To answer the original question, for Canada at least, in my neck of the wood (Qc prov) many truckers use “FM radios” as they call them.
Depending on which company they work for, many have VHF radios on company freqs but also use these VHF commercial radios on wide-area designated (simplex) frequencies for wood-logging and can thus talk between different company trucks (outside back-country wood-logging areas).
In B.-C. Province they have a similar concept, which they call LADD channels, they are simply 4 designated frequencies for wood-logging.
…But they tend to use them outside back-country roads as an alternative to (sadly) extremely short-range CB.
