Hello all,first of all great site. I drove for werner for a year and when i went through oreintation i didnt have to take a road test,only experinced drivers have to take a road test for oreintation.I hope this helps some.

Some of you might have seen my other post. Been out of a truck for awhile so I'd be very rusty if required to take a driving test.
If you are being hired on as an "experienced" driver, you will take a short "round the block" driving test. If you are hiring on as a "trainee" or "student", you will go out with a trainer for whatever time they require for you (drivers without recent expereince will not have to stay with a trainer for the full time) then after training you will be dropped off at a "full service" terminal and be tested out. This will be a pre trip and a driving test.
BTW, what are the advantages of the Super 10? Drove a standard 9/10 speed in school.
I like the "Super Ten" they are a "lazy man's" transmission, I wrote this description a while back, it covers the shifting of the super ten..hope this helps!
The ten speed transmission is very common and the chances are that if you spend any time in the industry, you will probably end up driving a truck equipped with this transmission. For people who have never driven a truck the easiest way to describe the ten speed transmission (and really most other multi-geared truck transmission) is basically two five speed transmission “stacked” on top of each other. You basically move the gear shift through the same places in the gear pattern twice. You have a low range which has the LOW reverse, 1st (low), 2nd, 3rd 4th, and 5th. The gear shift has a switch called a “range selector” which allows you to shift up to the “high range” of gears which are in the same locations in the gear pattern as in the “low range“. You shift through gears 1-4 and when in 5th you flip the “range selector” up or forward. When you pass the gear shift lever through the neutral position heading to the slot where 6th gear is, the transmission shifts into the “high range” and you can shift into5-6-7-8-9 and tenth. You shift into the same place in the gear pattern, you just have to switch the transmission from the lower range to the higher range.
The first tip is to try and learn what gears you will be able to keep the engine in the "operating range". Usually the “operating range” for most truck engines is somewhere between 1000 - 1500 RPM's. An example is that in first gear the MAXIMUM SPEED in that low gear is about 4 MPH. The best way to figure this out is to learn to read and rely on the tachometer to tell you when you need to up shift. There is really no way to “quickly” shift a truck neither up nor down. This is a skill that most people must acquire when learning to drive trucks. In cars you can pretty much drive them anyway you like to! In trucks they will almost not allow you to drive them incorrectly! You learn to watch the tachometer and your road speed and pick the correct gear for road conditions or the posted speed limits. Upshifting is a relatively simple process and new drivers pick up that skill pretty rapidly.
You will learn to shift “progressively”. Progressive shifting simply giving the engine only enough fuel (RPM’s) to complete the shift to the next higher gear. This usually means that to get into the next higher gear you must progressively give the engine more fuel (RPM’s) to complete each up shift.
Here’s an example, You can start most lightly loaded or empty trucks moving in third gear, You are at a dead stop and the engine is idling at 700 RPM’s. In 3rd gear You slowly release the clutch and start off watching the tachometer and raise the RPM’s to 1000, QUICKLY tap the clutch and move the shifter into neutral, then QUICKLY tap the clutch again and move the gear shift to 4thgear. Raise the RPM’s up to 1100 QUICKLY tap the clutch and move the shifter into neutral, then QUICKLY tap the clutch again and move the gear shift to 5thgear. Move the range selector to high! Nothing will happen until you actually move the gearshift lever into the neutral position.
Raise the RPM’s up to 1200 QUICKLY tap the clutch and move the shifter into neutral, then QUICKLY tap the clutch again and move the gear shift to 6thgear
Smoothness only comes with practice and the only real difference in experienced people and new people is that we can smoothly fix our mistakes quicker than you can.
When shifting down in a short distance, can one skip gears on a 10 speed?
Yes, you can skip gears in most trucks while downshifting. The key here is that you must know at what rpm’s you start the shift. ALL downshifts can be made exactly the same. This is almost just a simple math problem. A regular downshift is done the same by bringing the rpm’s down to a set or certain number and starting the downshift. This can be done the same way for every shift. In most trucks there is a certain rpm difference between gears. For this example we’ll use 300 rpm’s between the gears.
So if we want to downshift one gear; Watch the tachometer, and drop the rpm’s down to 1000 rpm’s. The instant that the tachometer drops to 1000 rpm’s, tap the clutch and move the shifter into neutral, Quickly raise the rpm’s by 300, (1000 rpm’s + 300 = 1300 rpm’s) Tap the clutch and move the shifter into the next lower gear. (like 8th to 7th) That’s an example of a regular downshift, to “skip gears” you have to be able to raise the rpm’s enough to double the number of rpm’s required for one gear. So if it takes 300 rpm’s to drop one gear, it will take 600 rpm’s to drop two gears and If you want to 900 rpm’s to skip two full gears. You will have to drop the rpm’s a lot lower to actually raise the rpm’s that high, but it can be done.
So if we want to downshift two gears; (also known as “doubling down” Watch the tachometer, and drop the rpm’s down to 1000 rpm’s. The instant that the tachometer drops to 1000 rpm’s, tap the clutch and move the shifter into neutral, Quickly raise the rpm’s by 600, (1000 rpm’s + 600 = 1600 rpm’s) Tap the clutch and move the shifter into the second lower gear. (like 8th to 6th)
There is a problem if trying to drop too many gears. There are limitations to how high you can actually raise the rpm’s. Most truck engines are limited to the rpm’s that they can reach. If you try to down shift and your rpm’s are not low enough, you may not be able to rev high enough to get into the next lower gear. If there is an rpm limit set at 2100 rpm’s and you try to downshift two gears, but you only drop the rpm’s down to 1600 rpm’s, there is now way to raise the rpm’s up high enough to get the truck into gear. 1600rpms +600 = 2200 rpm’s. This is the main reason that people are taught to be in the proper gear before descending steep grades. If your brakes start to fail and you take the truck out of gear, there is now way to rev the engine high enough to get it back into gear!
