first of all im new to this forum and i think it's full oif knowledge and i love it. recently i went out with a trucker friend of mine just to observe and get the feel of what i was about to get into.while traveling in atlanta around 4 a.m in the morning we approached a truck driving real erratic.as we got closer to the truck i noticed it was a driver from arnold trucking.this guy was all over the road swerving and barely missing cars by less than 2 feet.he managed to get in the middle lane but could not hold the truck in the lane for only a few seconds before he started to swerve again and again.my buddy got on the c.b radio and stated "arnold wake up you gonna hurt someone,if ya sleepy pull over".he done this several times but the driver never responded.i thought this was so strange and odd because i always noticed that most truckers were very safety oriented.i was really shocked.i dont know what happened to him after we passed him my buddy stated we are getting away from him...
