Why people keep dying on Thailand's roads, the most lethal in Southeast Asia

Motorists wait at a traffic light in Bangkok on November 29, 2018.

Bangkok, Thailand (CNN)Driving in Thailand can be a hair-raising experience at the best of times, but during the country's so-called "seven dangerous days" over the New Year holiday motorists take their lives in their hands.

Authorities say the one-week festive period is marred by an increase in crashes, deaths and injuries as Thais travel to visit friends and family.
Efforts to crack down on the causes of those crashes -- drunk driving, corrupt cops and general weak enforcement of traffic laws -- have so far proved ineffective.

The World Health Organization estimated 22,941 people die each year in traffic-related incidents in Thailand, making its roads the deadliest in Southeast Asia.
    That's an average of 62 deaths every day, according to the WHO's 2018 report on global road safety -- just slightly fewer than the average deaths over the New Year period of 66 per day.
    The vast majority of those deaths -- 73% -- are riders of motorcycles, which have exploded in numbers over the past few decades to become the most popular form of transport for most households in the country.

    The northern province of Chiang Mai, which reported the second largest number of incidents this New Year period, with 16 deaths, is a case in point.
