What is the tourist season in Europe, during which drivers should exercise extra caution?

Answer: C — May through September

The tourist season in Europe is typically considered to be from May through September, during which the number of tourists significantly increases due to favorable weather and school holidays. This period often sees a surge in vehicles on the roads, as tourists travel to various attractions, cities, and natural sites. Drivers should exercise extra caution during these months because of several factors, including increased pedestrian traffic, unfamiliarity of tourists with local driving laws, and potential congestion in high-traffic areas. The presence of recreational vehicles and the likelihood of distracted driving—common among tourists navigating unfamiliar places—further contribute to the need for heightened awareness on the roads. While other options reflect various months of the year, they do not align with the time frame when tourism peaks in most European destinations, which is primarily concentrated in the warmer months of late spring and summer.
