UN R79: Proposal for a Supplement to the 03 series of amendments
Reference Number: GRVA/2020/7
Proposal to increase maximum lateral acceleration limit values up to 4m/s² for speeds up to 80 km/h for M1/[N1] category vehicles, provided there is no heavy rain and ambient air temperatures are above 4°C.
Proposal to allow ACSF-B lateral acceleration above the maximum limit value in cases where the lane position cannot be maintained by the vehicle (for example, on a tightening curve).
