An alleged driver driver caused emergency workers to leap for safety as she sped through a rural crash scene in Waikato.
Sergeant Neil Mansill of the Huntly Road Safety Team said he struggled to comprehend how any road user could fail to see they were approaching a crash site with the way scene was set up.
"Emergency services had been called to the crash on Tahuna Rd near Ohinewai about 4.15pm on Monday.
"There was two police cars at either end of the scene with flashing red and blue lights, a member of the public's car on the side of the road with flashing hazard lights and a tow-truck with flashing orange lights all attending a two car collision."
The driver of one of the cars had just been taken to hospital by ambulance when a car came speeding through the crash scene sending everyone leaping for safety, Mr Mansill said.
