Police say that migrant workers in the southern industrial district around Kaohsiung have become serial road safety offenders, with officers stopping them regularly for offences like drink-driving and riding a motorbike without a license.

There are more than 8,000 migrant workers from Malaysia, Thailand, the Philippines, Vietnam and Indonesia at factories in the county, according to Gangshan Precinct of the Kaohsiung City Police Department, which admits it has problems communicating with them.

Nonetheless, the precinct believes the workers are not making themselves familiar with Taiwan’s road safety regulations, Taiwan Times reported. It cited the case of a 31-year-old Vietnamese man riding a motorcycle with a compatriot on the back who was stopped for suspected drink-driving after the bike was seen speeding by police.

The rider allegedly pretended that he could not understand the police officers when ordered to undertake an alcohol breath test. Police used a Google Translate app, together with body language, to get him to follow their instructions. The man was found to be drink-driving.

Kaohsiung City Police also reminded migrants that it was illegal to ride motorcycles or electric-powered bicycles without the correct government license. Companies were advised to inform and educate their workers about the country’s traffic regulations.
