HOV Lane

If you're in another city and you see a highway lane, typically the leftmost, that's not very crowded, it makes total sense to slide over to it.  But if it's marked as an HOV (High-Occupancy Vehicle) lane, make sure you comply with its rules, usually that you have at least one passenger aboard, but read closely, as an expensive ticket awaits rule-breakers.  While a baby counts as an occupant, it's unlikely that police officer will be able to see them tucked in the back seat of your car before you're pulled over and your travel interrupted.  But watching other folks fly by while you're in a traffic lane just poking along is really frustrating.  Don't fall for the temptation.

So why don't we have them in Dayton?  Because we don't have that special kind of crazy traffic, of course.
