Lithuania, the EU and other countries
Poland · Russia · China · India · United Kingdom
We first study Lithuania's rules and applicable EU rules. Europe is not only the EU: the route, national law and international agreements matter for each journey. Here we compare a few selected differences.
We choose sources for their relevance and reliability: they may come from Lithuania, Poland, other EU countries, the United Kingdom, Russia or elsewhere. A source's country alone does not determine which rules apply in Lithuania. The scope and sources for each comparison are provided alongside it.
Illustrative operating points: A – 100 kW and 22 kg of fuel per hour; B – 100 kW and 25 kg per hour. Which has lower specific fuel consumption?

Point A: 220 g/kWh, compared with 250 g/kWh at point B. Both deliver the same useful power, while A uses less fuel.
Please note
These are illustrative steady-state operating data, not a test of a particular truck or a prediction of journey fuel consumption.
A simple explanation
Divide the fuel mass flow in grams per hour by the useful power in kilowatts: 22 000 / 100 = 220 g/kWh, and 25 000 / 100 = 250 g/kWh. Comparing only the lower kg/h figure would be insufficient if the power outputs also differed. This parameter differs from the vehicle's overall fuel consumption for a journey in l/100 km.
Specific fuel consumption = fuel flow / useful power.

Learning objective: Calculate and compare g/kWh, taking useful power into account. EU syllabus area: 1.1. The meaning of g/kWh on the operating map was checked. The task uses illustrative figures; 22 000/100 and 25 000/100 were calculated separately.

Question map
Understand the whole topic
Short explanations supplement the 300 questions. Choose a lesson, then return to the related questions and test your recall.
EU C / CE learning areas
The 300 questions are mapped to 14 freight transport learning areas in Annex I to Directive (EU) 2022/2561. Choose a specific skill and its related questions. Practice tasks help you prepare for work with an instructor.
Visual explanations
Five explanations help you understand motion, visibility, loads and vehicle checks. You can change values in the braking and axle-load examples.
Practical scenarios
Read the facts and decide what you would do. Then reveal the solution and compare your explanation. These are additional tasks alongside the 300 questions; no points are awarded.
Check your knowledge
Additional quiz questions are linked to the 300 study questions. After you answer, each option is explained, and at the end you will see results by topic.
Learning together and feedback

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