when do you not need to stop if a school bus is loading or unloading
School bus traffic stop laws Generally, if a stopped school bus is displaying a flashing, alternating red lamp, a driver of a vehicle meeting or overtaking the stopped bus from either direction (front or back) must stop and wait until the bus moves again or the red light is off.[1] Police officers, school crossing guards, and even school bus drivers themselves may have the power to wave traffic on, even when a red light is flashing.
Turnham Green tube station To provide a better interchange with the Richmond branch of the District line, Piccadilly line trains began stopping at Turnham Green station in the early mornings (from the first train until 06:50 Monday to Saturday, 07:45 on Sunday) and late evenings (from 22:30 until the last train) only[2][9] from 23 June 1963. During the rest of the day they run non-stop through the station as before. Local residents have been campaigning for more Piccadilly line trains to stop at Turnham Green[10] with trains only stopping in the event of delays to the District line whereby large numbers of passengers are left waiting on the platform or occasionally while scheduled maintenance work is carried out.
