Define "traffic stop" and its legal implications.

A "traffic stop" is defined as a lawful detention by law enforcement officers for the purpose of investigating suspected traffic law violations. This definition is central to understanding the legal framework surrounding traffic enforcement. When an officer initiates a traffic stop, it is based on reasonable suspicion that a violation has occurred, such as speeding, running a red light, or driving under the influence. The officer has the authority to temporarily detain the driver to ensure compliance with traffic laws, and during this time, they may inquire about the driver's license, registration, and insurance.

The legal implications of a traffic stop hinge on the necessity for probable cause or reasonable suspicion. These stops must adhere to constitutional protections against unreasonable searches and seizures as outlined in the Fourth Amendment.

Additionally, limiting traffic stops only to nighttime ignores the fact that such stops can legitimately
