Hi Angela, This has been discussed a few times on here in the past, but it's not easy to search for them as the search facility on here won't search for 2 letter words like cb
But below are a couple of threads i did find about cb radios.

We have a 27 MhZ cb in our car when we are away with the caravan. We use channel 24 when travelling with others, and channel 11 to talk to truckies. And have it set on channel 24, and scanning channel 11, so will hear anyone on either channel. I am sure truck drivers appreciate hearing from us slower drivers so we can tell them that yes we know they are behind us and will pull to let them past when we can. On a road we are not familiar with they can often let us know when a place to pull over is coming up.
If your one had a very limited range, it was probably due to a problem with either the aerial or the coax lead from the aerial to the cb radio.
Having not used a UHF cb on our travels, I'm not sure how many others on the road use them. It seems that truckies have the other ones in their trucks, and so do lots of motorhomers. But I have heard people say that they never hear anyone on their cb, so they leave it turned off!
Hope this helps, Angela.
