What must a driver do at a red signal light in Pennsylvania?

In Pennsylvania, when a driver encounters a red traffic signal light, the law requires them to come to a complete stop at the intersection. After stopping, the driver may then proceed to turn right at the red light unless there are signs indicating that such a turn is prohibited. This rule is in place to enhance road safety and ensure that vehicles do not move through intersections recklessly.

The permissibility of turning right on red, after stopping, is a commonly practiced traffic regulation in many states, including Pennsylvania. This option allows for a more efficient flow of traffic, provided that the driver yields to any oncoming vehicles or pedestrians who have the right of way.

Other responses do not accurately reflect the law regarding traffic signals. Proceeding without stopping would violate the requirement to halt at a red light and could lead to dangerous situations. Turning left at a red light is generally not allowed unless the driver is on a one-way street and turning onto another one-way street, which is not specified in this context. Yielding to oncoming traffic, while important in various driving situations, does not apply directly to the actions required at a red signal light when a proper stop is the foremost action mandated by law.
