What is the best time of year, and best time of day to spot a moose on the side of the highway?  My experience is that Springtime is the best time of year to have a good chance of seeing the big brown reindeer. When the snows melt, the salt left behind from plow trucks and sanders provides an appetizing lick for the good ol’ moose. As well, as spring lingers on, and the blackflies and mosquitos come out, the moose like the highway corridor as a getaway from the horrendous onslaught of tormenting bugs. In terms of the best time of day, the early morning and early evening hours are your best bet.  Bugs are at their most bountiful and have drive the poor animals out into the more open spaces.  Remember to have your sidekick scanning the sides of the highway ahead to see if there are any moose present. If one is standing there, be sure to slow down and enjoy the good look.  Slowing down to pull over may be a hazard so be on the watch for cars behind and infront of you.  No need for an accident.
