What should the driver do after stopping at a stop sign?

After stopping at a stop sign, the driver should look both ways and then proceed. This action is crucial for ensuring the driver's safety as well as the safety of others on the road. Stopping at the stop sign indicates that the driver has acknowledged their obligation to yield to any oncoming traffic or pedestrians before continuing.

By looking both ways, the driver is confirming that the intersection is clear of vehicles and pedestrians. This practice helps to prevent accidents, as it's important to ensure that there are no vehicles approaching from either direction, especially those that may not be stopping. The requirement to stop and look reinforces defensive driving techniques, promoting awareness of surrounding traffic conditions.

Other choices do not encompass this essential safety measure. For instance, proceeding immediately ignores the need for vigilance, while waiting for five seconds adds unnecessary delay without a safety benefit. Turning on hazard lights does not pertain to the action required after a stop sign and can confuse other drivers regarding the vehicle's intentions. Thus, looking both ways before proceeding is the safest and most responsible choice a driver can make at a stop sign.
