Streets Of Speed: Donna speeders put on alert

This sign reminds drivers to slow down.

Donna speeders have been put on alert.

The Speedzapper staked out an area of South Hutto Road and found plenty of speeders rushing through the 20 mph school zone.

Buckle up and get ready for a wild ride in this week's Streets Of Speed.
