What is the recommended maximum speed when making a turn on an Oklahoma roadway?
The answer
Answer: C. Under the Oklahoma Driver Manual, the recommended safe speed when executing a turn is 10 miles per hour or less. Reducing your vehicle's speed before turning gives you full steering control, prevents tire skidding, and allows you to watch for pedestrians crossing the side street.
