Drivers who blow past stopped school buses with the stop arms out and the lights flashing could soon face serious consequences - even if the police aren't there to witness it.

Gov. Andrew Cuomo signed the state law back in August, and on Wednesday Nassau's County Executive Laura Curran signed legislation allowing local school districts to opt in to install cameras on school buses.

Curran's office says the cameras and the software won't cost the taxpayers anything. They say the tech companies pay for the installation and in return get money collected from drivers who pay fines. 

Safety advocates say it's about time.

"So typically, if someone gets a speeding ticket, they're going to get another speeding ticket during the course of their life. They've seen a less than 2% recidivism rate so far for people who have committed this violation. That means they're not doing it again. There's just no excuse for running past a stopped school bus," says Daniel Flanzig, of Long Island Streets.

If someone is caught on camera and gets a ticket, the first offense will cost $250. A second is $275 and a third is $300.
