Northside ISD is facing a growing problem, students being hit by vehicles.

Since school began in late August, four children have been hit in an NISD school zone.

NISD confirms that three of the four incidents where students were hit by vehicles happened in front of Ward Elementary and at neighboring Jefferson Middle School off Shaenfield near Loop 1604.

One of those incidents happened this week.

On Tuesday morning, the Bexar County Sheriff's Office said that a 10-year-old was hit by a truck leaving the parking lot of Ward Elementary. The child suffered minor injuries.

A few miles away, on Thursday morning, outside Scarborough Elementary, it was a scene that made every parent's heart skip a beat.

BCSO officials said that a van ran into a 10-year-old on a bike. The bike was left mangled under the vehicle. The child escaped with only minor injuries.

"Anytime we have even one accident, it's cause for concern," said Barry Perez, a spokesman for Northside ISD.

The district is using the accident as a teaching moment. Students are being reminded daily about the need to pay attention when going to and from school.

But there's a lesson for adults, too.

"We are stressing very, very much that we need drivers to be aware when they're going through our school zones, if they're even near a school, that they're mindful of the fact kids could be walking, kids could be on bicycles," Perez said.

By Thursday evening, Bexar County road crews added stop signs in front of Scarborough, but the district says that it still needs a permanent crossing guard.
