What is a common condition in tunnels that drivers should be aware of?

While strong winds can sometimes occur in tunnels, the better answer for a common condition that drivers should be aware of is limited visibility. Tunnels often have lighting that may not be consistent, and the transition from bright daylight to dimly lit conditions can impair a driver's ability to see clearly. This can lead to difficulty in judging distances, identifying obstacles, or recognizing changes in traffic patterns.

Drivers should be particularly cautious upon entering or exiting tunnels, where the contrast in lighting can create a moment of reduced visibility that might catch them off guard. Additionally, since tunnels can often limit sight lines, other vehicles may not be visible until they are quite close, increasing the risk of collisions. Recognizing and adapting to these conditions is crucial for maintaining safety while driving in and around tunnels.
