Permits are needed to operate certain types of restricted access vehicles. These permits grant access to such vehicles to certain parts of the road Network under specific operating conditions. Permits are issued for different classes of vehicle. For a full list of permit classes, please view the Agency's website.
To operate a restricted access vehicle you will also need to hold a driver's licence in the correct class, and obtain heavy vehicle accreditation. The Agency may authorise some classes of restricted access vehicles to operate without a permit.
