The first two days of the "seven dangerous days" of New Year travel have resulted in 20% fewer road deaths than in the same period a year ago, officials said on Saturday.
Statistics for Friday showed 576 road accidents, 49 deaths and 609 injuries, up from the day before but down from the corresponding day a year earlier.
The cumulative death toll of 90 for the first two days is 23 less than in the same period a year ago, officials said.
Drink-driving caused 42% of the accidents reported on Friday and speeding 23%, according to Karoon Sakulpradit, permanent secretary for the Education Ministry, who provided the update on Saturday.
Motorcycles were involved in 78% of the accidents and the most common time for accidents was between 4pm and 8pm.
Officials at checkpoints cited 33,630 people for failing to wear crash helmets and 32,936 for having no driving licences, said Mr Karoon.
The highest number of accidents on Friday, at 25, was reported in the southern province of Nakhon Si Thammarat. Three provinces -- Pathum Thani, Phitsanulok and Ubon Ratchathani -- recorded three deaths each. The highest number of injured people (29) was also in Nakhon Si Thammarat.

Nakhon Si Thammarat had the highest two-day total for accidents (44) and injuries (48), while Si Sa Ket had the most deaths at seven.
