This video, titled “Codysur Group Truck runs driver off the road,” is a great example why it’s not a good idea to stay in a truck’s blind spot.

In the clip a tractor trailer merges into the right line and unknowingly knocks the recording car driver onto the road’s shoulder.

Now we’re not defending the truck driver’s actions in this one — he should have been more aware of his surroundings. But it’s also an important lesson for all car drivers to know.

Staying in a truck’s blind spot is like walking through a war zone, where everyone’s blindfolded.

It’s just not a good idea.
