When passing another vehicle, what is illegal to do?

Exceeding the speed limit when passing another vehicle is illegal and poses significant safety risks. The law requires that all vehicles adhere to posted speed limits to ensure safe interactions on the road. When you pass another vehicle, the goal is to complete the maneuver safely and efficiently, but it should always be done within the speed limit. Driving faster than allowed not only increases the likelihood of losing control but also diminishes the driver's ability to react to any unforeseen circumstances, making it dangerous for everyone on the road.

Changing lanes abruptly can be dangerous, and while using a turn signal is encouraged for indicating your intentions, it is not illegal to signal. Passing on the right is allowed in certain situations but isn't the preferred method of passing, especially if it can lead to confusion or unsafe conditions. However, none of these concerns outweigh the imperative of adhering to speed limits, which is critical for maintaining safety.
