What is recommended when driving through tunnels and bridges?

When driving through tunnels and bridges, being prepared for limited space is essential. These structures often have narrower lanes and lower ceilings compared to regular roadways, which can reduce your maneuverability. This environment requires heightened awareness of your vehicle's dimensions and the need for maintaining a safe distance from surrounding vehicles. Additionally, the confined space can affect air circulation and visibility, so being mentally prepared helps in responding effectively to any emergencies or changes in traffic conditions.

The other options, such as increasing your speed, staying close to other vehicles, or keeping your headlights off, do not promote safe driving practices and could lead to an increased risk of accidents, especially in these more restricted environments.
