The following information is provided for the enlightenment of all drivers. The information comes from a brochure prepared by the Tennessee Highway Patrol and the Tennessee Department of Safety. There is no copyright notice on the brochure, but I want to give credit to whom it is due for this material.
You can help promote WRECKless driving by knowing the "No-Zone". The No-Zone represents danger areas around trucks where crashes are more likely to occur.
When cars cut in too soon after passing, then abruptly slow down, truck drivers are forced to compensate with little time or room to spare. Because it takes longer to pass a large vehicle, you should maintain a consistent speed when passing and be sure you can see the cab of the truck in your rear-view before pulling in front.
When a truck is backing up, it sometimes must temporarily block the street to maneuver its trailer accurately. Never pass close behind a truck that is preparing to back up or is in the process of backing up. Remember, most trailers are 8 1/2 feet wide and can completely hide objects that suddenly come between them and a loading area. So if you try to pass behind the truck, you enter a (No-Zone) blindspot for you and the truck driver.
Unlike cars, trucks have deep blindspots directly behind them. Avoid tailgating in this No-Zone. The truck driver can't see your car in this position and your own view of traffic flow is severely reduced. Following too closely greatly increases your chance of a rear-end collision with a truck.
Trucks have much larger blindspots on both sides of their vehicles than passenger vehicles (cars). When you drive in these blindspots (No-Zones) for any length of time, you can't be seen by truck drivers. If a commercial driver needs to change lanes quickly for any reason, a serious crash could occur with the vehicle in the No-Zone.
Truck drivers sometimes need to swing wide to the left in order to safely negotiate a right turn. They cannot see cars directly behind or beside them. Cutting in between the commericial vehicle and the curb or shoulder to the right increases the possibility of a crash.
Don't hang out in the NO-ZONE!
