UN R28 Supplement 6 (00 series) · UNECE Regulation No. 28 (ECE R28) — Uniform provisions concerning the approval of audible warning devices and of motor vehicles with regard to their audible warning signals.
UN R28 — Supplement 6 to the 00 series of amendments
Supplement 5 → 6
- What changed
- New paragraph 2.4.5. defines “Electronic” as a principle of operation by electric or electro-magnetic force with amplifier and speaker or resonator.
- Why
- The proposal aims to take into account new technologies that can emit an acoustic signal. The signal is intended to give audible warning of the presence of a vehicle in a dangerous road traffic situation.
- The proposal names especially piezo-electric devices, such as a loudspeaker that could emit an acoustic signal.
- The proposal states that the approval test remains the same, because the testing procedure is performed with the current supplies.
Q1What changed1 change
New “Electronic” principle of operation (para. 2.4.5.)
New paragraph 2.4.5. defines “Electronic” as a principle of operation by electric or electro-magnetic force with amplifier and speaker or resonator.
Q2Why it changed
- Proposed by
- Experts from France
- Working party
- GRBP, 70th session (September 2019)
Reasons
The proposal aims to take into account new technologies that can emit an acoustic signal. The signal is intended to give audible warning of the presence of a vehicle in a dangerous road traffic situation. The driver intentionally operates the signal.

“to take into account new technologies that permit to emit an acoustic signal which is intended to give audible warning of the presence of a vehicle in a dangerous road traffic situation and which is intentionally operated by the driver.”
The proposal names especially piezo-electric devices, such as a loudspeaker that could emit an acoustic signal.
Source
“It is the case especially for piezo-electric devices, such as a loudspeaker that could emit an acoustic signal.”
The proposal states that the approval test remains the same, because the testing procedure is performed with the current supplies.

“As the testing procedure is performed with the current supplies, the approval test remains the same.”
For quiet road transport vehicles, the same device could be used for both audible warning signals and the Acoustic Vehicle Alerting System (AVAS).
