Austin FX4/FL2 : PCO Conditions of fitness
Since 1850, the Public Carriage Office’s Conditions of Fitness have set the standards to which all purpose-built taxicabs licensed for use in London must conform.
Naturally, they have been adapted and updated over the years to reflect the move from horse-drawn Hackney carriages to the first motor cabs, and remain subject to revision in order to reflect the changing demands of taxi trade. On this page you can read the conditions which were in force in September 1971, just as the FX4 was about to find that it had the market to itself.
Every cab must comply in all respects with the requirements of any Acts and Regulations relating to motor vehicles in force at the time of licensing.
The steering wheel must be on the offside of the vehicle.
The steering mechanism must be so constructed or arranged that NO overlock is possible and that the road wheels do not in any circumstances foul any part of the vehicle.
The steering arms and connections must be of adequate strength and as far as possible protected from damage by collision.
Brake and steering connections
Where brake and steering connections are secured with bolts or pins, the bolts or pins must be threaded and fitted with approved locking devices and they must be so placed that, when in any position other than horizontal, the head of the bolt or pin is uppermost.
The vehicle must be capable of being turned on either lock so as to proceed in the opposite direction without reversing between two vertical parallel planes not more than 28ft apart.
The wheel turning circle kerb to kerb on either lock must not be more than 25ft in diameter.
All tyres at normal pressure under load must be approved as having a suitable minimum circumference for correct operation of the taximeter.
All brakes must act directly on the wheels of the vehicle.
The brakes of one of the braking systems must be applied by pedal and, with the exception of the stop-light switch, no brake mechanism may operate any other separate mechanism.
The pedal-operated braking system must be so designed that notwithstanding the failure of the brakes on the front or rear pair of wheels there must still be available for application, brakes on the other pair sufficient to bring the vehicle to rest within a reasonable distance.
Cable connections are not permitted in the pedal-operated system and only if specially approved in the handbrake system.
Every vehicle must be fitted with an efficient suspension system so designed and constructed that there is no excessive roll or pitch.
Every vehicle must be so constructed or adapted that a failure of a spring, torsion bar or other similar component of the suspension system is not likely to cause the driver to lose directional control of the vehicle.
When the vehicle is complete and fully equipped for service and loaded with weights placed in the correct relative positions to represent the driver and a full complement of passengers and luggage and is placed on a plane surface, it must not overturn when the plane is tilted to either side to an angle of 40° from the horizontal.
If a roof rack is subsequently fitted the vehicle must be re-submitted for this test.
For the purposes of this Condition 140lb shall be deemed to represent the weight of one person and 140lb the weight of a full complement of luggage.
For the purposes of conducting tests of stability the height of any stop used to prevent a wheel from slipping sideways must not be greater than two-thirds of the distance between the surface upon which the vehicle stands before it is tilted and that part of the rim of that wheel which is then nearest to such surface when the vehicle is loaded.
If the vehicle is submitted with a roof rack half the luggage is to be on the roof.
