A new £1.5m driving and motorcycle testing centre includes a purpose-built enclosure to protect pipistrelle and Natterer's bats that roost on the site.
A multi-purpose test centre is designed to promote safer driving
The Driving Standards Agency (DSA) is completing a multi-purpose test centre at Hardwick Industrial Estate in Kings Lynn, Norfolk.
It is designed for the new motorcycle test being introduced on 29 September.
Car practical tests can be carried out and the centre has a manoeuvres area to test biker's control of their machines.
This part of the test will take place off-road on the centre's specially surfaced area.
Would-be riders who show a dangerous lack of skill during the off-road part of the test will not be allowed to continue to the on-road part.
Rosemary Thew, DSA chief executive, said: "The new centre is key to road safety and our overall vision of safe driving for life.
"We hope that local communities will recognise the important role of the centre in supporting road safety."
