Thank you for your question. I am sorry to say the answer to your questions fairly clear and not the one you want! under the Civic Government (Scotland) Act 1982 a Taxi as opposed to a private hire is defined as " a hire car which is engaged, by arrangements made in a public place between the person to be conveyed in it (or a person acting on his behalf) and its driver for a journey beginning there and then". So this means that it is hire in the street direct between the taxi and the passenger( or someone arranging it for the passenger). So by definition any hire by telephone does not fall within the definition. The expression pre booked is misleading - it is really booked by arrangement other than directly in the street. I am afraid almost all mini cab operations work in this way.
By giving a Private Hire Taxi a job directly, by whatever means, suggests that in most circumstances, they would not have the time or opportunity to check the details of a route before starting a journey. Therefore contravening the definition of Private Hire with regards XXXXX XXXXX Taxi or Topographical Knowledge Test as per the Civic Government (Scotland) Act 1982?
