Cambodia brings revised vehicle-weight and penalty rules into force

The 22 June vote did not make the rules effective immediately

The National Assembly approved the draft unanimously at an extraordinary sitting on 22 June, with all 114 lawmakers present voting in favour. The package revised 15 provisions of the 2014 Road Law: Articles 25, 26, 48–50, 56–61 and 66–69.

At that point, the measure still had to pass through the remaining legislative process. The later legal record changes the status of the story: Royal Kram No. NS/RKM/0726/010 is dated 10 July 2026, and the recorded effective date is also 10 July. Describing the amendments today as merely “approved by parliament” would therefore leave out a material development.

The Ministry of Public Works and Transport said the amendments address maximum vehicle weights on Cambodia’s national road network and update administrative penalties and criminal sanctions for exceeding authorised transport limits. Those subjects are tied to the same 15 articles identified during the parliamentary vote.

The short June announcement does not provide a complete set of numerical thresholds for every heavy-vehicle situation. Operators should therefore avoid treating a single figure quoted in commentary or secondary reporting as a universal limit. The applicable loading rule should be checked against the law now in force and the official enforcement requirements relevant to the vehicle concerned.

For practical context, see Cambodia market and country comparisons. This development also connects with Cambodia Updates Road Weight Rules and Overload Penalties.

Freight planning may need more than a legal-file update

For transport companies and businesses that buy freight services, the practical issue is whether dispatch assumptions, driver instructions and contract pricing still reflect the current legal framework. A payload assumption that was built around the previous rules can affect the number of trips needed, delivery timing and the economics of a route.

Companies using heavy vehicles should therefore review the rules they use to approve loads and make sure operational teams are working from the post-10 July framework. The exact limit and potential sanction depend on the provision that applies to the vehicle and circumstances, so this article is general information rather than a vehicle-specific compliance determination.
