For an emergency on a vision obscured road, what is the correct configuration of lamps required?

In situations involving an emergency on a vision-obscured road, the correct configuration of lamps is vital for ensuring visibility and safety for both the driver and other road users. The requirement to place lamps 100 feet behind and 100 feet in front of the vehicle is designed to provide sufficient warning to approaching traffic. This configuration allows for effective visibility from a distance, enabling oncoming vehicles to see the emergency hazard in time to react safely.

The placement of lamps not only increases visibility in both directions but also establishes a safe perimeter around the emergency situation, helping to mitigate the risk of further accidents. Having the lamps positioned at equal distances behind and in front ensures that those traveling in both directions can be adequately warned.

The other options might suggest too excessive or insufficient distances either behind or in front, which could compromise visibility or create confusion for drivers approaching an emergency scene. For instance, positioning the lamps at 50 feet behind and 150 feet in front might not present a balanced warning to drivers coming from either direction. Similarly, the larger distances proposed in some options could potentially result in delayed reactions from approaching traffic. The chosen configuration helps ensure effective communication of the emergency situation to all road users.
