Police could not confirm whether the woman had been issued the fine for using her cell phone while driving through the checkpoint but a police spokesperson reinforced the message that it is never safe to use the device behind the wheel.
"The dangers and risks associated with cell phone use while driving are well known. The safety of our community is our priority. One of our focuses is to increase awareness around risks, such as cell phone use, and getting motorists to change their driving behaviour with the aim of reducing crashes and the number of victims," the spokesperson said.
"It is against the law to use your cell phone while driving, even if your vehicle is stationary such as at a traffic stop.
"Using a cell phone while in charge of a moving vehicle approaching a checkpoint with officers standing on the road is not a particularly safe or clever thing to do. Never use your cell phone while driving – no message or call is worth the risk to your safety and the safety of other motorists."
