Road

Text : The general rule for numbering on US freeways and interstates is that the odd numbers go north?south and the even numbers go east-west over their whole length, although at any single, localised point this may seem different. Driving in America is on the right and the speed limit is 48kph (30mph) in the city unless otherwise posted, 80kph (50mph) outside the city limits and 105kph (65mph) on freeways. Speed limits are clearly indicated along highways and are strictly enforced, with heavy fines imposed. Driving visitors should note that it is illegal to pass a school bus with flashing red lights. It has stopped to unload its passengers and all vehicles must stop until the bus has moved back into the traffic stream. Right turn on red is not permitted in New York City. Seatbelts must be worn (both front and rear) and drivers must carry their driving licence. Drink-driving laws are very strict and punishments severe. A blood alcohol level of 0.08% is illegal and drivers will be considered drunk and unable to drive.

The minimum driving age is 16 years. An International Driving Permit is recommended, although it is not legally required and a full national driving licence is accepted. All travellers intending to drive in the USA are strongly advised to acquire supplementary insurance. A yellow 'non-resident, interstate liability insurance card', which acts as evidence of financial responsibility, is available through motor insurance agents.
