Road Safety, Family Stops, and Fatigue Management
Road quality improves significantly after entering Thailand; Cambodian sections are potholed but generally passable. Both countries drive on the right side. Speed limits in Thailand are 90 km/h on highways, but during rainy season (June to October), surfaces become slippery, and visibility drops—so reduce speed. Always carry a first-aid kit and emergency contact numbers.
Recommended rest stops include the Phnom Sampov area near Battambang (30 minutes off-route) for its caves and sunset viewpoint, and the Phatthana Nikhom district in Thailand for its roadside fruit markets. For families, the Battambang bamboo train and the Chainat Bird Park are engaging stops. Pets are allowed in most hotels, but always confirm in advance.
- Rest every 2-3 hours or every 200 km.
- Use the rest zones at Sangkae (Cambodia) and Sikhio (Thailand).
- Hydrate consistently; avoid driving during peak afternoon heat (12-3 PM).
For food, both countries offer roadside noodle shops and coffee stalls—consider local favorites like Cambodian kuy teav and Thai boat noodles.
