Hamilton drivers who flout road rules at intersections face instant fines and demerit points as police move to fight the rising cost of city car crashes.
Last Thursday alone, 16 calls were made to the police 111 emergency number to report crashes in the city, and an accident priority map detailing the 40 worst intersections shows a social cost climbing into the tens of millions of dollars.
The social costs are calculated on the attendance of ambulance, police, and fire to the scene together with the cost of hospital and ACC treatment for victims.
From next month, the Hamilton police strategic traffic unit will monitor the 40 high-risk intersections in a joint effort with the Hamilton City Council to reduce the number of crashes.
Acting Sergeant Steven Jones, the unit manager, said police would target drivers who run amber or red lights and those who blocked intersections at peak times.
