Warning Warning Warning, no mater how much you want to save fuel don’t draft a big rig. I drove an 18 wheeler for over 20 years and the one accident I witnessed still haunts me today. Car was drafting a semi doing 70 miles per hour. the car was about 40′ or 50′ off the ICC bar (bumper) of the truck. the truck blew a trailer tire. the tire tread went through the right side windshield of the auto decapitating the drivers wife in the front seat and his 6 year old daughter in the right side back seat. I was about a half a mile behind the accident when it occurred. I was the first person on the scene and when I reached the car the driver was sitting in shock with his wife’s head in his lap!Don’t tailgate a truck, don’t draft a truck period!!!!
