What is the bus driver's responsibility regarding standees (passengers standing in the aisle)?

STANDEE RULES in bus operations vary by service type and are a licensing exam topic because violations create serious safety hazards in emergencies and crashes. INTERCITY AND CHARTER BUSES (highway operation): Standing passengers are generally PROHIBITED — federal regulations (49 CFR 392.62) prohibit standees on buses operating in intercity service at highway speeds; all passengers must be seated and seated passengers must be strapped with seatbelts if the bus is equipped with them; TRANSIT AND LOCAL BUSES (urban operation): Standees are permitted within the legal capacity and regulations for that service; most transit buses have a STANDEE LINE (usually painted or marked near the front) behind which standing passengers must remain — this keeps the front of the bus (and the area around the driver) clear; CAPACITY LIMITS: The bus certificate or permit specifies the total capacity including standing room; the driver must not exceed this; SAFETY RATIONALE: In a crash or emergency stop, standing passengers are thrown forward and can be seriously injured or can injure seated passengers; intercity highway operations at 55-70 mph make standing extremely dangerous; transit operations at lower urban speeds with more gradual stops are safer for standees.
