The Ministry of Transport is seeking feedback on the draft Circular amending Circular No. 31/2019 regulating the speed and safe distance of motor vehicles and specialized vehicles participating in road traffic.
According to the Vietnam Road Administration, Circular No. 31 was issued to provide detailed guidance on the implementation of the 2008 Road Traffic Law. Currently, the 2008 Road Traffic Law has been replaced by the Law on Road Traffic Order and Safety and the Road Law, which came into effect on January 1, 2025.
Therefore, issuing a Circular stipulating the speed and safe distance of motor vehicles and specialized vehicles participating in road traffic is necessary to provide timely guidance on the implementation of the two aforementioned laws.
Accordingly, Chapter 2 of the draft Circular regulating the speed and distance of motor vehicles and specialized vehicles participating in road traffic clearly states: The maximum speed allowed for motor vehicles participating in traffic in densely populated areas (except for expressways and elevated roads without intersections with other roads), motor vehicles except specialized vehicles and motorbikes (including electric motorbikes) traveling on dual carriageways or one-way roads with two or more lanes are allowed to travel at a maximum speed of 60 km/h. Two-way roads and one-way roads with only one lane are only allowed to travel at a maximum speed of 50 km/h.

In addition, the draft Circular also stipulates the maximum speed allowed for motor vehicles participating in traffic outside densely populated areas (except for expressways).
Specifically, for dual carriageways, one-way roads with two or more lanes for motor vehicles:
Passenger cars, vehicles carrying up to 30 people (excluding buses); and trucks with a payload of less than or equal to 3.5 tons are allowed to travel at a maximum speed of 90 km/h.
Passenger vehicles with more than 30 seats (excluding buses); and trucks with a payload exceeding 3.5 tons (excluding tanker trucks) are allowed to travel at a maximum speed of 80 km/h.
Buses; tractor-trailer trucks; motorcycles; and specialized vehicles (except mortar mixers and concrete mixers) are allowed to travel at a maximum speed of 70 km/h.
Trucks towing trailers, trucks towing other vehicles, mortar mixers, concrete mixers, and tanker trucks are allowed to travel at a maximum speed of 60 km/h.
With two-way roads, one-way roads have one lane for motor vehicles:
Passenger cars, vehicles carrying up to 30 people (excluding buses), and trucks with a payload of 3.5 tons or less are allowed to travel at a maximum speed of 80 km/h.
Passenger vehicles with more than 30 seats (excluding buses) and trucks with a payload exceeding 3.5 tons (excluding tanker trucks) are allowed to travel at a maximum speed of 70 km/h.
Buses, tractor-trailers, motorcycles, and specialized vehicles (except mortar mixers and concrete mixers) are allowed to travel at a maximum speed of 60 km/h.
Trucks towing trailers, trucks towing other vehicles, mortar mixers, concrete mixers, and tanker trucks are allowed to travel at a maximum speed of 50 km/h.
Notably, this draft includes regulations on speed limits for electric motorcycles. Specifically, for specialized motorcycles, motorbikes (including electric motorcycles), and similar vehicles, the maximum operating speed is no more than 40 km/h.
