MSPSL stands for Mirror, Signal, Position, Speed, Look. Drivers in the UK and many countries follow this routine to drive safely though junctions, roundabouts, crossroads, and turns.
Think of this MSPSL guide as your driving checklist. This framework ensures you make safe, informed decisions every time you approach a hazard or change direction.
The goal is to make these actions automatic. Just like you do not think about each step when you walk, MSPSL should become second nature behind the wheel.
Here are the reasons why should you follow MSPSL routine:

Each component of the MSPSL routine has a specific purpose. Here is how to apply them correctly.
What to do: Check your interior mirror first before you make any maneuver. Then check the appropriate door mirror based on your intended direction.
Common mistake: Many learner drivers glance at mirrors without registering what they see. Do not just look. Take notice. Ask yourself: Is there a car close behind me? Is a cyclist approaching? Is someone about to overtake?
Memory tip: The 7-3-21 technique helps you remember MSPSL. Think: 7 keys to safe driving, 3 seconds following distance, 21 days to form a habit.
What to do: Use your indicator to tell other road users where you are going. Timing matters. Signal too early and you confuse people. Signal too late and they do not have time to react.
The 3 house rule: Signal approximately three houses before your turn. This is roughly 100 feet. This gives others enough notice without causing confusion about which turn you are taking.
When not to signal: Do not signal if it would mislead other drivers. For example, if there is a side road very close before your intended turn, wait until you pass the first junction. This is safer.
What to do: Position your car based on your intended direction. Your position serves as a secondary signal to other drivers.
Why positioning matters: Experienced drivers can predict your intentions based on where you position your vehicle. Proper positioning also gives you better sightlines and turning angles.
What to do: Reduce your speed to approximately walking pace as you approach the junction. This is typically 10 to 15 KPH. Shift into second gear to maintain smooth control.
Practice guideline: UK learner drivers should complete around 30 hours of professional driving lessons. Learning speed control can take some time and practise.
Why slow down: Reducing speed gives you more time to observe, react, and make safe decisions. Your vehicle becomes easier to control during the turn. Your stopping distance also reduces if something unexpected happens.
Common mistake: New drivers often approach junctions too quickly. This is one of the hardest habits to break. Practice smooth, gradual braking instead of sudden stops.
What to do: Perform a final comprehensive check before you commit to your maneuver. Look left, look right, check blind spots, and scan for pedestrians, cyclists, and other vehicles.
The 12 second rule: Good drivers scan 12 seconds ahead of their current position. This means looking far down the road to anticipate hazards early. Do not just focus on what is immediately in front of you.
Hand position checkpoint: Place your hands at the 10 and 2 position on the steering wheel as you approach junctions. You can also use the 9 and 3 position. This gives you maximum control for turning.
You will use MSPSL constantly while driving. It applies to many different situations. Here are the most common ones:
You need to use full MSPSL at every T-junction, crossroad, or intersection. Follow all five steps whether you turn left, right, or go straight. This ensures you stay aware of traffic from all directions.
Roundabouts can be intimidating. MSPSL makes them manageable. Apply the routine as you approach. Make sure you are in the correct lane, traveling at an appropriate speed, and checking for vehicles already on the roundabout.
Four-way intersections demand extra attention. Use MSPSL to prepare well in advance. Make sure you look in all directions before you proceed.
Apply MSPSL any time you change direction. Even simple residential turns benefit from the routine. You never know when a cyclist or pedestrian might appear.
| Stage | Physical Action | The ‘So What?’ (Primary Benefit) |
|---|---|---|
| Mirror | Check interior, then door mirror. | You spot hazards and make a safe judgement |
| Signal | Indicate 3 houses before the turn. | You show others what you’re about to do, so they can guess your next move and drive safer around you. |
| Position | Move left or just left of center. | You use it as a clear signal, and it also protects the space around your car. |
| Speed | Brake to 10–15 KPH; shift to 2nd gear. | You keep control of the car and give yourself extra time to react. |
| Look | Scan left, right, and ahead. | A final decision point to confirm “Can I go?” |
Even experienced drivers sometimes make these errors. Watch out for these pitfalls:
You create danger when you fail to check mirrors or check them too quickly without processing the information. Always take a full second to observe what is around you.
Some drivers get lazy about signaling. They skip it when they think no one is around. Always signal. You never know when a pedestrian or cyclist might be approaching.
You create unpredictability when you approach junctions at wildly different speeds. Aim for smooth, consistent deceleration every time.
Going through the motions of MSPSL without truly paying attention defeats the purpose. Stay engaged and focused on your surroundings at all times.
