Commercial Driver's License

Category - Standard Driving

When driving a commercial vehicle with a manual transmission, drivers should do what when they need to upshift?
  1. Float the clutch
  2. Double clutch
  3. Single pump clutch
  4. None of the above
Explanation
Answer: B - When driving a heavy commercial vehicle that needs to go into a higher gear, drivers should double clutch to get the vehicle into gear. Very experienced drivers may be able to upshift without using the clutch, but most drivers would do well to double clutch. Applicants for the CDL should always double clutch when taking their driving test as examiners will often look for this in those being tested.
