driving your rental car in Panama
In Panama you have right-hand-traffic, european traffic rules do mostly apply
The traffic is not very stressful, nobody is in rush - except for Panama-City.
It is not necessary to own an international driver's license to be able to rent a car in Panama. A
European license is enough.
Every person that is crossing the border of Panama with his own car, needs an obligatory car-insurance (to buy at the border). You will also get a special stamp in your passport.
The gas, comparing to other countries in Latin America (Venezuela not included) is very cheap. The gallon (3,785 l) costs around 3 Dollars.
