Frequently Asked Questions
What qualifications must a Delaware school bus driver meet under 21 Del. C. § 2708?
Under Delaware Code Title 21 § 2708, school bus drivers must be at least 18 years old with at least one year of driving experience, hold a valid CDL with Passenger and School Bus endorsements, have no more than 5 points on their 3-year record, have no suspensions or revocations for moving violations in the past 5 years, pass state and federal criminal history checks, pass a Child Protection Registry check, pass an annual physical including TB testing, and complete DDOE training.
What are the dimensions of a school bus danger zone?
The danger zone extends 10 feet around the entire perimeter of the school bus, with the area directly in front of the front bumper extending up to 30 feet. The most dangerous area is immediately in front of the bus and around the right rear dual wheels.
How should Delaware school bus drivers operate at railroad grade crossings?
Drivers must activate hazard flashers approximately 200 feet before the crossing, stop between 15 and 50 feet from the nearest rail in the rightmost lane, silence the bus, open the service door and driver's window, check both directions, and cross only when certain no train is approaching, without shifting gears while crossing tracks.
When is an emergency school bus evacuation mandatory?
The current manual requires evacuation for fire or threat of fire, a bus stalled on or adjacent to a railroad-highway crossing, a position that may change and increase danger, imminent collision danger, or a hazardous-material spill requiring quick evacuation. Other emergencies require a timely comparison of risks inside and outside the bus.
What is the Delaware passing law for traffic approaching a stopped school bus?
Under 21 Del. C. § 4166, drivers approaching a stopped school bus displaying flashing red lights from either direction must stop on two-lane or three-lane roads. On divided highways with 4 or more lanes, drivers approaching in the opposite direction from the front are not required to stop.
Why are crossover mirrors critical on a school bus?
Crossover (crossview) convex mirrors are mounted on the front fenders of the bus and allow the driver to view the front bumper danger zone, ground area in front of the bus, and blind spots around the front wheels that are not visible through direct sight or flat mirrors.
