What should you do to maintain visibility in a tunnel?

• A. Use appropriate lighting and avoid sudden braking.
• B. Increase following distance.
• C. Drive at the maximum speed limit.
• D. Turn on high-beam headlights.

Answer: (A)

In a tunnel, visibility is challenged by lower light levels and the close, enclosed space, so you need to ensure you can see clearly and others can see you. Using appropriate lighting helps you illuminate the road ahead and makes you visible to drivers around you; in tunnels, that usually means keeping your headlights on and avoiding high beams, since bright light can bounce off tunnel walls and glare back at you and other drivers, reducing your ability to see. Avoiding sudden braking is important because abrupt changes in speed in a narrow, dim environment can surprise drivers behind you and lead to collisions, while steady speed and smooth deceleration maintain a predictable flow of traffic and preserve visibility for everyone. Other options don’t directly improve visibility in the tunnel: driving at the maximum speed limit can reduce your reaction time in this special environment, and simply increasing following distance, though safer, doesn’t address the core visibility challenge as effectively as proper lighting and controlled braking.
