The main purpose of providing on-ground warning at grade crossings is to prevent collisions with highway traffic. These warnings serve as crucial safety measures, alerting drivers and pedestrians to the presence of an approaching train. The goal is to enhance awareness and ensure that vehicles come to a complete stop when necessary, thereby minimizing the risk of accidents at these potentially dangerous intersections.

On-ground warnings may include devices such as flashing lights, warning signs, and gates that are activated when a train is near. By drawing attention to the train's approach, these warnings contribute significantly to overall safety for both rail and highway users.

In contrast, the other options do not accurately reflect the primary intent of these warnings. Maintaining high speed or reducing delays concerns train operations rather than safety at crossings. Allowing trains to cross without stopping relates more to operational efficiency than to the key focus on preventing collisions.
