What is a key obligation of drivers regarding speed limits?

Drivers must adhere to posted speed limits at all times because speed limits are established to ensure the safety of all road users. They are determined based on various factors, including traffic patterns, road conditions, and the environment surrounding the road. Following these limits not only minimizes the risk of accidents but also helps maintain an orderly flow of traffic. Speed limits are legally enforceable and are set to protect drivers, passengers, pedestrians, and cyclists alike.

The other options present misunderstandings about the role of speed limits. Suggesting that speed limits are merely suggestions undermines the legal responsibility drivers have to follow the law. The idea that speed can be exceeded if someone is late for an appointment ignores the fact that reckless driving can lead to severe consequences, not only for the driver but also for others on the road. Lastly, claiming that speed limits only apply during the daytime overlooks the fact that they are in effect 24/7, regardless of visibility conditions.
