45 MPH
Yes it is possible. There are roadways that have a minimum speed limit, such as an interstate highway.

45 mph
An Autobahn is basically a German version of a highway. ******** A VERY high speed highway- such as an expressway or an interstate highway.
The minimum will vary by locale, but will normally be either 40, 45, or rarely 50 mph for limited access highways. The minimum speed on the Interstate Highway System is either 40 or 45 mph and is set within each state based on road conditions and traffic levels.
The minimum speed on major routes (if any) varies by state. As an example, in many jurisdictions the minimum speed on a 65 MPH Interstate is 45MPH. Most states have a catch-all rule that states you can be ticketed for driving at any speed that is so slow as to impede the flow of traffic.

On any Interstate highway the minimum speed you can travel is 45 mph. On some highways that were grandfathered into the system it can be as lows as 40 mph. On state roads the minimum speed is always posted if there is one. Otherwise the law states that you cannot drive at a speed that impedes the flow of traffic. That determination will be made by an officer of the law.
