Because schools are now in session, the Oro Valley Police Department is advising drivers to be extra cautious when driving in populated areas and school zones.

In a news release, police reminded drivers that they may not pass a school bus when it stops and displays a stop sign with red flashing lights. Where there is no physical median, traffic in both directions must wait for the bus.

Drivers should remember that they must go slower than 15 mph when in a school zone and are not allowed to pass other vehicles within the zone. They should also be aware of crossing guards and obey their instructions. Motorists must stop when pedestrians enter crosswalks.

Police also recommend motorists refrain from texting while driving and anticipate longer travel times when driving when school is in session.
