Just the facts.

Approximately 2 p.m. today on Motorway to Pattaya there is a big bus accident approx 3 km east of the Bang Pa In turnoff. Probably a 1-2 hour delay travelling easbound so if you are heading to the airport leave plenty of time (or take the airport express or go via Bang Na). When I passed it was a 3 km traffic backup (travelling east) and about 1 km travelling west (towards Bangkok)

And the driver fled the scene...
