What action is prohibited when facing a red traffic signal?

When facing a red traffic signal, the action that is prohibited is proceeding straight. A red traffic signal indicates that vehicles must stop and cannot move forward until the light turns green. This rule is in place to ensure the safety of all road users, as red indicates that cross traffic may have a green light and is legally allowed to proceed.

Turning right on a red signal is permitted in Connecticut, provided the driver comes to a complete stop first and checks for other vehicles and pedestrians. Similarly, making a left turn on red is only allowed from a one-way street onto another one-way street, meaning it’s contingent on specific conditions. Making a U-turn is generally not allowed at a red signal since it typically necessitates moving into traffic lanes that may not yet be clear or safe. Understanding these traffic signals is crucial for maintaining safety on the roads.
