These proposals would provide real deterrence, with the teeth to get irresonsibly driven cars off the road.

n the exact right soapbox at the exact right time, Mayor de Blasio is urging the state to ratchet up consequences for drivers who are crashes-waiting-to-happen on New York’s streets. After Dorothy Bruns’ car killed a 4-year-old girl and 1-year-old boy and sent their mothers to the hospital, an anguished city awakened to an infuriating fact: Her vehicle had racked up eight traffic-camera-enforced violations, for running red lights and speeding in school zones, since summer 2016.

Yet because of the way the laws work, none of them stuck to her personally or had any lasting consequences for her car.

Moreover, Bruns was behind the wheel despite being increasingly disabled by an advancing neurological disease, multiple sclerosis. In New York State, it’s optional for a doctor alarmed by the prospect of a patient operating a vehicle to report it.

It’s time for a hard turn, before any of the drivers of the 34,000 vehicles that have racked up six to 10 red-light and school-zone-speeding violations over the last 19 months (or the 6,000 that have racked up 11-20 of them, or the 600 that have racked up more than 21) leave more human wreckage in their wake.

Under legislation de Blasio champions, the days of chronic reckless driving with impunity will end. No more never-escalating $50 fines on lawbreaking caught by automated cameras; a third violation within a two-year period would hike the fine to $150.

By a fifth violation in that window, a car’s owner would pay $300 — and their insurance would be notified. (How on God’s gray pavement did this not happen before?)

Upon sixth violation, a car’s owner would get a $350 hit, and the vehicle’s registration suspended.

That’s real deterrence, with the teeth to get irresponsibly driven cars off the road.

So too would de Blasio seek to put speed cameras around 150 more schools and widen the zones.

A final bill, modeled after long-standing New Jersey law, would require physicians to notify the state DMV if they are aware of medical conditions or incidents likely to result in a driver’s sudden loss of consciousness.

Reporting is now optional, which is nonsense. According to City Hall, since 2015, seven auto fatalities have been caused by seizure-like events.

Those seven people are gone. The next seven must be saved.
