Police say an ‘‘incredibly tragic’’ morning in which four people died in three separate crashes across Victoria is further evidence that road users have been lulled into a deadly complacency.

Victoria Police Deputy Commissioner Kieran Walshe said a series of bad decisions had proven fatal and admitted police were at a loss to curb Victoria’s road toll, which now stands at 65 - 14 more than for the same time last year.
