Speed limits in Thailand

Like any other countries, drivers who violate the speed limit may be liable to a punishment.

[8] However, due to growing number of automobiles and discrepancies in the implementation, the original law was later amended and superseded in 1969.

As part of the new law, speed limits were set, in 1969, as follows:[5]- 12 years later, it was realised that 100 km/h (62 mph) was too high and not energy efficient.

The government later altered the limit for a small car driving outside the built-up areas to 90 km/h (56 mph), which is still in use today.
