The vast majority of buses in the London fleet do not have offside sun blinds - particularly double deck vehicles like New Routemasters. Transport for London (TfL) regularly meets with its bus operators and with bus driver unions, and is not aware of this having been raised as a particular concern. If such concerns arise, they should be raised in the first instance by bus driver representatives with their respective operating companies. If this has already happened and not been satisfactorily addressed, bus driver representatives can raise the issue with TfL via the formal engagement channels. TfL can then take up the issue as part of its regular engineering discussions with its bus operators.
