That being said I also agree with you as I know that you agree with me that courtesy on the road is a requirement of all.
No worries...Most truckers are as courteous as they can be while still trying to operate a profitible business. Some of their actions make typical drivers wonder what the heck they are doing and don't understand that almost every odd maneuver or behavior you see from a trucker has a specific reason behind it. To the normal driver they just think the truckers are trying to make them mad.
