Actress Amanda Bynes was recently caught smoking an unknown substance while behind the wheel.
Several patrol officers are allegedly now on alert because they fear her driving habits could be deadly.
Law officers - who don't want to be named - reportedly spoke out after her two alleged hit-and-run accidents and website TMZ.com published photos of her committing the most recent act.
One said: ''She's on the same road as my wife and kids and I'm scared about getting a call in the middle of the night that my little one is dead.
''She's addicted to something and she's driving a deadly weapon and is going to kill someone. It scares the s**t out of me.''
Amanda was apparently driving around on Tuesday (11.09.12) while puffing out of what appeared to be a marijuana pipe in Los Angeles on a suspended license.
Another said: ''The public should be afraid of her. From looking at the photos, and what she's smoking, she has no sense of reality. If she's not stopped she's gonna kill someone.''
She then went to a spa, where she spent three hours before going on to violate various Traffic laws.
Another member of the police force said: ''She is going down a road that she cannot come back from when she injures or kills someone. The photos don't surprise me at all.''
The Department of Motor Vehicles suspended her license on August 25 after she is believed to have refused to take a sobriety test when she was stopped for Driving Under Influence in April.
