Judging Speed and Gaps at Junctions

When approaching a junction or emerging into traffic, it is essential to accurately assess the speed and distance of approaching vehicles. One of the most common errors is not a failure to look, but a failure to judge correctly. Learners often see a vehicle, but miscalculate its speed, selecting an unsafe gap to move into the main road.

This can cause other road users to brake sharply or change direction, which would result in a driving test fault and, more importantly, creates unnecessary risk.

Effective observation is not just about turning your head. It is about:

Assessing how fast vehicles are travelling

Judging whether the gap is genuinely safe

Rechecking immediately before moving

A useful strategy is to think like a pedestrian. Ask yourself:
“Would I feel safe walking across this road right now?”

If the answer is no, the gap is not suitable for driving into either.

Open and Closed Junctions

There are two main types of junction:

Open Junctions

These provide a clear and unobstructed view of the main road.
You can see approaching traffic early and assess speed and distance sooner.

Closed Junctions

These have restricted visibility due to buildings, parked vehicles, hedges or bends.
In these situations, you must adjust your technique.

At closed junctions, use the Creep and Peep method:

Stop at the give way line.

Lean forward to improve your view past obstructions.

Creep forward slowly under full control.

Continue observing both directions before committing.

You must be able to see the whole road is clear before emerging. Guessing is not a strategy.

Vehicle Control When Moving Off

Automatic Vehicles

Automatic cars simplify the moving-off process. Acceleration is immediate when the accelerator is pressed, and many modern vehicles, such as the MG4, automatically release the electronic handbrake when power is applied. This allows for a smooth and efficient entry into traffic once a safe gap is identified.

Manual Vehicles

Manual drivers should apply the POM routine (Prepare, Observe, Move):

Prepare: Select first gear and find the biting point.

Observe: Check both directions again and blind spot if required.

Move: Release the handbrake and move off smoothly without hesitation.

Being fully prepared before the gap appears prevents delay and reduces the risk of stalling or rushing.
