With the new school year starting this week, Texas officials are reminding drivers to slow down and watch for school buses and children. State law requires drivers to stop when a bus is loading or unloading students, indicated by flashing red lights and an extended stop arm. Passing a stopped school bus can mean fines of up to $1,250 for a first offense. Drivers should also obey reduced speed limits in school zones and stay alert for crossing guards and students in crosswalks. Officials say extra caution now can prevent tragic accidents later.
