The Motorcycle Action Group (MAG UK) condemns today's announcement by London Mayor Ken Livingstone that motorcycles would not be permitted to use bus lane on roads controlled by Transport for London. In a report published today, Transport for London rely on the Tanner Test to 'prove' that there would be no safety benefit to either motorcyclists or other vulnerable road users if motorcycles were allowed to use Transport for London bus lanes. This same Tanner Test was described in internal documents, leaked to MAG, as unreliable and incapable of delivering sound statistical analysis.
