Two Park Middle School students were hit by a car Friday morning while crossing the street on their way to school, police said.

The students, age 12 and 14, did not suffer any serious injuries, Kennewick police Sgt. Ken Lattin told the Herald.

The boys were on their way to school early and were two-thirds the way across 10th Avenue when Marcos Maura-Bergues, 35, of Kennewick, hit them while they were in the crosswalk, Lattin said.

There was no adult crossing guard on duty yet, but the yellow school zone lights were flashing, he said.

The lights activate at 7:05 a.m., and the accident happened about 7:10 a.m.

Police were called about 10 minutes later after the students and the driver walked into the school and told the principal what happened, Lattin said.

Maura-Bergues failed to clear the frost off his windshield and apparently couldn't see clearly as he drove, Lattin said.

He was cited for second-degree negligent driving. He was driving a 2000 Dodge Intrepid.

The students were treated by Kennewick Fire Department paramedics for minor bumps and bruises and released to their parents.
