Since when have vehicles been required to have turn signals?

The requirement for vehicles to have turn signals began on January 1, 1968. This regulation was implemented to enhance road safety by ensuring that drivers could indicate their intentions to other road users effectively. The use of turn signals helps prevent accidents by making it clear when a driver intends to change direction or lane, thereby improving awareness and communication between vehicles on the road. The introduction of this requirement marked an important step in vehicle safety measures and contributed to more standardized vehicle features across the automotive industry.

While earlier models and various jurisdictions may have utilized signaling devices, it was not until this specific date that it became a mandated feature for all vehicles, ensuring uniformity in road safety practices.
