Sleeper buses with 24-40 berths feature narrow aisles, making it difficult for passengers to escape during emergencies like fires, explosions, or rollovers.
Driving through the night under tight schedules, sleeper bus drivers frequently contend with drowsiness and inadequate infrastructure, which together create a high risk of accidents.
Tran Thanh Hai, the sleeper bus driver whose vehicle burst into flames in an accident that killed 7 people, was arrested less than 24 hours after the incident.
A passenger bus was destroyed after hitting a guardrail on national highway 1, with shattered windows, deformed bed frames, and passenger belongings scattered across the grass, on the morning of 21/7.
