How Many No Zones Are Around a Semi Truck?

The Federal Motor Carrier Safety Administration, or FMCSA, has established No Zones around semi-trucks and other large commercial trucks. No Zones are safety zones around the truck that drivers should avoid when driving near one.

The four No Zones are the front, back, left side, and right side of the truck. For drivers, it is important to remember that the No Zone areas are not just limited to the sides of a semi-truck; they extend out to the sides and rear of the truck as well.

On the front of a semi-truck, a 20 foot No Zone exists from the bumper to about two car lengths ahead of it. This zone is important for drivers because trucks can take up to 40 percent longer to stop than cars due to their size and weight. The back 20 foot No Zone area is also important for drivers because trucks have large blind spots where they cannot see oncoming cars.

The left and right side No Zones extend out 30 feet from each side of the truck. This area is especially dangerous because this is where cars may cross behind a truck if they are trying to pass or get around it. It is important for drivers to remember that these zones exist and that they should not attempt to pass or cross too close in front.

In conclusion: All in all, there are four distinct No Zones around a semi-truck: one 20 foot zone in front and behind of a truck, as well as two 30 foot zones on either side. Drivers should be aware of these zones when driving near large commercial vehicles so that they can stay safe on the road.
