Overtaking Rules
When overtaking is allowed, when it is not, and how to do it safely.
Why This Matters
Even if the practical test does not involve a major overtake, the tester expects strong judgement about where overtaking is forbidden or unsafe.
Coach Note
Most overtaking mistakes begin before the manoeuvre itself, with poor observation or bad location choice.
Learning Goals
- Know the safe sequence for overtaking.
- Know where overtaking is prohibited or unsafe.
- Understand the legal left-side exceptions.
- Remember that speed limits still apply while overtaking.
Sections

Where You Must Not Overtake
Road shape and conflict points matter more than impatience.
Common Mistakes
- Trying to pass because the car ahead is slow without reading the road ahead.
- Ignoring line markings.
- Starting an overtake on the run-up to a junction.
Quick Quiz
Select every place where you must not overtake.
- ✓A. Approaching a zebra crossing
- ✓B. At a hump-back bridge
- C. On a straight clear road with no restrictions
- ✓D. Approaching a junction
Crossings, bridge brows and junction approaches are specifically high-risk places where overtaking is prohibited or unsafe.
When Passing on the Left Is Allowed
Allowed only in narrow, specific situations.
Right-Turning Vehicle Ahead
You may pass on the left if the driver ahead has moved out and signalled to turn right while you intend to continue straight.
You Are Turning Left
You may pass on the left if you have signalled and are genuinely turning left.
Slow-Moving Queues
In slow-moving stop-start traffic, the left lane may move faster than the right. This is not the same as an aggressive overtake at normal speed.
Common Mistakes
- Using the left pass rule aggressively at normal road speed.
- Thinking that any open left side is legal to use.
- Ignoring pedestrian or cyclist risk while passing on the left.
Quick Quiz
When is it legally permitted to pass or overtake a vehicle on the left in Ireland?

- B. Any time you are in a hurry
- C. On hard shoulders during rush hour
- D. Whenever the driver ahead is driving below the speed limit
Passing on the left is permitted when the driver ahead has signalled to turn right, or in slow-moving lane queues.
