The USA has a network of sequentially numbered Interstate (I) highways. The roads with numbers ending in 0 cross the country east to west, while those ending in 5 run north to south.

Maximum speed limits are 113kph (70mph) on rural Interstates, 105kph (65mph) on urban Interstates and 88kph (55mph) on other roads. Locals regularly exceed these limits and pass with impunity on both left and right sides. In business or residential districts, a limit of 48kph (30mph) applies. The maximum legal alcohol-to-blood ratio is 0.08%. Both front and backseat passengers must wear seat belts, while children under the age of five years are required to be seated and belted in the back of the car in a child protective seat. Helmets are mandatory for motorcycle riders. As a deterrent, radar detectors are common. Fines can be issued on the spot for seat-belt or helmet offences, speeding and also throwing litter from the vehicle. Drunk-driving is always prosecuted and can result in penalties of up to a US$1,000 fine plus 12 months in jail.
