A number of Police procedures will have to be clarified now, and they will need to be consistent across the UK. Currently, for example, the Metropolitan Police do not prosecute drivers where the evidential reading is below 40 in breath, although they do prosecute 81 in blood. If the reading is 40 to 54.9 there is an option to have a blood or urine sample. Will similar procedures be used for pilots, with the numbers pro-rata?
There are obviously no sentencing guidelines as yet, but I would be surprised if prison did not feature largely when they do emerge. As it is, bus and coach drivers are treated more severely than car drivers.
