🚦Junctions
Junctions are where the majority of serious driving faults occur on UK tests. Whether you're emerging from a T-junction, navigating a busy crossroads, or joining a dual carriageway via a slip road, the MSPSL routine (Mirrors, Signal, Position, Speed, Look) is your foundation for every junction.
The MSPSL Routine
Every junction should be approached using MSPSL: Mirror — check your centre and side mirrors. Signal — indicate your intention in good time. Position — position your vehicle correctly for your intended direction. Speed — adjust your speed to the conditions. Look — assess the junction for hazards, other vehicles, pedestrians, and cyclists before deciding to go.
T-Junctions: Emerging Left & Right
At closed T-junctions (restricted view), inch forward slowly until you can see clearly in both directions. Use clutch control to crawl at walking pace. Never commit until you're certain the road is clear. At open T-junctions with good visibility, you can assess earlier — but still stop at the line if there's any doubt.
Crossroads: Priority & Observation
At unmarked crossroads, no one has automatic priority — proceed with extreme caution. At marked crossroads, follow the signs and road markings. If you're turning right, be aware of oncoming traffic also turning right — the "offside-to-offside" rule means you should pass behind each other unless markings indicate otherwise.
Slip Roads & Dual Carriageways
When joining a dual carriageway from a slip road, match your speed to the traffic on the main carriageway. Use the entire slip road — don't stop at the end unless absolutely necessary. Signal right, check your blind spot, and merge smoothly. When leaving, signal left at the first countdown marker (300 yards), reduce speed on the slip road — not on the main carriageway.
🚫 Common Mistakes (That Fail Tests)
- ✕Emerging when it's not safe — misjudging the speed of approaching vehicles
- ✕Not looking both ways at closed junctions (especially to the right twice)
- ✕Stopping unnecessarily at open junctions with perfect visibility
- ✕Failing to check blind spots before joining dual carriageways
- ✕Rushing the MSPSL routine — doing everything at once instead of sequentially
Instructor's Pro Tip
In East London, many junctions near test centres have restricted visibility due to parked cars. Crawl forward a few inches at a time and look right, then left, then right again — the "double right check" could save you a serious fault.
