Public Safety Minister Bruce Northrup said Tuesday the changes will toughen earlier amendments, which prohibited the use of hand-operated electronic devices while operating a motor vehicle.
The new amendments make it illegal for a driver to use such devices while operating a motor vehicle even when stopped in traffic or at a red light.
But, motorists who pull off the road and stop can use a hand-operated electronic device.
The amendments will also exempt two-way radio operators from the prohibition.
Northrup says the initial amendments in 2010 allowed ham radio operators to use a two-way radio while driving during search and rescue or emergency operations, but they will now be permitted to use them any time they're driving.
