Do I Need ETC for Cambodia? 2025 Update
No, you don't need ETC (Electronic Toll Collection) to drive on Cambodia's expressways - but you'll save time and avoid queues with it. Cambodia's first expressway, the Phnom Penh-Sihanoukville route, offers both electronic ETC lanes and manual toll collection (MTC) options.
Key Reality: ETC users with OBU devices enjoy seamless, non-stop travel through dedicated lanes. MTC users can pay via cash, mobile money, or QR codes but must stop at toll booths.
2025 Update: Full toll rates implemented from November 1, 2024, ending the 20% discount period. Two additional expressways (Phnom Penh-Bavet and Phnom Penh-Siem Reap-Poipet) are under development with completion expected by 2027-2030.

What happens if I don't pay Cambodia tolls?
The expressway uses cameras and license plate recognition for enforcement. Unpaid tolls may result in penalties and potential restrictions on future expressway access. Payment is required before exiting the toll plaza.
Do motorcycles pay tolls in Cambodia?
Motorcycles are not permitted on the Phnom Penh-Sihanoukville Expressway. Only cars, buses, and trucks under 40 tons and 5.2m height are allowed.
How do I get an OBU device for Cambodia?
Visit ETC service centers at the expressway entrance, Canadia Bank branches, or other authorized providers. You'll need your passport/ID, vehicle registration, and minimum account balance. Installation and activation are done on-site.
Do tourists get different toll rates?
No, tourists pay the same rates as residents. Foreign visitors can use MTC (manual payment) or set up temporary ETC accounts at service centers with passport identification.
