UN R130 Supplement 2 (01 series) · UNECE Regulation No. 130 (ECE R130) — Uniform provisions concerning the approval of motor vehicles with regard to the Lane Departure Warning System (LDWS).
UN R130 — Supplement 2 to the 01 series of amendments
Supplement 1 → 2
- What changed
- New paragraph 1.2. says that the Regulation does not apply to vehicles of Categories X and Y.
- The LDWS function must be deactivated upon activation of an ADS feature and automatically reinstated upon deactivation of an ADS feature.
- The provisions of paragraph 5.3. do not apply while an ADS feature is active.
- Why
- LDWS is a driver assistance feature and therefore has no role while an ADS is performing the Dynamic Driving Task (DDT).
- The warning normally given to the driver that LDWS is switched off is not required while the ADS performs the DDT.
Q1What changed10 changes
Vehicles of Categories X and Y outside the scope (para. 1.2.)
New paragraph 1.2. says that this Regulation does not apply to vehicles of Categories X and Y. Paragraph 1.1. gives the scope: the lane departure warning system of vehicles of categories M2, N2, M3 and N3.
Special provisions for vehicles equipped with an ADS (para. 5.6.)
New paragraph 5.6. gives special provisions for vehicles equipped with an ADS. The LDWS function must be deactivated upon activation of an ADS feature. It must not be able to be activated while an ADS feature is active. The LDWS function must be automatically reinstated upon deactivation of an ADS feature. The provisions of paragraph 5.3. do not apply while an ADS feature is active.
New paragraph at the end of the introduction
A new paragraph at the end of the introduction says that the regulation is amended to account for vehicles equipped with Automated Driving Systems (ADS). It says that LDWS are only required to operate when a driver is in control. It also says that vehicles of Categories X and Y (without the ability to be controlled by a driver) are not required to comply. For vehicles equipped with an ADS other than Categories X and Y, no special provisions or exemptions apply in the manual driving mode.
Footnotes refer to document ECE/TRANS/WP.29/78/Rev.8
Three footnotes now refer to document ECE/TRANS/WP.29/78/Rev.8 of the Consolidated Resolution on the Construction of Vehicles (R.E.3). They also give the new web address https://unece.org/transport/vehicle-regulations/wp29/resolutions. Before, they referred to documents TRANS/WP.29/78/Rev.2, ECE/TRANS/WP.29/78/Rev.2/Amend.3 and ECE/TRANS/WP.29/78/Rev.4.
Q2Why it changed
- Proposed by
- Task force on regulatory fitness for Automated Driving Systems
- Working party
- GRVA, 24th session (January 2026)
Reasons
Lane Departure Warning System (LDWS) is a driver assistance feature. For this reason, it has no role while an ADS is performing the Dynamic Driving Task (DDT).
Source
“Lane Departure Warning System (LDWS) is a driver assistance feature and therefore has no role whilst an ADS is performing the Dynamic Driving Task (DDT).”
Because LDWS has no role while an ADS performs the DDT, the Regulation is not applicable to vehicles of Categories X and Y. The proposal describes these as vehicles with a manual driving capability only below 6 km/h.

“For this reason, this regulation is not applicable for vehicles of Categories X and Y (i.e. with a manual driving capability only below 6 km/h)”
The new provisions are to make sure that the LDWS function is disabled whenever an ADS feature is active. They are also to make sure that it is reinstated when the ADS feature is deactivated. This is when a driver has taken over performance of the DDT. The warning normally given to the driver that LDWS is switched off is not required while the ADS performs the DDT.

“The LDWS function is reinstated when the ADS feature is deactivated (i.e. when a driver has taken over performance of the DDT)”
“The warning normally given to inform the driver that LDWS function has been switched off is not required when the ADS is performing the DDT.”
If one ADS feature is deactivated at the same time as another ADS feature is activated, paragraph 5.6.1. takes precedence. In this case, it is not expected to reinstate LDWS.

“In the case that one ADS feature is deactivated at the same time as another ADS feature is activated (i.e. a transition directly between ADS features), 5.6.1. takes precedent and it is not expected to reinstate LDWS in this case.”
The proposal says that the term “ADS Feature” should be understood to include the Automated Lane Keeping System (ALKS).
