About Fuel symbols and the 1-minute rule: which statement is correct?
- If you accidentally tanked the wrong fuel, you may start the engine briefly to move the car out of the way.
- Square is the symbol for petrol, circle is the symbol for diesel.
- ✓ This is an environment-focused efficiency tip, not a legal duty (legal_ref: n/a).
- These fuel symbols (circle/square/diamond) only apply at Dutch filling stations.
Correct answer: This is an environment-focused efficiency tip, not a legal duty (legal_ref: n/a).
Explanation
This is an environment-focused efficiency tip, not a legal duty (legal_ref: n/a). The 1-minute threshold is a guideline to limit unnecessary emissions, not an offence if not followed
Why learners get this wrong
- The instruction has no exception: do not start the engine if you tanked the wrong fuel. Even 'just briefly' already lets the wrong mixture circulate through the lines and injectors
- The EU fuel symbol assigns the shapes exactly the other way round: circle = petrol, square = diesel, diamond = gas/hydrogen. Since 2018 this applies everywhere in Europe
- The symbols come from Directive 2014/94/EU and have applied EU-wide since 2018, at every pump in every member state, not only in the Netherlands
