Merging into a short gap under time pressure
This theory-test scenario combines merging into a short gap under time pressure. The aim is to detect the developing risk early, preserve a safety margin and explain why the response is appropriate.

The situation
Stress increases tunnel vision and late decisions. The decisive clue is that the speed difference changes the available gap quickly. Do not wait for the danger to become obvious; plan for what can realistically happen during the next few seconds.
Clues to detect
- the speed difference changes the available gap quickly.
- Stress increases tunnel vision and late decisions.
- match speed early and choose one clear gap.
- Identify an escape route if the first plan becomes blocked.
Decide in the right order
| Step | Check | Safe response |
|---|---|---|
| 1 | Where can the conflict develop? | Find the sight line and conflict point. |
| 2 | How much time and space remain? | Adjust speed and distance before the situation closes. |
| 3 | What if somebody else makes a mistake? | Keep a reserve plan and communicate clearly. |
Common mistake
A common mistake is to watch one road user or rely on priority alone. That removes the escape route. In this situation you should match speed early and choose one clear gap, while showing everyone else a clear and predictable plan.
How to practise
Describe the hazard before reading the answer options. Then identify the sight obstruction or conflict line, choose speed and position, and explain the reserve plan if the situation changes.
- Pause the image before the hazard is fully developed.
- Name three clues that support the risk assessment.
- Choose a response and explain the safety margin it creates.
- Repeat with a different speed, view or position.
