Dual carriageways increase speed and reduce the time available for late decisions. Good planning means reading signs early, building speed appropriately and using mirrors before every lane change.
Depending on location and route, a practical test can include faster roads that test merging, lane discipline and forward planning.
Use these as practice priorities rather than a rigid scripted routine.
Use the acceleration lane to match the speed of traffic when it is safe to do so.
Check mirrors and blind spots before moving into another lane.
Keep a safe following distance and increase it in poor conditions.
Read exit signs early so you do not make a rushed lane change.
These are practical weaknesses worth fixing before test day. The exact fault grade always depends on the circumstances and severity.
Joining too slowly and forcing traffic to react.
Changing lane without an effective mirror or blind-spot check.
Remaining in an overtaking lane without reason.
Leaving route decisions until the final few seconds before an exit.
Build adaptability instead of repeating one memorised road or reference point.
