Why not make the message and icons consistent?

Wall sign at BC Ferries terminal, Horseshoe Bay, BC

At any transportation hub there will be a plethora of signs. Go here. Don't go there. Don't even think of going there!

Most of the signs are useful and inform passenger about useful things like where ot go to pick up their baggage etc.

These two signs tell passengers with pets (dogs) and bicycles (oversize items) to board the vessel on the lower deck. There is no explanation about why the dog is leashed on one sign and unleashed on the other. Or why a bicycle is described as a bicycle on one sign and as an "oversized item" on the other.

Yes, I know the signs were made at different times, but the inconsistent message is confusing. And what business needs to go out of its way to confuse its customers?
