A total of 7,925 drivers were arrested for driving under the influence or reckless driving during the "seven dangerous days of Songkran", says Department of Probation director-general Witthawal Sunthornkachit.
A total of 7,141 were charged with drink-driving, 765 with driving under the influence of illicit drugs and 19 with reckless driving.
Of the 7,141 on drink-driving charges, 13 were also ordered by the court to wear an electronic monitoring device and prohibited from leaving their homes for seven days from 7pm-5am. Ten were in Ubon Ratchathani, and three in Sukhothai.
Mr Witthawal said the number of drivers charged with driving under the influence was up by 1,080 from 6,061 during the same period last year.
All those found guilty of drink-driving would undergo evaluation, and those found to be at risk of becoming addicted to alcohol would be sent to a medical facility run by the Public Health Ministry.
Those considered a repeat-offence risk will be sent for rehab and behavioural adjustment for three days. They will also have to report regularly to probation officials and perform community service, Mr Witthawal said.
