A week-long traffic blitz in Port Douglas has resulted in a number of drivers being nabbed for what police describe as "life-endangering offences."

Of most concern were the four drivers who were caught failing to stop at stop signs - an act which could have disastrous consequences.

In addition, three drivers were issued with speeding infringements and one for not wearing a seatbelt.
