Legally, no.
At this point as confusing as this topic is... My recommendation is for everyone to use their best interpretation and purchase what they want, from a legal perspective its not in anyones best interest to recommend a radio unless they fully understand what they are talking about. (i will not be supporting any beofungs) I say we use GMRS (UHF) , and we will define a list of PL tones that we will use on each channel. But... i want everyone to keep in mind... a "5" (probably closer to 3) watt handheld inside a vehicle isnt going to be "that great". I would still recommend everyone look into higher powered installed radios for their rigs, with antennas mounted to the body.
IMO, nobody is gonna come after you for using a non type accepted radio, nobody is gonna come after you for operating high power on GMRS and nobody is gonna come after you for using the preset rugged radio channels UNLESS ... you start causing harmful interference with other users, who are licensed. The thing I worry about most with this conversation is that someone accidentally uses a frequency that is used by a local LEO or PD or Rescue, when they hear you asking how many beers are left in the cooler, etc, they are gonna get a little upset.
