What action should a driver take when approaching a blind turn?

When approaching a blind turn, it is essential to slow down and be prepared to stop. This action is crucial because blind turns obstruct the driver's view of what lies ahead, making it difficult to see oncoming traffic, pedestrians, or obstacles. By reducing speed, the driver can improve their reaction time and gain better control of the vehicle, which increases the safety of everyone on the road.

Additionally, being prepared to stop allows a driver to react appropriately to unforeseen circumstances that may arise, such as another vehicle or person unexpectedly coming into view. This practice reduces the likelihood of accidents and contributes to safer driving overall, especially in situations where visibility is compromised.

The other options suggest actions that could increase risks. For example, accelerating cautiously might lead to loss of control if something dangerous appears suddenly. Ignoring traffic signs is unsafe as those signs provide critical information that aids in safe navigation. Signaling other drivers is indeed helpful for communication, but it doesn't address the primary need for caution and readiness when the visibility of the turn is limited.
