●Have you ever heard a “ding-dong sound” while driving?
●Why did the ding-dong sound (speed warning sound) disappear?
●The second-generation Civic is the last car model with this feature as standard...
●I feel a little nostalgic when I think of the "ding dong sound"
Drivers over 60 years old may have heard the ding-dong sound from vehicles when they were young, while those aged 30 to 40 years old may have heard the ding-dong sound in their parents' car when they were young.
The ding-dong sound you hear when driving on the highway is officially called the "speed warning sound." Generally, when the speed of a car exceeds 105km/h and the speed of a light vehicle exceeds 85km/h, a ding-dong sound will continue to sound.
This is because Japan's "Partial Amendment to the Safety Standards for Road Transport Vehicles, etc." in 1974 stipulates that this equipment is mandatory, so all vehicles manufactured at that time were equipped with speed warning sounds.
At that time, it was considered very dangerous to drive at a speed exceeding the speed warning sound, so safety standards made this equipment compulsory. Considering the car design (high-speed cruising performance) and road conditions at the time, it is understandable that this safety equipment is necessary.
But recently I haven't heard the ding-dong sound from the vehicle. When did this sound start to disappear?
As mentioned above, the compulsory speed warning sound is a standard established in Japan. On the other hand, this requirement does not exist abroad, and only Japanese cars are equipped with speed warning sounds. This also became a huge barrier to the import and export of vehicles at that time.
To foreigners, Japanese cars "are cars that make loud noises." Due to the mandatory installation in Japan, when importing overseas vehicles, vehicle inspection and other certification operations are very time-consuming, which is regarded as a major problem.
After listening to this opinion, the Japanese government removed the obligation to install speed warning sounds from the security standards in March 1986. It is very rare for a technology that was once included in security standards to be removed like this.
One of the reasons for deletion is that "the monotonous warning sound may induce drowsiness," but it is honestly difficult to believe that this reason was the main reason behind the decision to delete it. The speed warning sound is obviously a barrier to Japan-US trade, and this barrier has also been dismantled by the push from overseas.
After the compulsory regulations were abolished in 1986, vehicles in circulation in Japan were still equipped with speed warning sounds, but they gradually disappeared. Among commercially available models, only the second-generation Honda Civic remains with it as standard equipment.
The speed warning sound remained until the early 2000s, and some models still made it a dealer option. But after 2010, it was removed from dealer options and its existence completely disappeared.
Even if the speed of light-duty vehicles currently on sale exceeds 85km/h and the speed of ordinary cars exceeds 105km/h, there will no longer be a ding-dong sound. And now the maximum speed limit in some sections of the highway has reached 120km/h, which greatly exceeds the set value of the speed warning sound. Vehicle performance and road conditions have changed dramatically compared to 1974.
The author heard this sound in a 1989 Toyota Camry. I was a child at the time. I was driving on the highway and half asleep when I heard the "ding dong, ding dong" sound.
The father who was driving at the time was afraid that the sound would wake his family, so he slowed down to a speed where the warning sound would not sound.
It is now regarded as a non-essential equipment, but for the author as a child, it was a moment when I felt my father's care for his family while driving. In addition to urging drivers to pay attention, it is also an opportunity for drivers to regain their awareness of "driving home safely".
It is a very nostalgic sound for those who drove while listening to the ding-dong sound at that time, and for the passengers in the passenger seat and back seat.
The author thinks that this function does not need to be completely resurrected, and it does not matter. If it can be equipped with an ON/OFF switch, it will be very happy to be installed as an equipment on modern cars.
