Commuters, put down that phone.

The NYPD has launched a 24-hour crackdown on drivers using hand-held cell phones.

The strict enforcement began at midnight.

If you’re busted with your hands on a cellphone instead of the steering wheel, you’ll be slapped with a $130 summons.

And don’t forget, it’s not just talking on a hand-held cell phone. Texting while driving is also banned.
