Here is the most critical insider knowledge for first-time drivers in Asia. At first, the traffic can feel like pure hell. Your first thought might be panic; your second must be acceptance.
Vietnamese motorcyclists rule the road. They occupy all available space, and their driving style is intuitive, organic motion that doesn't always adhere to the traffic laws we know. They operate on the assumption: "I am going, you see me."
- The Honk Phenomenon: They honk constantly. This is not aggression; it is the sonic language of the road, a way to announce their presence. A Vietnamese driver honks to say: "I'm passing on the right," "I'm pulling out of this alley," or simply, "I'm here." Your reaction must be calm and steady. Don't swerve or brake sharply; maintain your trajectory and be predictable.
- Navigating the Swarm: How does a car survive this endless flow of motorbikes?
- Be Big, But Gentle: In the eyes of motorcyclists, you are a large, predictable, slow-moving object. Use your size to gently slice your way through the flow.
- Pedestrian Pace: Drive slowly but smoothly. Your speed should be just above walking pace in dense areas. This allows you to see them and allows them to flow around you easily.
- Intentions Over Reflexes: Constantly check your mirrors, but focus primarily on clearly signalling your intentions (turning, braking). Merge into the current; do not fight it.
- Documentation Insight: An experienced traveller knows a local license is not enough. You must carry an International Driving Permit (IDP) issued under the 1968 Vienna Convention. As I did, you can often obtain a translated local document on their language by visiting the local traffic authority (GAI/DMT) with a translator. My documents were ready in two days!
