Big trucks have big blindspots - and to stay safe, you should avoid them. The No-Zone refers to blind spot areas around big trucks, where crashes are most likely to occur. Trucks have deep rear blind spots. If you can't see the truck mirrors, the driver can't see you. Stay well back of big trucks to avoid rear end collisions.
Trucks have large blindspots on both sides.
If you stay in these blind spots, that can mean trouble if the trucker decides to change lanes. Truckers must sometimes swing wide to the left in order to make a right turn. They can't see cars directly behind or beside them. If you cut in between the truck and the right curb, you might cause a collision. When you pass a big truck, make sure you can see the entire truck cab in your rear-view mirror before pulling in front.
