Road travel in Pennsylvania is excellent, with good state roads connecting Philadelphia, Scranton, Harrisburg and Pittsburgh, as well as outside destinations, such as Niagara Falls and Washington, DC.

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 otherwise.

Driving in the United States is on the right. For UK nationals, a full UK driving licence is sufficient, but some other nationalities may be required to have an International Driving Permit (printed in English and bearing a photograph). Drivers are required to have third party liability insurance, however, collision damage insurance is advised, as costs can be very high in the USA.

The minimum driving age is 16 years. Speed limits are generally 48kph (30mph) in town, 88kph (55mph) on highways and 105kph (65mph) on the interstate highways, unless otherwise posted.

Children under four years of age must be protected in car seats; children age 4 to 8 must use a booster seat.

Pennsylvania has strict drink driving laws and driving while intoxicated is cause for arrest and a criminal charge. The maximum legal alcohol to blood ratio is 0.08%.
