What should you do at a stop sign?

At a stop sign, the correct action is to come to a complete stop and yield to other vehicles. This is critical for ensuring the safety of all road users. The stop sign indicates that you must halt your vehicle completely before proceeding, allowing you to check for any oncoming traffic or pedestrians. This practice helps prevent accidents by ensuring that you are completely aware of your surroundings before you make any movements.

Other options suggest incomplete adherence to the stop sign rules. For instance, merely slowing down and proceeding if there are no cars present can lead to dangerous situations if another vehicle unexpectedly approaches. The option about stopping only if there are oncoming vehicles does not account for cross traffic or pedestrians that may also have the right of way. Lastly, waiting for a flashing green light is not relevant at a stop sign; stop signs dictate a full stop regardless of traffic signals and are crucial for safe driving practices.
