When driving your cheap car rental in Hamilton, keep to the left of the road and pass other cars on the right. You and all passengers must wear their seatbelts all the time and you cannot use a mobile phone without a hands-free device. Drinking and driving is illegal and a blood alcohol level above 0.05% will result in a heavy fine and could mean jail time.
