What can impair your attention when driving through a tunnel?

When driving through a tunnel, certain factors can significantly impair your attention, specifically the reflections of light from oncoming traffic and the length of the tunnel.

Reflections of light can create glare that distracts drivers, making it harder to see the road and react to potential dangers. This is particularly pronounced in tunnels where light levels vary dramatically between the entrance and the inside.

The length of the tunnel can also affect attention because it can create a feeling of disorientation or fatigue. Long tunnels may contribute to a monotonous driving experience, leading to reduced alertness.

While good road markings are essential for safe driving, they do not impair attention; rather, they help guide drivers. Therefore, focusing on the distractions from oncoming traffic and the tunnel's length is crucial for safe driving in such environments, as emphasized in German traffic regulations. This highlights the importance of being aware of your surroundings and potential distractions to maintain safety.
