The NYPD says it will expand traffic enforcement to focus on violations that endanger child pedestrians beginning the week of Sept. 13.

"If you drive irresponsibly and hit someone you absolutely will not get your job done,” says one official.

One-third of fatal crashes happen in school zones at times where camera are not operating, according to the Department of Transportation.

"No family should ever have to suffer the grief and the loss of losing a child due to motor vehicle accidents,” says Assemblymember Jessica Gonzalez-Rojas.

Elected officials attended a conference on Thursday calling for the passage of legislation allowing the city’s speed camera to always operate.

With speed cameras focused on fast drivers, speeding has declined 89% on the Grand Concourse in the Bronx, 88% on Fourth Avenue in Brooklyn and over 80% on Gun Hill Road, Coney Island Avenue and Eastern Parkway.

"The more slowly drivers drive, the more time we will have to react in an emergency situation,” says TLC Commissioner Aloysee Heredia Jarmoszuk.

The Department of Transportation has already made improvements along several spots this year, including Nostrand avenue between Madison Place and Quentin Road.

Other additions include left turn lanes, painted curb extensions and crossing to make streets safer for pedestrians.
