I was coming home from work today, [in the car] there was a woman driving a VW Golf just in front of me she had a mobile phone to her right ear but holding it with her left hand, & holding the wheel with her right hand, not only that but there was a child on the back seat of the car, as I drew alongside her I tooted the horn & told her to get off her phone. as I was in Uniform she may have thought I was a copper & quickly put down her phone, I am not into impersonating Police officers however witnessing stupid & dangerous driving like hers makes my blood boil.
