On a divided highway, what is the flag/flare distance requirement for emergencies?

In an emergency situation on a divided highway, the flag or flare distance requirement is crucial for ensuring safety and alerting other drivers to the hazard. The correct choice specifies the appropriate distances: 10 feet, 100 feet, and 200 feet to the rear of the vehicle.

Setting up the initial warning device, such as a flare or flag, at 10 feet ensures that it is visible enough to alert oncoming traffic without being too close to the actual hazard. The subsequent devices are positioned at 100 feet and 200 feet. This sequential placement provides clear visibility for drivers far enough away, giving them adequate distance to react appropriately and safely change lanes or reduce speed.

This arrangement is particularly important on highways, where vehicles typically travel at higher speeds. Properly distancing the warning signals helps prevent further accidents by allowing sufficient time for response from other drivers, who might not expect to see an obstruction or stopped vehicle ahead.
