In Texas, what does a solid red traffic light mean?

A solid red traffic light in Texas means that drivers must come to a complete stop at the intersection. This signal indicates that cross traffic has the right of way and that vehicles must not proceed until the light changes. The purpose of the red light is to ensure the safety of all road users by controlling the flow of traffic and preventing collisions. When faced with a solid red light, drivers should look for any signs indicating whether a right turn on red is permitted after stopping and yielding to pedestrians and other vehicles.

Other options, such as proceeding with caution or slowing down, are not appropriate responses to a solid red light as they do not comply with the traffic control intended to maintain safety at intersections. Pedestrian crossing signals operate separately and are governed by other lights that indicate when pedestrians can safely cross, making them irrelevant to the meaning of a solid red traffic light.
