"I have to ask....... What kind of cars are the Canadians driving these days? I think my wife's Kia could get past those trailer skirts."
Good question ...there are so many small cars out there nowdays, both domestic and imports and Canadians drive them all it seems. You wouldn't catch this body in any of them. I like protection and drive a Suburban for that reason and others.
Everyday we hear about highway accidents where cars are crushed under flatbeds or trailers of some sort. Not a nice way to go if you ask me.
Those panels look flimsy but do deflect vehicles and obstacles away from the wheels of the trailers. They have some strength built in so I think your wife's Kia might just bounce off rather than snowplow underneath the wheels. Also a lot of wrecks are seen with vehicles rear-ending a transport and going up underneath. The front ends are so low it would be hard to avoid.
And next July1 we are getting pot legalized up here so might see more stoned drivers under those big rigs.
