Effective November 1st: Traffic signs prohibiting turns and U-turns will be changed.

From November 1st, Circular 06/2016/TT-BGTVT, issued on April 8th, 2016, on the National Technical Standard for Road Traffic Signs, will come into effect. Notably, there are changes to the regulations regarding some traffic signs.

Accordingly, the regulations on signs prohibiting left turns and right turns, as stipulated in Circular 06/2016/TT-BGTVT, are as follows:

"To indicate a prohibition against turning left or right (in the direction of the arrow) at intersections, sign P.123a "No Left Turn" or sign P.123b "No Right Turn" must be placed."The sign does not prohibit U-turns.".

Circular 72/2012/TT-BGTVT (replaced by Circular 06 and will cease to be in effect from November 1st) stipulates that if a "no left turn" sign is posted, vehicles are also not allowed to make U-turns.

According to the old regulations, vehicles were not allowed to make U-turns if they saw these two signs.

Therefore, according to the new regulations in Circular 06, from November 1st, signs prohibiting left and right turns will no longer include signs prohibiting U-turns.

Regarding the prohibition of U-turns, Circular 06/2016/TT-BGTVT has added new traffic signs with the following specific regulations: "No left turn and no U-turn", "No right turn and no U-turn", "No left turn and no U-turn for automobiles", and "No right turn and no U-turn for automobiles".

Traffic sign P.124a prohibits all types of vehicles (motorized and non-motorized), and traffic sign P.124b prohibits cars and three-wheeled motorcycles (sidecars) from making U-turns, except for priority vehicles as stipulated.

Accordingly, to indicate a prohibition against U-turns, sign P.124a "No U-turns" must be placed. The arrow direction should correspond to the direction in which U-turns are prohibited.

To indicate a ban on U-turns for automobiles, sign P.124b "No U-turns allowed for automobiles" must be placed. The arrow direction should correspond to the direction in which U-turns are prohibited.

To indicate a ban on both left turns and U-turns, sign P.124c "No left turn and no U-turn" must be placed.

To indicate a ban on all types of vehicles turning right and making U-turns, sign P.124d "No right turn and no U-turn" must be placed.

To indicate a ban on left turns and U-turns for automobiles, sign P.124e "No left turns or U-turns for automobiles" must be placed.

To indicate a ban on right turns and U-turns for automobiles, sign P.124f "No left turns or U-turns for automobiles" must be placed.

Traffic sign P.124a prohibits all types of vehicles (motorized and non-motorized), and traffic sign P.124b prohibits cars and three-wheeled motorcycles (sidecars) from making U-turns, except for priority vehicles as stipulated.The sign does not prohibit turning left to go in a different direction.

If a "No U-turn" sign or a "No U-turn for automobiles" sign is placed on a road section that is not an intersection, the starting point of the prohibition must be indicated by sign S.503d "Direction of effect of the sign" placed below the main sign.

Before or after locations where no U-turn signs are posted, signs indicating U-turn locations (sign number I.409 or I.410) must be placed.
