Minnesota Permit Practice Test

Which statement about speed limits is true?

1. All speed limits are optional

2. Speed limits are set based on road conditions

3. Speed limits only apply during daytime

4. Speed limits can be ignored in emergencies

The correct answer is: Speed limits are set based on road conditions

Speed limits are set based on road conditions, which includes various factors such as the design of the roadway, traffic patterns, and environmental conditions. This means that speed limits are determined to ensure the safety of all road users under typical conditions, taking into account the likelihood of hazards and the nature of the road. For example, a speed limit might be lower on winding rural roads compared to straight highways to account for limited visibility and maneuverability. Other options, such as speed limits being optional or only applying during daytime, do not reflect the reality of traffic laws. Speed limits are legal requirements that all drivers must adhere to at all times unless otherwise specified. Similarly, the notion that speed limits can be ignored in emergencies undermines the fundamental purpose of speed regulations, which is to ensure safety and prevent accidents, regardless of circumstances.
