Which practice helps improve visibility while towing?

Adjusting side mirrors properly is essential for improving visibility while towing. This practice ensures that the driver has a clear view of the areas adjacent to and behind the vehicle, including blind spots that are often larger when a trailer is connected. Properly positioned side mirrors significantly enhance awareness of surrounding traffic, which is critical for safe maneuvering and changing lanes.

Getting the mirror angles right allows the driver to see the trailer and other vehicles more effectively, reducing the risk of accidents. Additionally, depending on the type of trailer being towed, some drivers might use extended side mirrors specifically designed for towing, which provide an even wider field of vision.

In contrast, other options do not contribute to improved visibility while towing, such as using tinted windows, which actually can hinder visibility, particularly in low-light conditions. Driving with the headlights off reduces visibility, especially at night or in poor weather conditions, and increasing tire pressure is related to vehicle handling and safety but does not directly affect the driver's line of sight.
