How Concerned Should I Be About What Happened To My Car? [View All]

[THUNDER HANDS]

Yesterday as I was coming home from work I was pulling into my parking spot on the street in front of the sidewalk. There's a big pile of snow at one end from where I dug my car out. When I pulled into the spot, I threw the car in reverse to get closer to the curb.

I must have hit the snow bank doing that, because when I got up this morning to leave for work I saw that my one of my tail pipe's was frozen solid, packed with snow that had turned to ice.

Am I in any danger of carbon monoxide poisoning? One tailpipe still works, but the other is completely clogged. I drove to work with no problem (I'm still alive) but I'm curious as to whether it's dangerous to keep driving around with one pipe clogged.

Any car experts out there know was the risk is with this?
