1. What is Missouri's default speed limit for a road in any city, town, or village, unless posted otherwise?
Why: Missouri's default speed table sets a city, town, or village at 25 mph unless posted otherwise -- well below the 70 mph maximum for rural interstates and freeways.
2. Does Missouri set a minimum speed on its interstate highways, and if so, what is it?
Why: Missouri interstates carry a 40 mph minimum speed under normal conditions -- if that's too fast for a driver, the guide's advice is to take a different route rather than drive below it.
3. What following-distance rule does Missouri's own Driver Guide teach as its "Three Second Rule"?
Why: Missouri's guide has you pick a fixed object near the road, then count "one-thousand one, one-thousand two, one-thousand three" as the car ahead passes it -- reaching the object before finishing the count means you're too close.
4. How far can a Missouri driver travel inside a two-way left-turn lane before it stops being legal to use as a travel lane?
Why: A Missouri two-way left-turn lane may not be used as a travel lane for more than 500 feet, and it can't be entered directly from a side street.
5. What does Missouri's guide say about making a left turn to enter a roundabout?
Why: Missouri's guide is explicit: never make a left turn to enter a roundabout -- approach with a slight right turn and travel counterclockwise around the center island, exiting onto whichever roadway you need.
6. How does a Missouri J-Turn intersection let a driver reach the opposing lanes of a four-lane highway?
Why: A J-Turn intersection avoids crossing fast opposing lanes directly: a driver turns right (same direction as traffic), merges left, then makes a left turn to continue toward their original destination.
