While lawfully passing someone on a freeway, how much can the speed limit be raised?

Answer: B — 10 mph

When passing another vehicle on a freeway in Minnesota, the law allows a driver to exceed the posted speed limit by up to 10 mph. This provision is in place to facilitate safe and efficient passing maneuvers, ensuring that drivers can overtake slower vehicles promptly without unduly risking safety or traffic flow. It's important to remember, however, that exceeding the speed limit should only happen in designated conditions like passing and must always be done with consideration for safety and surrounding traffic. Understanding this rule helps to foster responsible driving behavior and adherence to traffic laws while promoting safer roadways for everyone.
