Which of the cars below can pass safely?

When considering which car can pass safely, several factors must be taken into account, including the positioning of the vehicles, road conditions, traffic regulations, and visibility.

In this scenario, Car D is determined to be the only vehicle that can pass safely, indicating that it likely has a clear path and meets all necessary conditions for passing. This could mean that Car D is in a position on the road that allows for unobstructed visibility and is moving at a speed that balances the safe execution of the pass without endangering itself or others on the roadway.

Factors such as oncoming traffic, lane markings, and distance from other vehicles play crucial roles in determining the feasibility of passing safely. If Car D is positioned in a lane designated for overtaking or if there are no visibility obstructions, it suggests an appropriate time and place to pass without risking collisions or violating traffic laws.

In contrast, the other cars—A, B, and C—likely would have impediments that prevent a safe pass, such as being directly in front of other vehicles, navigating curves or intersections, or encountering unfavorable road conditions. Recognizing when it is safe to pass extends beyond signaling and acceleration; it involves an assessment of the entire traffic scenario.
