Driving around Sihanoukville is a full on experience. here are some rules:
1. If his car is bigger than yours, Move !
2. Don't trust red lights cambodians don't
3. Always wear a helmet
4. If stopped by police remember: they only want your cash
5. Never hesitate, you might die doing so.
6. Drink driving is legal in cambodia but it is illegal to have your headlights on during the day (Logical ???)
7. Don't try and be a Khmer driver (More than 5 people on a moped is a feat for any westerner)
