What should drivers do when they approach upcoming exits, according to the sign?

When approaching upcoming exits, drivers should merge into the necessary lanes in preparation for their exit. This action is critical for ensuring a smooth transition off the highway and reducing the risk of accidents. Signage indicating approaching exits serves as a warning for drivers to adjust their position on the roadway, allowing them adequate time to safely change lanes without abrupt movements.

This process also involves being aware of other vehicles on the road, as multiple drivers may be attempting to exit at the same time. By merging into the appropriate lanes well in advance of the exit, drivers can help maintain traffic flow and minimize sudden stops or lane changes that could lead to collisions.

The other choices do not align with safe driving practices in this context. Accelerating without regard for upcoming exits can lead to dangerous situations, as it may result in a driver missing the exit or needing to make a hazardous lane change at high speeds. Changing direction on a whim while approaching an exit also poses risks, as it can confuse other drivers. Finally, stopping to read further signs is impractical and unsafe when in transit, as it can disrupt traffic and create hazards on the roadway.
