What indicates that a driver feels that merging space is safe?

The indication that a driver feels that merging space is safe is primarily reflected in the use of a vehicle's turn signal to show intent for a turn or lane change. When a driver activates their turn signal, it communicates to surrounding vehicles that they are planning to merge or change lanes. This action helps create a predictable environment for other drivers, who can then respond appropriately.

The act of signaling demonstrates the driver’s awareness of their surroundings and intention to safely enter the adjacent lane. It is a fundamental part of defensive driving, allowing for a smoother transition and reducing the chances of collisions. When other road users see a turn signal activated, they can adjust their speed or position accordingly to accommodate the merging vehicle.

The other options indicate different forms of behavior but do not directly point to the driver’s feeling of safety in merging. A change in speed may reflect an adjustment as they approach a merge but does not, on its own, signify that the driver believes it is safe to proceed. Maintaining eye contact can indicate awareness of other vehicles, but it does not convey intent. Hand signals, while they can communicate information, are less commonly used today compared to electronic signals and might be misinterpreted or overlooked. Therefore, the clear and standard practice of using turn signals
