What are the tedious driving conditions described in the following picture?

1. Correct answer: Wet road, poor visibility and heavy traffic.
2. Due to the weather conditions the traffic sign is not clear.
3. A camera is installed in the intersection; therefore it is not permitted to cross when the light is red.
4. The traffic congestion in the intersection does not oblige us to be overly careful.

WhyThere are several difficulties at once here: a wet road, poor visibility and heavy traffic. Each one calls for driving slower.
