The NYPD is testing new police vehicles with bullet-resistant glass and door panels to prevent the kinds attacks that have taken the lives of three cops recently.

“We have an obligation to protect the public,” Police Commissioner Bill Bratton said Tuesday, as he presented the first of the prototype vehicles outside NYPD Headquarters.

The NYPD plans to begin field-testing 60 vehicles.

Two of the SUVs will go to Brooklyn’s 84th Precinct, where Officers Rafael Ramos and Wenjian Liu were stationed, and Queens’ 105th, where Officer Brian Moore worked.
