What action must be taken if a driver encounters a stop sign?

When a driver encounters a stop sign, the correct action is to come to a complete stop and check for other vehicles. This rule is fundamental in ensuring road safety and maintaining traffic order at intersections. The reason it is critical to stop completely is to assess any cross traffic or pedestrians that may be in the intersection or approaching it.

Failing to stop could lead to collisions with other vehicles that have the right of way or could endanger pedestrians attempting to cross the road. Yielding to cars in only the right lane is insufficient; all traffic must be accounted for, regardless of lane position. Additionally, stopping only for pedestrians neglects other vehicles that may pose a risk. The law is designed to promote caution and thoroughness when approaching a stop sign, thereby preventing accidents and enhancing safety for everyone on the road.
