Minnesota Permit Practice Test

When driving on two-lane highways, the rules regarding speed limits are designed to ensure safety for all road users. The correct answer highlights that there is an allowance to exceed the posted speed limit by a certain amount—10 mph—when passing another vehicle. This exception acknowledges the need for drivers to complete overtaking maneuvers safely and efficiently without causing undue delays that might lead to dangerous situations.

This rule is essential for maintaining traffic flow and preventing extended periods of slow-moving vehicles, which can create hazards for all drivers. By allowing a temporary increase in speed during passing, it helps ensure that drivers can maneuver past slower vehicles more swiftly and return to their lanes.

The other options either imply larger or less consistent allowances, or state that there are no exceptions at all, which does not accurately reflect driving regulations concerning safe passing on two-lane roads. Understanding this specific regulation is important for safe driving and for making informed decisions in real-world situations.
