As I was driving to work this morning, for whatever reason, I began to think about our traffic systems … specifically about the right-hand and left-hand drive systems. I began researching the issue on the web and discovered that the origins of these systems began as far back as Roman times.

Several hundred years ago, the logic of traveling on the left side of the road was pretty clear. Most people are right-handed and by traveling on the left side of the road, it was easier to great people traveling in the opposite direction.

Additionally, it was easier for a person to reach and wield his sword should there be a confrontation.

Other things that made travel on the left side of the road logical was that a person driving a wagon or coach, also being mostly frequently right-handed, could hold the reins in his left hand and utilize a whip with his right hand without obstruction sitting on the right side

of the coach.
