I want to re-join the road. What is the correct assessment of this situation?

Your answer is correct because both points 1 and 2 accurately describe the dangers when re-joining the road from a parking spot or sidewalk:

1. Drivers only see you late – Vehicles traveling on the road have less time to notice and react to your movement when you suddenly enter the traffic flow. This reduces safety if you don't pay close attention.

2. You only see vehicles late – Since your visibility of oncoming traffic is limited (e.g., by parked cars or buildings), you also have less time to judge gaps and speed of vehicles before merging.

The third option is incorrect because, as a vehicle re-joining the road, you do not have priority. You must yield to traffic already on the road and wait for a safe gap before merging.

In summary, always be especially cautious when re-joining the road. You and other drivers are both at a disadvantage in terms of visibility and reaction time, so yielding and careful observation is essential to avoid accidents.
