Roundabouts
Purpose of Roundabouts
Roundabouts allow traffic to merge or cross paths without always needing to stop.
Priority
-
Normally, give way to traffic from your right.
-
Keep moving if the way is clear.
-
Some roundabouts have ‘Give Way’ signs on the roundabout itself, or traffic lights controlling flow.
Always use the MSM/PSL routine on approach.
Standard Procedure (Unless Signs Indicate Otherwise)
Going Left
-
Signal left on approach.
-
Stay in the left lane throughout.
-
Maintain your left signal until you exit.
Going Straight Ahead
-
No signal needed on approach.
-
Approach in the left lane (or next available lane if blocked).
-
Signal left after passing the exit before the one you need.
Turning Right or Full Circle
-
Signal right on approach.
-
Use the right-hand lane and maintain the signal.
-
Signal left after passing the exit before yours.
More than Three Lanes
-
Use the most appropriate lane for your route.
-
Follow all road markings carefully.
Defensive Driving at Roundabouts
-
Watch the vehicle in front carefully — don’t assume it will keep moving.
-
Be ready to stop if it hesitates.
-
Many rear-end collisions occur at roundabouts due to misjudged movement.
Common Hazards
-
Pedestrians: crossings may be located near entries/exits.
-
Cyclists & horse riders: may stay to the outer lane even when turning right.
-
Motorcyclists: harder to see; always double-check.
-
Large vehicles: may straddle lanes — give them space.
-
Slippery surfaces: especially in wet weather — avoid harsh braking or acceleration.
-
Other vehicles: may cross your path to exit — anticipate their movement.
Mini-Roundabouts
Approach as you would a normal roundabout:
-
Slow down and be ready to give way to the right.
-
Space and time are limited, so signalling opportunities may be shorter.
-
Give way to vehicles turning right towards you.
-
Only enter once you’re sure vehicles already on it are leaving.
-
Avoid using mini-roundabouts for U-turns, though others may do so.
-
You must drive around the central marking unless it’s physically impossible (e.g., with a long vehicle or trailer).
Double Mini-Roundabouts
-
Treat each roundabout separately.
-
Give way to the right at both.
-
Observe carefully before entering each one.
Spiral Roundabouts
-
Lanes spiral outward toward exits.
-
Follow lane markings carefully from entry to exit.
-
Stay alert for drivers changing lanes unexpectedly.
-
If you need to change lanes, check mirrors, signal, and move only when safe.
Multiple Roundabouts
At large, complex junctions, a major roundabout may include several mini-roundabouts.
-
Each mini-roundabout follows standard clockwise rules.
-
Traffic around the central island may move anti-clockwise.
-
Follow signs, lanes, and markings precisely.
-
Maintain full concentration and awareness at all times.
Remember LADA
Always:
-
Look
-
Assess
-
Decide
-
Act
Safe and consistent use of these principles ensures smooth, defensive, and responsible driving through any junction.
