What do you have to be aware of in this situation?

You answered correctly by choosing that you have to drive with particular care and that you may be poorly visible to other road users. This situation shows a road lined with trees, creating a pattern of light and shadow.

According to German traffic rules, such conditions can reduce your visibility to others because the shadows may camouflage your vehicle in the middle of the road. Additionally, the alternating light and shadow can make it harder for you and other drivers to see clearly and judge distances accurately.

Therefore, you must be especially cautious and vigilant, driving carefully to react to any hazards in time. The choice about being more easily able to judge distances is incorrect here because the visual conditions caused by shadows actually make distance judgment more difficult, not easier.

So, always remember: when driving in conditions with strong light contrasts from road-side trees, slow down a bit, watch carefully, and assume other drivers might not see you well. This helps avoid accidents.
