Does “the car slipped off the road” sound right?

It sounds a little odd. I would say the car slid off the road.

I would say the car slid off the road. "Slipped off" just seems wrong in most cases.

Yes it does!

Yes, that’s fine.

Slid. Cars slide and skid; slipping is different

You slip on a banana peel. A car slides or skids off the road. Slip isn’t exactly wrong, but seems to lack intensity when talking about a thing as heavy as a car.

Using “slipped off the road” with respect to a car would be understood perfectly, but it’s *just* off the mark. It’s so close—versus probably “slid” or “skidded”—that in a book or movie, I could see it being part of what reveals the identity of the otherwise perfect foreign spy.

I'd more likely say slid or skidded but that works.

Sounds perfect to me. (Michigan, USA)

Sounds right to me. I'd be more likely to say "slid", but "slipped" is perfectly acceptable in my opinion.

I believe the correct way would be “The car slipped off *of* the road" You will definitely be understood if you say that though; my dialect removes a bunch of "of"s, including the one in the sentence above PLEASE NOTE: The “of” wouldn't be said, but it will potentially be written depending on the dialect. What I mean is that you write "The car slipped off of the road", but you would say "The car slipped off the road". You only say “off” since “off of” is kinda clunky and somewhat difficult to say
