MARKED

How To Identify: Look for two roads opposite each other to identify the junction, other clues include:
Amount of traffic, Vehicles turning into / emerging from roads, Warning / direction signs, Road markings, traffic lights, Breaks in lines of houses / parked cars.

Hazard - MSPSL: 
Speed:

Major-To-Major
When going straight ahead your signal to consider is your break lights
Match speed to what you can see - Slow down until you can see it is safe to proceed

Major-To-Minor 
Treat as if turning Left or right, but with extra observation to the road opposite the one you aim to turn into  LARAL

 Note: When Turning Right

When 2 vehicles are turning right decide whether to pass:
               Nearside to Nearside / Offside to Offside
OS/OS - Safest as this gives you the best view of the road ahead, but may restrict 
                      traffic flow
NS/NS - More common as allows for a greater traffic flow, but restricts visibility

Minor-To-Everywhere 

Approach as a Left/Right emerge using the MSPSL routine. Pay attention to road markings and signs. Is the junction Open or Closed

Extra Obs:

An extra factor to be taken into consideration is the road opposite LARAL 
If there is a car opposite asess who has priority, if anyone! 
Look for clues from the driver / vehicle position / angle of wheels / signals etc.

UNMARKED

All Directions

How To Identify:

No road markings or signs (often found on country roads / housing estates).
Clues include gaps in houses/hedges/streetlights and vehicles emerging/turning.

Priorities: Never assume priority - at an unmarked crossroads nobody has priority.
