Positioning, Overtaking and Motorway Procedure
Lane discipline, safe clearance, meeting and overtaking decisions, and controlled motorway joining, progress and exit.
How to study for DVSA ADI Part 1
Build instructor-level road knowledge, Great Britain legal accuracy and client-centred teaching judgement, then practise hazard timing with suitable visual material.
Core concepts
Concept 1
Road position should support visibility, stability, lawful progress and safe clearance without intimidating others.
Exam cue: Test whether the entire overtake can be completed within the visible safe space.
Concept 2
An overtake requires legality, a clear benefit, adequate view and space, and a safe return without forcing another road user to react.
Exam cue: Allow for exposed, unstable or unpredictable road users when choosing clearance.
Concept 3
Motorway joining and leaving depend on observation, speed matching, lane discipline, signs and early planning.
Exam cue: Plan lane changes from signs and traffic flow instead of making a late correction.
Risk pitfalls and guardrails
Treating the speed limit as proof that an overtake is safe.
Guardrail: Do not treat priority, a signal, a speed limit or a planned lesson as permission to ignore a changing risk.
Passing a vulnerable road user with clearance suitable only for a stationary object.
Guardrail: Do not treat priority, a signal, a speed limit or a planned lesson as permission to ignore a changing risk.
Stopping at the end of a motorway slip road as the normal way to find a gap.
Guardrail: Do not treat priority, a signal, a speed limit or a planned lesson as permission to ignore a changing risk.
Memory anchors
Safe Position
Position for view and clearance without sacrificing legality, stability or another user's safety.
Overtake Test
Check need, legality, view, speed difference, space and a safe return before committing.
Meeting Traffic
Adjust early so both road users have safe clearance at the point of meeting.
Join by Matching
Use the slip road to observe and match speed, then enter a safe gap without claiming priority.
Lane Discipline
Keep to the appropriate left lane except when signs, traffic or overtaking require otherwise.
Exit Early
Read signs, position in good time and reduce speed after entering the exit slip road.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
