The poor road infrastructure, and a mixture of extremely ancient vehicles on the country's roads are all what best describe the road conditions. However, driving habits are not very aggressive compared to say, Vietnam, which does make the safety of the roads comfortable for almost everyone. Although rare, youths often compete against each other on the roads, which has lead to some causalities over the past few years. Bus drivers are among the worst dangers, although this is somewhat less of an issue since 2010 due to new, very harsh penalties imposed on bus drivers involved in accidents.
Surprisingly, Burma has a mixture of both right-hand and left-hand drive vehicles, with the majority being right-hand drive but driving is generally done on the right side of the roads.
Unless you have experience driving in countries with poorly disciplined drivers and very shabby vehicles, avoid driving in Burma.
