One of your drivers started drifting over into my lane this morning when I was right beside him. I honked the horn and he went back into his lane. Then when I started to pass him, I look over and he's staring at his phone screen he's holding with one hand. Very unsafe driver who's putting lots of people at risk. Last three digits of his license plate are 313. He was driving on hwy 50 in Rancho Cordova this morning on Friday 4-3-26 before 6:30am eastbound before the Zinfandel exit.
