Comprehensive Guide to Approaching and Driving Through Crossroads in Great Britain
Crossroads (where two roads intersect) require careful observation, correct positioning, and adherence to priority rules. This guide covers British road laws, Highway Code rules, and safe driving techniques for crossroads in the UK.

1. Understanding Crossroads
A crossroads is where two roads cross each other, forming a four-way junction. Unlike T-junctions, crossroads involve traffic from four directions, making them more complex.
Types of Crossroads
Unmarked Crossroads
No signs or road markings (basic "give way" rules apply).
Marked Crossroads
Has stop lines, give way signs, or traffic lights.
Staggered Crossroads
Roads do not align directly (treated as two separate T-junctions).

2. Priority Rules at Crossroads
Priority (right of way) depends on:
- Road markings (e.g., dashed "give way" lines, stop signs).
- Traffic lights (if present).
- The "right-hand rule" (if no signs exist).
A. Unmarked Crossroads (No Signs/Lights)
- No one has automatic priority (Highway Code Rule 172).
- Slow down and be prepared to stop.
- Give way to vehicles coming from the right (if arriving at the same time).
- If turning right, give way to oncoming traffic going straight or turning left.
B. Marked Crossroads (Give Way/Stop Signs)
- Broken white lines = Give Way (slow down and stop if necessary).
- Solid white line + "STOP" sign = Must come to a complete stop.
- Traffic lights = Follow signals strictly.
C. Traffic Light Crossroads
- Green light = Proceed if the way is clear.
- Amber light = Stop unless unsafe to do so.
- Red light = Must stop behind the line.
- Advanced stop lines (bike boxes) = Do not enter unless turning and the exit is clear.

3. How to Approach a Crossroads (MSPSL Routine)
Use the Mirror-Signal-Position-Speed-Look (MSPSL) method:
1. Mirrors
- Check rear-view and side mirrors for traffic behind.
- Be aware of cyclists and motorcyclists filtering.
2. Signal
- Left turn = Indicate left in good time.
- Right turn = Indicate right early.
- Going straight = No signal needed (unless changing lanes).
3. Position
- Turning left = Stay close to the left kerb.
- Turning right = Move towards the centre line (but do not cross it).
- Going straight = Maintain normal lane position.
4. Speed
- Reduce speed smoothly when approaching.
- Be prepared to stop if other vehicles are approaching.
5. Look
- Check all directions (left, right, ahead, and behind).
- Watch for pedestrians crossing.
- Make eye contact with other drivers if unsure of priority.

4. Turning at Crossroads
A. Turning Left
- Mirrors → Check left for cyclists.
- Signal → Left indicator on early.
- Position → Stay near the left kerb.
- Give way → To pedestrians and oncoming right-turning vehicles.
- Turn → Steer smoothly into the left lane.
B. Turning Right
- Mirrors → Check right mirror and blind spot.
- Signal → Right indicator on in good time.
- Position → Move just left of the centre line.
- Give way → To oncoming traffic (unless you have a green filter arrow).
- Turn → When safe, steer into the right side of the new road.
C. Going Straight Ahead
- No need to signal.
- Maintain normal speed (unless traffic is stopping).
- Watch for vehicles turning across your path.

5. Common Hazards & Mistakes
- ❌ Assuming priority (always check even if you think it’s your turn).
- ❌ Cutting the corner when turning right (dangerous for oncoming traffic).
- ❌ Blocking the junction if traffic is queued ahead.
- ❌ Ignoring cyclists (they may be in blind spots).
---
6. Emergency Situations
- If an emergency vehicle approaches, do not enter the crossroads unless directed.
- If traffic lights fail, treat as an unmarked crossroads.
---
7. Key Highway Code Rules
- Rule 170: Give way to pedestrians crossing or waiting to cross.
- Rule 172: At unmarked junctions, no one has priority—proceed with caution.
- Rule 173: Watch for cyclists and motorcyclists.
- Rule 174: Do not block the junction.

Final Tips for Safe Crossroads Driving
- ✔ Always approach at a safe speed.
- ✔ Be extra cautious at night or in poor weather.
- ✔ Never assume other drivers will follow the rules.
- ✔ If in doubt, give way.
By following these guidelines, you’ll navigate crossroads safely and confidently while driving in Great Britain.
