#2 - Carpooling
There are a number of benefits to carpooling -- it helps decrease traffic congestion, it helps cut down on emissions, and perhaps most noticeably: it decreases the amount of cars jockeying for space in the pick-up and drop-off lanes. This might not sound like a big deal, but those are prime accident areas, both between vehicles and between vehicles and pedestrians.
Don't let the kids distract you while you're driving and keep close tabs on seatbelts and windows. When it comes time to drop them off or pick them up, use extreme caution and follow all the school's guidelines to decrease the chances you'll be one of those involved in an accident.
