Traffic delays after an accident anywhere in the state should have nothing to do with how long it takes crash investigators to arrive ("The real reason Sydney ground to a halt", March 10). The first police officers to arrive should be trained to take the necessary photographs and details of the crash that the investigators require. If need be, the investigators can visit the scene later. Minimally interrupted traffic flow, not pernickety legal concerns should be the priority. And the cost saving would be enormous.
