Written comprehension is the ability to understand written sentences and paragraphs. A Traffic Enforcement Agent reads parking regulations, traffic rules, department memoranda, procedural guidelines, and legal documents every day, and accurate reading directly affects the accuracy of every summons and report. On the exam, passages written in this style are followed by questions on the main idea, specific details, word meaning in context, and logical inferences.
Every passage has a central theme or main idea: the primary message the writer wants to communicate. It may be stated in a topic sentence, usually at the beginning or end of a paragraph, or it may be implied by the combined meaning of the supporting details. To find it, ask what single point the whole passage supports. The main idea covers all of the information presented without going beyond what the passage states.
Supporting details provide the evidence, examples, and explanations that develop the main idea. They answer who, what, when, where, why, and how. In traffic enforcement material, details are typically the specific hours when parking is prohibited, exact distances from hydrants or crosswalks, and the vehicle types exempt from a rule. In a parking regulation, the main idea is the general rule; the times, locations, and exceptions are details.

On a detail question, find the sentence in the passage that answers it before you choose. The correct answer must be directly supported by the text. Do not rely on what you know about city rules from outside the passage; if the passage and your knowledge differ, the passage wins.
The exam tests whether you can determine the meaning of a word from the surrounding text. Even an unfamiliar word can be understood from context clues: a definition inside the sentence, an example that illustrates the meaning, a contrast with an opposite idea, or the general sense of the passage. Read the whole sentence and the sentences around it, and look for signal words such as meaning, defined as, such as, however, and in contrast.

An inference is a logical conclusion drawn from stated information. The passage does not say it directly, but what it does say leads reasonably to it. Valid inferences stay close to the text and need only a small logical step. Invalid inferences depend on assumptions, outside knowledge, or speculation.



Reading Procedures and Regulations
Procedural documents set out step-by-step processes. They use numbered steps, conditional language such as if and when, and specific terms. Note words that show sequence (first, then, next, subsequently, finally), conditions that say when an action is required or prohibited, and exceptions that modify the general rule.
Legal and regulatory text is written in precise language designed to minimize ambiguity. Terms are often defined at the start of a document, and those definitions control even when they differ from everyday usage: "vehicle" in a particular regulation may include or exclude bicycles, motorized scooters, or other conveyances depending on how it is defined.

Distractors often change one word in a rule: shall becomes may, all becomes some, before becomes after, or an exception is dropped. Compare each choice to the exact wording of the passage.
