Common Pitfalls for Foreign Drivers

1. Renting a bike without experience

Police will still fine you.

3. Driving in rain

First 5 minutes = ultra slippery.

4. Dogs on roads

Especially Samui & Phangan.

5. Wrong assumptions about overtaking

Thailand = creative overtaking country.

6. Not checking the motorbike brakes/tires

Many rental bikes are poorly maintained.

Driving in Rain – Safety Rules

Rain is the #1 cause of accidents.

• First 3–5 minutes → "oil slick effect"
• Avoid sudden braking
• Keep double distance
• Use headlights always
• Avoid painted lines – extremely slippery
• Watch out for fallen palm leaves & sand patches

Night Driving: Why It's Dangerous

• Poor lighting
• Motorbikes with no lights
• Stray dogs
• Tourists driving drunk
• Potholes invisible at night
• Trucks with dim taillights

Avoid unless necessary – especially on islands.
