Bus & Truck Module Theory Tests

Please Note; only drivers who have passed a Full Category C (Truck) Theory Test or full Category D (Bus) Theory Test on or after September 30th, 2014, are eligible to sit a Bus or Truck Module Theory Test.

These tests can be taken in addition to either the full Bus Theory Test or full Truck Theory Test. For example; when a candidate sits and passes the Bus Driver Theory Test this provides them with a Driver Theory Test Certificate in driving a bus, plus the first part of the Certificate of Professional Competence (CPC). If within two years of passing the full Bus Driver Theory Test the candidate decides they would like to be able to drive a truck also, they can sit the Truck Module Theory Test, meaning that they do not need to sit the full Truck Driver Theory Test.

However, if the candidate decides they would also like to be able to drive a truck two years after they initially sat the full Bus Theory Test, this exemption will expire and they will be required to sit the full Truck Theory Test as normal.
