Mastering Roundabouts

Understand lane discipline, observation, and signaling for all types of roundabouts. From mini roundabouts to complex double mini systems, navigate with confidence.

Start Lesson
The Core Routine

MSPSL for Roundabouts

Apply the Mirror-Signal-Position-Speed-Look routine on approach to every roundabout.

M

Mirrors

Check mirrors well before the roundabout to assess traffic behind.

S

Signal

Signal left for 1st exit, right for 3rd/subsequent exits. No signal for straight ahead.

P

Position

Select the correct lane early. Follow signs or road markings.

S

Speed

Reduce speed to give way. Usually 2nd gear on approach.

L

Look

Look right early. Give way to traffic from the right.

Exiting Procedure

Communicating your intentions when leaving a roundabout is vital for safety and smooth traffic flow.

When to Signal

Only apply your left signal after you have passed the exit immediately before the one you want to take. Signaling too early can confuse drivers waiting to enter the roundabout, causing potential collisions.

Mini Roundabouts: Always signal left or right on approach, but be aware you may not have time to signal off at the exit due to the small size.

The Exit Routine

  • Mirrors: Check center and left mirrors for cyclists or motorbikes on your nearside.
  • Signal: Indicate left clearly and effectively.
  • Manoeuvre: Guide the vehicle smoothly into the exit lane.

Lane Discipline & Procedures

Approach with caution. Always give way to traffic from your right. Do not enter unless your path is clear.

Turning Left (Usually 1st Exit)

Signal left on approach. Approach in the left-hand lane. Keep to the left on the roundabout and exit.

Going Straight (Usually 2nd Exit)

No signal on approach. Select the left lane (unless marked otherwise). Signal left after you have passed the exit before the one you want.

Turning Right (Usually 3rd Exit)

Signal right on approach. Approach in the right-hand lane. Keep right on the roundabout until you need to exit, then signal left and move to the left lane to exit.

Visual Cues

Signs on Approach

Identifying the signage early gives you time to plan your speed and lane position.

Roundabout Ahead

A red triangle warns you of a roundabout ahead. Check your mirrors and begin to reduce speed.

Direction Map

Shows the layout of the roundabout and which exit leads to your destination. Use this to select your lane.

Lane Markings

Look for arrows painted on the road or lane signs. These define exactly which lane you must be in for your exit.

Mini Roundabout

A blue circle with white arrows indicates a mini roundabout. You must give way to traffic from the right.

Types of Roundabouts

Advanced Feature

Double Mini Roundabouts

A complex system where two mini roundabouts are joined. Treat each roundabout individually but plan your path through both.

  • Give way at the first, then assess the second immediately
  • Do not block the junction between them
  • Signal for each individual roundabout as required

Mini Roundabout

Mini Roundabouts

Identified by a painted solid white circle. You must drive around the circle, not over it, unless your vehicle is too large to avoid it. The give-way rules are the same as standard roundabouts.

Signal clearly as space is limited and events happen faster.

Spiral Roundabout

Spiral Roundabouts

Spiral roundabouts use lane markings to guide you from your entry lane directly to your exit without needing to change lanes while on the roundabout. Follow the road markings carefully.

Trust the spiral markings; they will naturally push you to the outside for your exit.

Traffic Light Roundabout

Traffic Light Controlled

Some larger roundabouts are controlled by traffic lights. In this case, standard give-way rules are replaced by the lights. If the lights are not working, revert to giving way to the right.

Be prepared for lights at the entrance and potentially on the roundabout itself.

Mastered Roundabouts?

Now that you can safely use roundabouts approach and exit, it's time to apply these skills to more complex spiral roundabouts.
