Holding a phone while driving is now illegal in Denton.
The City of Denton passed the ordinance banning all phone use while driving effective Thursday.
Denton Police Department spokesman Bryan Cose said an officer just needs to see a device in use to stop a driver and issue a ticket.
"If the phone is up and someone is talking on it, that's all the evidence the office needs," he said. "The only time an officer will physically take someone's phone or seize it is with a proper search warrant."
Using a phone while driving is a Class C misdemeanor and carries a fine of up to $500.
Drivers can look at phones only while stopped. Drivers can use phones for calls or as a GPS unit if the phone is mounted.
