What is the minimum distance required for parking vehicles from a warning cross indicating a railroad crossing?

Answer: B — 50 meters (165 feet)

The minimum distance required for parking vehicles from a warning cross indicating a railroad crossing is specified to be 50 meters (165 feet). This distance is crucial for ensuring safety near railroad tracks, as it allows for clear visibility of the crossing signals and approaching trains. By maintaining this distance, drivers can avoid obstructions that may hinder their line of sight to the railroad crossing, reducing the risk of accidents. This regulation is in place to protect both drivers and pedestrians, as well as to ensure that emergency vehicles have unimpeded access to the area if needed. The prohibition of parking too close to railroad crossings also helps to ensure that any warning signs or signals can be seen and adequately reacted to by vehicles approaching the crossing.
