So in training the instructors hammer it into your head to double clutch and I know I need to for the test but how many of yall actually double clutch when you're on your own?

Double Clutch:

To engage and then disengage the clutch twice for every gear change.

When double clutching you will push in the clutch, take the gearshift out of gear, release the clutch, press the clutch in again, shift the gearshift into the next gear, then release the clutch.

This is done on standard transmissions which do not have synchronizers in them, like those found in almost all Class A trucks.

When I drove for Schneider, once I learned to float gears , I usually only clutched in cities or towns.

Float Gears:

An expression used to describe someone who is shifting gears without using the clutch at all. Drivers are taught to "Double Clutch" or press and release the clutch twice for each gear shift. If you're floating gears it means you're simply shifting without using the clutch at all.

Double Clutch:

To engage and then disengage the clutch twice for every gear change.

When double clutching you will push in the clutch, take the gearshift out of gear, release the clutch, press the clutch in again, shift the gearshift into the next gear, then release the clutch.

Funny thing Mike; my CDL school instructor would not even allow us to practice double clutching - we only floated gears and skip shifted. Typically, we would start in third, float to 5th, 7th, 8th, 9th, 10th, then back down the same way.

The 3rd party examiner for the road test wasn't exactly thrilled, but as long we demonstrated control, he was okay with it. I'm hoping it's okay with my trainer when I actually accept an offer. I'm sure I can double clutch just fine, but have had zero experience doing so.

CDL:

Commercial Driver's License (CDL)

A CDL is required to drive any of the following vehicles:

  • Any combination of vehicles with a gross combined weight rating (GCWR) of 26,001 or more pounds, providing the gross vehicle weight rating (GVWR) of the vehicle being towed is in excess of 10,000 pounds.
  • Any single vehicle with a GVWR of 26,001 or more pounds, or any such vehicle towing another not in excess of 10,000 pounds.
  • Any vehicle, regardless of size, designed to transport 16 or more persons, including the driver.
  • Any vehicle required by federal regulations to be placarded while transporting hazardous materials.

There are very few double clutching drivers out here in the real world, but there are a few. I've never really figured out why, but they do exist.

The newer automatic transmissions have come a long way, no doubt about that. Me personally, I've always loved to row. I guess if I work for a company that only had auto I'd be ok with it but there's just something about shifting that reminds you, this is a real truck.

Exactly. No reason to touch the clutch unless you're coming to a stop or you've gotten into a bit of a bind with it.
