Big trucks speeding by and small students make for a potentially fatal combination in front of a Hunts Point school, complain parents.

Parents with children who attend the Bronx Charter School for the Arts began a three-day protest Wednesday, chanting that they want a crossing guard. They're also demanding a traffic light at Longwood and Garrison avenues.

They say many adults don't even clear the bottom of windshields on the large trucks, so how can a child. Parents also say truck drivers fail to obey school crossing signs and other rules.

"Navigating this street, there are kids," says parent Jackie Carroll. "Trucks that pass even if the buses are stopping and have their stop sign out. It's not safe."

The Department of Transportation has determined in the past that the area traffic doesn't warrant a traffic light.
