Speed limits are the maximum legal speed under ideal conditions. The basic speed law requires drivers to slow below posted limits when conditions such as rain, fog, traffic, or visibility require. Posted limits do not give permission to drive recklessly.
What the exam tests
Speed Limits is one of the topic areas every state DMV exam pulls from. Expect roughly two to five questions per exam from this category, depending on your state. The questions test both your recognition of the underlying rule and your ability to apply it to a specific scenario such as a four way stop, a yellow advisory speed sign, a school bus with extended stop arm, or an emergency vehicle approaching from behind.
Core rules to remember
Posted maximums and the basic speed law. The exam will phrase the question with a concrete scenario, then offer four answers that include the correct rule, a plausible distractor, an incorrect generalization, and a clearly wrong option. Read every choice before answering. Eliminate the obviously wrong options first, then choose the most precisely correct of the two that remain.

Why this topic matters
Speed Limits questions are not the kind of trivia you can guess your way through. Get this topic wrong on the road and you risk a crash. Get it wrong on the exam and you delay your permit by at least a day, often a week. The rules in this category are written for the situations that historically cause the most fatalities, so the exam takes them seriously and so should you.
