A tailgate is the rear door or panel of a vehicle, typically on a truck or SUV, that can be opened to allow access to the cargo area. It is hinged at the bottom and can be lowered or swung open to make it easier to load and unload items. Some tailgates are also designed to support extra functions, such as serving as a workbench or providing additional storage space.

Traffic refers to the movement of vehicles and people along roads or streets. It involves cars, buses, bicycles, and pedestrians moving from one place to another. The flow of traffic can vary depending on the time of day, road conditions, and the number of vehicles or people. In busy areas, traffic can become slow, causing delays. Proper management of traffic helps ensure safety and smooth movement on roads.

A red light in traffic is a signal that tells vehicles and pedestrians to stop. It is part of a traffic light system that controls movement to keep roads safe and organized. The red light appears after the yellow light and remains on for a set time before changing to green. Drivers must wait until the light turns green before moving forward or turning, unless a separate signal allows a turn. Traffic lights help prevent accidents and manage the flow of movement at intersections and crossings.
