A 40-year-old motorcyclist was pronounced dead at the scene after a three-vehicle crash on the Ayer Rajah Expressway toward Tuas on Saturday afternoon, Singapore police said. The collision blocked two lanes approaching the tunnel entrance near Tuas West Road and forced travellers heading to Malaysia to queue for much of the evening.
Timeline and road closures
Police said they were alerted at about 3:35 p.m. Officers and Singapore Civil Defence Force paramedics reached the westbound carriageway between Tuas West Road and the checkpoint approach. Despite treatment on site, the rider could not be revived.
The Land Transport Authority posted on X shortly before 3:10 p.m. that an accident had occurred after Tuas West Road and asked motorists to avoid lanes one and two. Expressway Monitoring and Advisory System cameras showed two of three lanes barricaded while investigators documented skid marks and vehicle positions.
Checkpoint knock-on effects
The Immigrations and Checkpoints Authority warned at about 3:40 p.m. that drivers using Tuas Checkpoint should expect delays because the crash sat at the mouth of the tunnel feeding the border complex. ICA advised travellers to divert via Tuas West Road rather than staying on the blocked expressway lanes.
Weekend cross-border traffic often peaks in the late afternoon as Malaysian workers and shoppers return. Saturday's backlog extended onto connector roads even though the accident was several hundred meters short of the immigration booths. ICA cleared all lanes by about 8:15 p.m. after wreckers removed the vehicles.
Investigation and safety context
Police said inquiries are ongoing and did not immediately identify the cars involved or whether passengers were injured. No arrests were announced Saturday evening.
The crash is at least the third fatal traffic incident reported in Singapore within a week involving motorcyclists or cyclists, according to local media tallies. Traffic Police statistics released earlier in 2026 showed overall accident counts rising even as fatalities fell, largely because fewer motorcyclist deaths were recorded in the first half of the year.
What travellers should expect
Drivers bound for Tuas Checkpoint on weekend evenings should continue to monitor LTA and ICA social channels; secondary accidents often form when queues spill back onto the AYE. Riders remain over-represented in severe injury cases on expressways where speed differentials between cars and motorcycles are widest.
Police asked anyone with dashboard footage or witness accounts to submit information through the Singapore Police Force portal. The force did not release the victim's name pending next-of-kin notification.
