Answers: 1a: Yes you can. 1b: Never do that, it's illegal. 2: The system is different.

Yes you can double clutch a car or pickup truck. Only smaller (than a semi's) transmissions have gears called synchromesh that makes the grinding disappear, so the fancy footwork is not necessary.

Coasting in neutral is both illegal and can get you and/or others killed. You will, or should, learn about slick roads on hills. The basic idea in this situation is you manage you're speed so that you rarely need to slow down, because you aren't going fast on those hills. Read my post about "sleigh ride" in the topic Driving Truck In Bad Weather ? Snow, Rain, Ice.

The "Automatic Only" endorsement is only for a CDL license. See my first answer here about synchromesh gears. It's not a problem for four wheelers.

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.

SAP:

Substance Abuse Professional

The Substance Abuse Professional (SAP) is a person who evaluates employees who have violated a DOT drug and alcohol program regulation and makes recommendations concerning education, treatment, follow-up testing, and aftercare.

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.

HOS:

Hours Of Service

HOS refers to the logbook hours of service regulations.

You can practice the movement of double clutch in a car. Not quite the same and a little buckey at first but the movement can be learned. So when you drive a manual car you dont put it into second gear when turning? The idea of downshifting is essentially putting into lower gear at a higher RPM to utilize the braking effect of the engine. In a manual car if turning I put it in second gear let off gas to slow before the turn then accelerate midway to maintain full control on corners. Same as going downhill if driving in fifth and start downhill I shift to fourth then potential third gear and letting the RPMS rise to keep speed under control. Why would you coast down a mountain? Another plus if winter driving if you break traction in snow or ice simply depress clutch cutting power to wheels so they can naturally roll and regain control. Please leave it in gear going downhill when you let of gas it naturally slows you down.

Coasting with the truck in neutral is illegal and extremely dangerous. You may get away with putting it in neutral and using the brakes down a hill in a car. Try that in a truck on a major hill and you will likely kill yourself and some innocents in a car in front of you.

Many people who drive manual cars don't actually know how to drive a manual, but can get away with it since the vehicles are so light. They therefore never learn how to downshift. Learning to downshift is not an option in a truck. You absolutely must know how to properly downshift.

10-4 was wondering. In a truck that is scary a/f to lose gear period. Let alone on grade. Thanks for clarification.
