+ 13meters for grade-III roads;

+ 09 meters for grade-IV and grade-V roads;

+ 04 meters for under grade-V roads;

- For urban roads, limitation of road safety corridor shall be the red boundaries under the planning approved by competent authorities.

- For expressways outside urban areas:

+ 17 meters, measured from land area of road to both sides;

+ 20 meters, measured from the outer edge of outermost structure to each side for dry bridges and trenches;

+ In case expressway with road at its side, based on technical level of road at its side to determine the safety corridor according to Clause 1 of Article 15 of Decree 11/2010/ND-CP (amended in Decree 100/2013/ND-CP) but not less than the limitation of safety corridors defined in point a, point b Clause 1 of Article 15 of Decree 11/2010/ND-CP (amended in Decree 100/2013/ND-CP).

In case a road and a railway are adjacent and share a longitudinal trench, the boundary between their safety corridors is the bottom edge of the trench on the higher roadside. If the heights of the two corridors are equal, the boundary between the safety corridors is the bottom edge of the trench on the railway side.

- For roads with safety corridors overlapping protection corridors of inland waterways, the boundary of these corridors is the edge of the natural bank.
