The coastal region around Sihanoukville: the road east toward Kampot through rural Cambodia, the Kampot to Kep drive along the Gulf of Thailand, and the ferry connections to Koh Rong and Koh Rong Sanloem. The road from Sihanoukville toward Kampot — National Road 3 — is about 105 kilometers of mostly good tarmac and passes through Kampong Seila district where documentation points operate on the main road. The Kampot to Kep stretch is Cambodia's most charming coastal drive: 25 kilometers of French colonial road, durian plantations, fishing villages, and the Bokor Mountain silhouette rising behind the coast.

Driving International Association (DIA) is a private independent travel documentation support platform providing International Driving Permit (IDP) assistance and multilingual translation support services. DIA is not affiliated with any government authority, RTO, DMV, or licensing agency. Travelers should verify local regulations independently and always carry a valid domestic driving license.
The junction documentation point at Kampong Trach, on the road between Kampot and the Vietnamese border, sees vehicles checked if you are heading toward Ha Tien in Vietnam. Even if Vietnam is not your destination, the documentation point covers all eastbound traffic on that road. Officers check IDP, home licence, and passport — border proximity means passport is more important here than at inland documentation points.
