Cuba is about 1100 km from one end
to the other. Driving can be hard especially in a car without
air-conditioning. The roads (with few exceptions) are bad and the further
east you go the worse they get. Potholes, lack of street lights, ...
even disappearing roads combined with inadequate signalization make it
unadvisable to drive at night. Also watch it within the cities a holes dug
for roadwork are not or badly signalled.
The rules are very simple:
avoid driving at night
take plenty of water along
(bottles sold in every gas station)
fill your tank on time
adapt your speed to
conditions
make sure you have a good
road map
take time to rest
