Faced with this sign on a train
Please ensure this door is alongside the platform before alighting
Is there an implication that I should act to correct the situation if the door is not alongside the platform?
I understand that the intention is that I should check that the door is alongside the platform but is the word ensure appropriate?
If a government is mandated to ensure that all children are educated then they must act if some children are not educated. Ensure in this context implies a responsibility to make sure the situation is achieved not just to check that the condition is met.
