They have suggested the checks should resume on December 31.
Since July 1 police have been pulling up trucks and penalising those running without the requisite licences.
The transport ministry said only 10,467 out of 19,828 vehicles nationwide have licences.
As a result of the checks, many lorries in busy port cities like Ho Chi Minh City, Da Nang, and Hai Phong have chosen to stop plying, leaving containers accumulating at ports.
In Ho Chi Minh City, the number is nearly 40 per cent and in Hai Phong it is 30 per cent, according to local transport associations.
Following investigations, the transport ministry has concluded that the delay in obtaining licences was not caused by training, testing, or issuing centres but by the reluctance of businesses and drivers to spend time to obtain them.
