If another car has stopped in an adjacent lane in the same direction of travel, you should proceed with caution and be prepared to stop if necessary.
It is important to always be aware of your surroundings while driving and to anticipate potential hazards on the road. If a car has stopped in an adjacent lane, it may indicate that there is an obstacle or hazard ahead, or that the driver of the other car is experiencing car trouble or an emergency.
In this situation, you should reduce your speed, maintain a safe following distance from the other car, and be prepared to stop if necessary. You should also be alert for any signals or hand gestures from the driver of the other car, as they may be trying to communicate a problem or a warning.
It is also important to check your own lane for any potential hazards or obstacles, such as debris or other vehicles, and to always signal your intentions before changing lanes or making a turn. By being cautious and aware, you can help prevent accidents and ensure safe travels on the road.
