Usually I see the cow and calf... and then almost hit the other calf who lingered before stepping out. I've been lucky on bikes but I came upon a cow and calf in my lane in a snowstorm and swerved completely into the other lane to avoid them which worked well until the calf charged my headlight... he got it; it got him. He been Forded. Ford needed a new radiator, hood hinge, and fewer dents.
Most critical times in Alaska for moose is in May when they all pop their calves in about a week on the premise that bears can only eat so much; therefor more calves will survive until they become mobile enough to travel. Of course dawn, dusk, and the rest of the time are ALL critical moose avoidance times. I watch for them all the time. They seem to congregate near houses and roads in the fall to avoid ravenous bears who've run out of greenery to eat but haven't denned up yet. Bears don't hang around people much unless you're talking trash, it's an attractant. Occasionally someone will hit a bear on a road but the moose are a constant hazard.
On the common sense side don't poke, pet, or go stand next to a moose. As calm and bovine as they may seem they can move much faster than you can. Once they attack they're very thorough. I've seen tourists, and neighbors, do some really stupid stuff for a better picture.
