DTT Give Way Rules and Junctions 2

Question 1

What is the correct procedure when merging onto a motorway from a slip road?

Accepted Answer

Accelerate to motorway speed on the slip road and merge safely into a gap

Answer

Use the slip road to match motorway speed, then check mirrors and blind spots and merge smoothly into a safe gap in the left lane. Stopping at the end of a slip road is dangerous.

Question 2

At a controlled junction (traffic lights), a pedestrian is crossing as lights turn green for you. What should you do?

Accepted Answer

Wait for the pedestrian to finish crossing before proceeding

Answer

Even when you have a green light, you must give way to pedestrians who are still crossing. A green light permits you to proceed only when it is safe — pedestrians in your path take priority.

Question 3

When should you use the Mirror-Signal-Manoeuvre (MSM) routine?

Accepted Answer

Before every turn, lane change, or change in speed

Answer

The MSM routine must be used before any manoeuvre including turns, lane changes, overtaking, pulling out, and stopping. It ensures you are aware of surrounding traffic before acting.

Question 4

What must you do when approaching a junction where the road ahead is blocked by stationary traffic?

Accepted Answer

Do not enter the junction unless you can clear it completely

Answer

You must not enter a junction if you cannot clear it and would end up blocking cross-traffic. This is the principle behind yellow box junctions.

Question 5

You approach a narrow bridge from the same direction as a sign showing a red X. What does this mean?

Accepted Answer

Traffic from your direction must give way to oncoming traffic

Answer

A red X at a single-lane bridge or narrow passage means traffic from your direction must give way. The arrow side (usually on the opposite approach) indicates which direction has priority.
