What factors does Minnesota law require for determining the reasonable speed limit under existing conditions?

  1. Time of day, weather, and traffic

  2. Weather, traffic, and road conditions

  3. Road conditions and posted speed limits

  4. Weather, driver age, and road conditions

The correct answer is: Weather, traffic, and road conditions

The correct answer encompasses weather, traffic, and road conditions as key factors that Minnesota law necessitates for setting a reasonable speed limit under existing conditions. Each of these elements plays a critical role in understanding what constitutes a safe driving speed. Weather can significantly impact visibility, road traction, and overall driving conditions. For instance, rain, snow, or fog may require drivers to reduce their speed to maintain safety. Traffic is another essential factor, as higher volumes of vehicles can lead to congestion, necessitating a lower speed limit to allow for safe maneuvering and response times. Road conditions refer to the physical state of the roadway, including any potential hazards such as potholes, construction zones, or debris that may require adjustments in speed for safety. Together, these components help establish a reasonable speed limit that reflects the dynamic and variable nature of driving conditions, ensuring safety for all road users.
