VHF LADD (Logging Administration Dispatch), LD (Loading Channels) RR (Road Resource) channels, standardized for trucking, delivery and use in remote areas for truck-to-truck, truck-to-base and emergency services communications with trucks, loading channels, etc. These frequencies are known by several names, including the Ice Road Channels, Loading Channels, LD channels LAD channels, LADD channels, Resource Road channels, Logging common, VHF trucking channels, Canadian trucking channels and several other combinations of these. In remote areas of Canada, specific sections of roads are assigned specific channels. See this official list:

While these frequencies were originally intended only for use by logging companies, remote dispatch (think Ice Road Truckers) and other specialized use, the proliferation of inexpensive VHF-FM equipment means their usage has become more widespread. The LADD and RR frequencies are used as an adjunct to CB radio (called General Radio Service in Canada - same frequencies and modes as the USA) in some places, and in others, CB radio is used as an adjunct to the VHF LADD and VHF RR and LD channels. Note that the similar MURS VHF CB frequencies are not permitted in Canada for these purposes. Trucks should still retain regular 27 MHz AM CB radios in addition to a VHF radio with LADD/LD/RR channels programmed into memory.

Note that the 4 LADD channels are still in regular FM (20 kHz bandwidth) while the 5 LD (Loading Channels) and 35 RR (Resource Road) channels are narrowband FM (NFM or FMN - 11.25 kHz bandwidth). CTCSS (PL) or DCS (DPL) should not be used on any of these frequencies. Receivers must be set for carrier squelch or CSQ mode.
