Sometimes the road system in the heavily populated areas is in reasonable condition compared to other developing countries, it can be heavily congested at peak periods
The ceremonial processions also can occupy the whole road but while on the procession, you can also enjoy the colorful experience.
Take note of several important points while driving in Bali . It is not unusual for cars and bikes to swerve into your lane without indication.
A system of "sharing lane" has developed because there are often obstacles on the sides of the road, such as parked cars or the frequent procession of food trolleys and paraphernalia salesman.
It is okay if you are used to it but can be quite shock to the new driver in Bali !
Be aware that drivers from side streets often don't look when joining a main road and the larger vehicle is king of the road.
Quite often, red traffic lights are considered "as suggestion" and there are a few place where traffic in the left lane.
When going around curves on mountainous roads as driver commonly drive in the middle of the road may turn or continue straight through while the light is red remember to sound your horn.
There are a lot of one-way roads in Bali (meant to help traffic flow but it hasn't really turned out the way).
If you miss your turn off, you may have to drive quite a distance before being able to turn back. Be alert! Because this has resulted in motorbike riders riding a few hundred meters in the wrong direction as a shortcut rather than following traffic flow.
You can fill up at any of the many government owned petrol stations or in more remote areas at stalls by the side of the road displaying bottles of clear liquid. The quality may not be as good as at the petrol station.
