New rules for driving tests will come into force over the next few months, said the Driver and Vehicle Standards Agency.
It wants to make the booking system fairer and end the practice of agents creaming off additional charges from learners who struggle to find slots.
From 12 May, only learner drivers will be permitted to book, change or swap a car driving test, while from 9 June, restrictions will apply when changing the location of a booked examination, the DVSA said.
This further change will only allow learners to move their test to the three nearest centres to where their test is booked.
Roads Minister Simon Lightwood said the move would reduce long waiting lists and prevent slots being sold at inflated prices.
