Regulatory, Lane & Parking SignsStandalone practice
You see a white rectangular sign with black letters: SPEED LIMIT 45. The road is dry, and traffic is light. What does the sign tell you?
Correct answer: The sign sets 45 mph as the highest speed allowed on this road.
Why
A white SPEED LIMIT sign states the maximum speed in miles per hour for that part of the road. Oregon describes a speed limit as the highest speed that is safe there in ideal conditions, so rain, fog or heavy traffic can make a lower speed necessary under the basic rule. Some speed limit signs are electronic and change with road, weather and traffic conditions.
