At a stop sign, if a car approaches from the left signaling a right turn, is it safe to assume they will make the turn?

In situations involving stop signs and other traffic controls, it's essential to be cautious and not make assumptions about other drivers' intentions. Just because a vehicle is signaling a turn does not guarantee that the driver will complete that maneuver. The driver may change their mind, may not see you, or may even misjudge the timing of their turn in relation to your approach.

In this context, it’s critical to approach the intersection prepared for various possibilities. The vehicle may come to a complete stop before making the turn, they might decide not to turn at all, or they might turn without adequately checking for other vehicles. These factors emphasize the importance of maintaining a defensive driving attitude – always assume that other drivers may not act as expected.

Drivers should be prepared to yield the right of way or stop if necessary, regardless of the indications from other vehicles. This approach increases safety for all road users, making it prudent to not assume the action of a driver at an intersection.
