Regulatory, Lane & Parking SignsStandalone practice
A white rectangular sign reads SPEED LIMIT 45. What does the number 45 tell you?
Correct answer: The highest legal speed from here until another limit is posted
Why
A posted limit is the most you may drive in good conditions. Montana law also requires a careful and prudent speed for traffic, visibility, weather, and the road, so rain, darkness, or heavy traffic can make a lower speed necessary. A SPEED ZONE AHEAD sign warns you that a lower limit starts soon.
