QUESTION 011Not studied yet

A loaded truck is climbing a hill: road speed and engine speed are falling, and the current gear no longer provides enough pulling power. How should you respond?

General principles • transmission operationCompared with sources

Answer

Select a suitable lower gear in good time, or the manufacturer's specified automatic transmission mode, so that the engine operates in a range suited to the load. Maintain a safe speed and smooth control.

Please note

Do not exceed the manufacturer's permitted engine speed when changing gear; use specific automatic transmission modes according to its instructions.

A simple explanation

A hill and greater mass require more tractive force. A lower gear can increase the torque delivered to the wheels, although road speed will be lower. Simply pressing the accelerator harder does not solve the problem when the current operating conditions do not provide enough pulling power.

REMEMBER

Not enough pulling power? Assess the gear, load and engine speed.

Learning objective: Select appropriate transmission control when pulling power becomes insufficient on a climb. EU syllabus area: 1.1. The manufacturer specifies consideration of engine speed, mass, gradient and torque demand; increased torque in a lower gear is based on the relationship between gearing and power.

Learning together and feedback

Try it together in 25–30 minutes

For an instructor and a small group: choose one C/CE freight transport topic in the Lithuania and EU context. Use your own devices, including a phone and a computer.

  1. 3 questions. In ‘Recall’ mode, first answer in your own words, then read the explanation and mark what needs more review.
  2. A lesson and a diagram. Discuss what they explain and which conditions matter.
  3. One scenario. Decide before revealing the solution. Explain the reasons for your chosen action.
  4. A few quiz questions. Read the explanation for each option. You can finish the quiz early; the remaining questions will be marked as unanswered.
  5. Discussion. Everyone names one useful point and one thing that needs correcting.

How can you share or suggest a correction?

You will find the question link and feedback field below this section. Lessons, diagrams and scenarios have their own ‘Copy link’ button. ‘Suggest a correction’ helps you prepare a note with the specific link and version label. Copy or download the text and pass it on for review.

Discuss: is it easy to find an answer and return to the question? Can you explain the reason and the limits of the rule's application? Which sentence is misleading? Flag any significant legal or safety uncertainty for checking before using the material.
