Solano County officials say Walker was driving recklessly at a high speed. They also say they have evidence that Walker was distracted by his phone at the time of the collision.
"The message needs to be sent, your actions have consequences when you make a call or answer a text, lives are at stake," said CHP Captain Mark Headrick.
Walker could face nearly eight years in prison if convicted.
