign you can try your skills on the same levels but with Blind Spots turned on. When you are driving on these levels you are only going to be able to see what you would if you are sitting in the cab. But there is a "Get Out And Look" button that you can use that will turn off the Blind Spots so when you are unsure if you are going to hit something.

Gesture Turning
To turn left or right all you have to do is slide your finger to the left or to the right on the bottom 25% of the screen. You don't even have to start from the center, just slide your finger in the direction you want it to turn. Sliding your finger from one side of the screen to the other will let you turn your steers from one side to the other, but be careful if you have the steers pointing all the way to the right and you want to have them all the way to the left, sliding from the center of the screen will only point the steers straight so you will have to slide your finger more. The slider is just an indicator if you want to see where your steering is, you can always look at the steer tires or the steering wheel at the top of the screen. A lot of the time I will look at the steering slider to see that I am pointing my steer perfectly straight before I start to back up and then just pay attention to my trailer and the green lines.
Speed
The rest of the screen is for controlling the speed. Anywhere on the top 75% of the screen can you slide your finger up or down to move forward or reverse. If you want to stop all you have to do I double-tap anywhere on the screen and you will screech to a stop.
You can zoom in and out by using two fingers and pinching, and you can pan around the map too by moving your two fingers around the screen.
You will find that there are RED, Green, and blue lines that are on the truck and trailer. There is a REALLY big reason for this. Without these lines, I think that the game would be unnecessary hard. The red line shows you the direction that the back of the trailer is pointing towards. And if you have ever seen my videos before I started using this game to demonstrate backing, I always had RED lines showing where the trailer was pointing because in the real world all you have to do is look in the mirror or stick your head out the window to see that. I have discovered that it is very hard to see that without the red line in a game that is a top-down view (aerial view). The green lines are to show you how straight your truck and trailer are at. Just like in the real world all you have to do is look in your mirrors to see if you are straight or not. The blue line not as important but I added them anyway because a top-down view does not always give you a good indication of where you are driving towards when your steers are pointing straight. I do love my lines.
