bus from the opposite direction on a normal road with a turn lane, or a road with two lanes in each direction, etc., a driver is not required to stop their vehicle. This is an unusual law, but arguably leads to a higher safety level for children, as they are then required to be picked up or dropped on the same side of the road as the bus exit on anything greater than a two-lane road as provided by RCW 46.61.370. Ohio has a similar exception for roads with four or more lanes. Drivers in Idaho and Kentucky are not required to stop for a school bus on any highway with four or more lanes when traveling in the opposite direction. Drivers in California do not have to stop on any highway that is divided or is multi-lane (2 or more lanes of travel in each direction) when traveling in the opposite direction. In Pennsylvania, the only vehicle that may pass a stopped school bus with the red lights flashing is an emergency vehicle with its flashing lights and siren activated, but only after the emergency vehicle has come to a complete stop and proceeds with due caution for any students embarking or disembarking. Enforcement In New York State, an official estimate is that 50,000 vehicles pass stopped school buses illegally every day. However, as New York State requires traffic to stop for a school bus stopped on the opposing roadway of a divided highway, the estimate may include "New York violations" that would be legal in other states. The New York State Department of Transportation once recommended that the State Legislature exempt traffic from stopping for a school bus stopped on the opposing roadway of a divided highway, but this has not been done. On a national basis, school bus drivers in the United States have reported a decrease in passing violators in recent years with improved warning devices. Despite an increase in traffic and school bus ridership, annual fatalities and injuries to children struck by other vehicles has decreased as well. However, it is unclear whether having reported a decrease in passing violators is due to difficulty to report or better compliance by motorists. When and where enforcement against violators becomes too hard, some residential streets may prohibit entry of vehicles other than school buses at certain times to effectively eliminate passing stopped school buses illegally.
