Karleen Chalker, spokeswoman for the Forsyth County Sheriff's Office, said things went smoothly on the first day of school, despite some traffic congestion at Lambert High School and a false fire alarm in the kitchen at Mashburn Elementary.

"After school had been in session for about three hours the fire alarm went off and they had to evacuate the school,"  said Chalker, who did not know how much time passed before students and staff were allowed back in the building.

Chalker said authorities will be watching school zones this week to make sure traffic laws are being followed.

"People need to be very aware when they are approaching a school zone because we do have our motor units out working, " she said.

"The first week of school is usually more congested because people are getting used to going in and out of the schools and people are bringing their kids to school for the first time."
