First off… These comments pertain to the issues in the Province of Ontario (VA3/VE3) but you could use the same arguments in your location if needed…
There is currently a debate going on about the lack of exemption to/for Amateur Radio Operators in VA3/VE3Land under the new Driving while distracted laws in Ontario.

As an Amateur in Ontario I freely give my time and the use of my equipment to support various public service events and ARES Activities in my immediate neighborhood and the localities surrounding them. This includes mobile Amateur Equipment with a replacement value of over $1200.00 (FT857 +FT2900 and antennas) plus taxes. This equipment is sitting in a kit ready to be installed in whatever vehicle I would be using because I no longer own a vehicle. 
Currently Amateur Radio Operators have an exemption (time limited) so we can come up with solutions (blue tooth) to comply with the hands free demands of the new law.
The question I find myself asking is why should I ??? Why should I tie up valuable resources on the chance I might need them??? Having a mobile radio (or two) was a worth while thought when I might put them in a Rental a couple of times a year for family trips and if I needed to I could put them in vehicle for a public service event as well. It sorta justified having them around just in case…
Just about the rest of Canada’s Provinces and territories seem to have less restrictive laws on this topic and the strange part they seem to have needed emergency communication support in the last little while. ARES was active with the Manitoba Floods, ARES was active the the Alberta Fires recently in Slave Lake, ARES and Amateur Radio play a big part in the Province of BC and the emergency plan. Currently Quebec is having Flood Issues as well and RAQI is there assisting… These provinces and others undersand the need for backup communications support. A big part of that support is happening because we as amateurs can use the equipment we already own in our vehicles. Now perhaps if we had a “good disaster” here in Ontario then the goverment might look at us in a different light but we don’t want to put that theory to the test… Or at least I don’t!!!
Its a simple fact of life… The money is becoming tighter so why would I want to tie up valuable money on equipment I can’t use unless its an emergency???

This is not about withdrawing services but more about the quality of the equipment I will be bringing if needed… I guess the repeaters will be up and running so my handheld and the rubber duck should be fine and as the repeaters are up we won’t need HF for backup to the VHF net. I’ll still be there if needed (or if asked) but the 100w mobile HF Rig and the 75w VHF Mobile Rig along with the suitable antennas might not be… This is a lot of money (for me at least) to have sitting in the box just so I can use it in an emergency…

The Amateurs who do public service all seem to think that we can still use our radios parked at the checkpoints (very true with the key word parked there) and so they are not directly affected… But many of the bodies who assist with these events might not want to help out as they no longer have a need for mobile radios… Why have it if you can’t use it???
In my opinion this very shortsighted law will hamper public service and backup communications in the long run. The cost of providing communications gear in case its needed is too great. If I can’t use it then why keep it.
I stress that I am not talking about withdrawing services…
Just that once this temporary exemption for us runs out the quality of the tools I bring when asked to serve my community will be not as high as it once was…
