A fundamental rule of driving that states you must never drive faster than is safe for the current conditions, regardless of the posted speed limit.
If the posted speed limit is \(65\) mph, but it's raining heavily, how fast should you drive?
You must slow down to a speed that is safe for the wet conditions, which will be below \(65\) mph. This is required by the Basic Speed Law.
What are considered "ideal driving conditions"?
A dry, smoothly paved road during daylight hours with light traffic and good visibility. The posted maximum speed limit assumes these conditions.
What is the primary purpose of speed limits?
To ensure the safety of all road users, including drivers, pedestrians, and cyclists, by establishing a predictable and safe flow of traffic.
Can you be cited for a traffic violation even if you are driving below the posted maximum speed limit?
Yes. Under the Basic Speed Law, an officer can cite you if your speed is deemed unsafe for the current conditions (e.g., fog, ice, heavy traffic).
What does an "absolute" speed limit mean?
An absolute speed limit means that if the posted limit is, for example, \(55\) mph, driving at \(56\) mph is a violation, regardless of conditions. Most speed limits in the U.S. are absolute.
What does a sign saying "SPEED LIMIT 55" mean?
It indicates the maximum legal speed on that stretch of road is \(55\) miles per hour under ideal conditions.
What is the "maximum speed limit"?
The fastest speed you are legally permitted to drive under ideal weather, traffic, and road conditions. It is typically posted on a white rectangular sign.
