Which system has been mandatory on new cars since April 2018?

The mandatory implementation of an event data recorder in new cars since April 2018 is significant as it serves several important safety and accountability functions. An event data recorder, often referred to as a "black box," captures critical data during vehicle operation, particularly in the moments leading up to and during a crash. This data can include information such as speed, braking status, and seatbelt usage.

The primary benefit of this system is to provide accurate information in the event of an accident, which can be invaluable for accident investigations and liability determinations. It helps improve road safety by informing manufacturers and regulators about vehicle performance and contributing factors in crashes.

In contrast, while advanced braking systems, anti-lock braking systems, and aerial safety systems all play essential roles in improving vehicle safety, they do not bear the legal mandate established for event data recorders in the specified timeframe. The focus on the event data recorder underscores a broader initiative to enhance vehicle safety and enhance accountability in the automotive industry.
