Final answer:
The correct way to change lanes in heavy traffic is to use your turn signal and check your mirrors. It's important not to speed up abruptly, cut off other drivers, or ignore other drivers, as these actions are dangerous and can lead to accidents.
Step-by-step explanation:
When you intend to change lanes in heavy, rush-hour, city traffic, the safest and most appropriate action is to use your turn signal and check your mirrors before making the lane change. This is the correct method to indicate your intentions to other drivers and ensure you are aware of the traffic around you.
Speeding up to quickly move into the next lane can be dangerous and is likely to cause an accident or at the very least, startle other drivers. Cutting off other drivers to get into the desired lane or ignoring other drivers and changing lanes abruptly are also unsafe practices that can lead to traffic accidents and are considered aggressive driving behaviors. Being calm, patient, and respectful of traffic laws and other motorists is essential for the safety of everyone on the road.
