Fleet Safety Tip of the Week

November 09, 2011

This week’s driver safety advice, provided by the Tennessee Department of Safety, concerns the "No-Zone" for large vehicles. You may want to pass this along to your drivers as a friendly reminder.

Many motorists falsely assume that drivers of trucks and buses can see the road better because they sit twice as high as the driver of a small vehicle. While trucks and buses do enjoy a better forward view and have bigger mirrors, they have serious blind spots into which a small vehicle can disappear from view.

The No-Zone represents danger areas around trucks and buses where crashes are more likely to occur.

1. The area approximately up to 20 feet directly in front of a large vehicle is considered a No-Zone. When small vehicles cut in too soon after passing or changing lanes, then abruptly slow down, trucks and buses are forced to compensate with very little room or time to spare.

2. Unlike small vehicles, trucks and buses have deep blind spots directly behind them. Avoid following too closely in this No-Zone. If you stay in the rear blind spot of a large vehicle, you increase the possibility of a traffic crash. The driver of the bus or truck cannot see your vehicle and your view of the traffic ahead will be severely reduced.

3. Large vehicles have much larger blind spots on both sides than cars do. When you drive in these blind spots for any length of time, the vehicle's driver cannot see you. When passing, even if the vehicle's driver knows you are there, remaining alongside a large vehicle too long makes it impossible for the driver to take evasive action if an obstacle appears in the roadway ahead.

4. Truck and bus drivers often cannot see vehicles directly behind or beside them when they are attempting to safely negotiate a right turn. If you cut in between the truck or bus and the curb or shoulder to the right, this maneuver greatly increases the possibility of a crash in this "right turn squeeze."
