Lane discipline ensures orderly and safe movement. Staying in the correct lane minimizes unpredictable driving and sudden lane changes, leading to a smoother and more efficient traffic system.

Use the left lane unless overtaking. Return to it after passing to avoid blocking faster-moving traffic.

The right lane should only be used for overtaking. Lingering in the lane unnecessarily causes traffic build-up and can frustrate others.

Use mirrors, signal early, and check your blind spots. Never weave between lanes or cut off other vehicles.

Use the left lane for left or straight, and right lane for turning right. Always follow road markings and signs.

Arrows show mandatory directions or intended movement. Following them prevents conflicts and confusion.

These lines enforce lane separation. Only cross them in emergencies or when directed by Gardaí or road authorities.

These allow flexibility but not careless movement. Always check surroundings before switching lanes.

Changing lanes rarely saves time. It increases collision risk and disrupts traffic flow. Stay in your lane and be patient.

Use the acceleration lane to blend smoothly. Never force your way in-let gaps form and signal your intent.

Do not enter these lanes unless signs permit it. Some operate part-time, so check the hours posted.

Never block an intersection. Enter only if you can exit fully without stopping inside the box.

Work zones may alter usual lane use. Stay alert, slow down, and follow detour instructions carefully.

Know where you are going and position early. Lane confusion causes sudden swerves and accidents.

Staying in the correct lane prevents weaving, rear-end crashes, and road rage. It also supports smoother journeys.

Always use your indicator to show intent. It alerts others and reduces the risk of a collision or misunderstanding.

Cyclists have equal lane rights. Maintain a safe distance and avoid cutting in front of them after passing.

Like motorways, the right lane is only for passing. Remaining in the left helps faster vehicles use the right.

Signs and road markings will guide you. Changing lanes last minute creates risk for side collisions.

It forces others to undertake or tailgate. Move over once you have completed overtaking to restore flow.

Always observe signage, especially in city centres and junctions. Misuse of lanes is a common test failure point.

Use all available lanes until the merge point, then take turns. This method is safer and more efficient.

Only enter a cycle lane to turn or park if signs allow. Never drive or wait in them unnecessarily.

Do not cut across lanes at the last minute. Signal early and move gradually into the left-hand exit lane.

It ensures proper clearance from kerbs, cyclists, and other vehicles. It is essential on narrow roads or high-speed routes.
