Drivers improperly using bus lanes or busways, blocking bus stops or double-parking illegally along those routes will get summonses starting at $50 and climbing to $250 for repeat violations, according to the transit agency.

With the latest expansion, the MTA said 47 routes across the five boroughs now carry active fines under the ACE program.

Last week, meanwhile, the transit agency said ACE would roll out along the Bx9 and Bx15 routes in the Bronx and the B11 and B63 routes in Brooklyn.

A 60-day warning period began Monday, during which time motorists will receive warnings instead of fines. After the 60-day period ends, summonses — also starting at $50 — will begin.

More than 1,400 buses are now equipped with ACE cameras, covering 545 miles of routes and serving more than 840,000 daily riders, according to the MTA.

The agency says routes with automated enforcement have seen bus speeds rise by an average of 5%, with some corridors experiencing gains of up to 30%.

Additionally, the MTA says routes with ACE have seen a 20% decline in collisions, a 5% to 10% estimated drop in emissions and a 40% decrease in blocked bus stops. Only 12% of drivers receive more than two violations after being fined, according to the agency.

Each route equipped with ACE includes posted signage alerting drivers that cameras are active.
