FAQ: What happens if I take my test in an automatic car ??
There is nothing different about taking the practical driving test in an automatic car, the test itself is exactly the same in terms of routes and content. When booking the test you will need to inform the DSA of your wish for an automatic test.
The major difference is that after passing, you will only be allowed to drive automatic cars with you new full licence. (As opposed to passing the test in a manual car and being able to then drive an automatic car as well)
