What should a perceptive driver do when unsure about having enough time or space to pass safely?

When a perceptive driver is unsure about having enough time or space to pass safely, deciding not to attempt the pass is the most prudent course of action. This cautious decision prioritizes safety over urgency. Making the choice not to pass allows the driver to assess the situation further, recognizing that hesitation is often a sign that conditions may not be ideal for passing.

By choosing not to overestimate their ability to navigate the situation safely, the driver avoids potential risks, such as colliding with oncoming traffic or not having adequate space to merge back into their lane. This approach reflects good judgment and discipline on the road, fostering safer driving habits that benefit not just the individual driver but also other road users.

Other options, like attempting to pass quickly or passing anyway, could lead to dangerous situations, while proceeding with caution may not address the uncertainty effectively. Thus, opting against the attempt aligns with safe driving practices.
