Minnesota Blue Card Practice Test

The correct answer is 100 feet. This distance is crucial for ensuring safety and visibility when approaching critical points like intersections, underpasses, tunnels, or railroad crossings. Maintaining a minimum distance of 100 feet allows drivers adequate time to assess the situation ahead, reduce speed if necessary, and make informed decisions about whether to proceed or stop. This distance helps to prevent accidents by ensuring that vehicles do not crowd these potentially hazardous areas, where the likelihood of conflicts with other vehicles or pedestrians increases significantly. Hence, adhering to this minimum distance improves overall road safety and contributes to a more organized traffic flow.
