Ham radio is primarily intended for those interested in amateur radio communications as a hobby or avocation. The amateur radio community welcomes anyone with that interest, and if that is yours, then welcome! It is truly a fascinating hobby with many different aspects.
If you are interested in communication for other purposes like communication between vehicles, etc., then I agree with TucsonJim, the Family Radio Service (FRS) would probably serve you better. FRS radios are much less susceptible to noise and are more reliable for that purpose. I also agree with him, CB radio has turned into a wasteland for the most part.
Also, some of the apps available for smart phones now, such as Inrix, are very helpful for urban traffic information.
