A 20-year-old man allegedly drove against the flow of traffic in Jurong West before hitting a car and a van, with etomidate later detected in his blood.
He is one of two men who are set to be charged in court on Thursday, 3 September, over separate cases of allegedly driving dangerously while under the influence of drugs.
The other man, aged 35, allegedly drove against traffic in Choa Chu Kang in a separate incident.
No one was injured in either case, according to the Singapore Police Force.
20-Year-Old Allegedly Crossed Centre Divider Before Collision
The first incident happened along Jurong West Street 91 at about 8.40pm on 28 October 2025.
Police were alerted to an accident involving two cars and a van.
Investigations found that the 20-year-old driver had initially failed to move when a traffic light turned green.
A bus overtook his car from the right. The man then allegedly overtook the bus from the left and stopped his car.
According to police, he subsequently drove across the centre divider kerb and entered the opposite side of the road.
While travelling against the flow of traffic, his car collided with the right rear of another car and a van.
He then mounted the centre divider kerb again before coming to a stop.
Police said the man appeared unstable and disoriented at the scene.
Officers also found and seized a vaporiser from his car. The vaporiser-related matter was referred to the Health Sciences Authority (HSA).
HSA subsequently detected etomidate in a sample of the man’s blood.
He is set to face charges of driving under the influence of drugs and dangerous driving.
35-Year-Old Allegedly Drove Against Traffic in Choa Chu Kang
The second incident happened about a month later, at around 8.40pm on 26 November 2025.
Police were alerted to a car travelling against the flow of traffic along Choa Chu Kang Way.
Investigations found that the 35-year-old driver had been travelling along Choa Chu Kang Avenue 1 before turning into Choa Chu Kang Way.
He allegedly drove against traffic before turning into a petrol station.
Other motorists had to slow down to avoid hitting his car, police said.
No injuries were reported.
Police said the man appeared disoriented and intoxicated at the scene.
A vaporiser was also seized from his car and the related offence was referred to HSA. Etomidate was subsequently detected in his blood sample.
Like the 20-year-old, he is set to be charged with driving under the influence of drugs and dangerous driving.
What Is Etomidate?
Etomidate has a legitimate medical use as an anaesthetic and is permitted in clinical settings under controlled conditions.
HSA has previously warned that its adverse effects can include involuntary muscle movements, changes in breathing and blood pressure, seizures and psychosis.
The offence of driving under the influence of drugs carries a fine of between S$2,000 and S$10,000, up to 12 months’ jail, or both for a first conviction. Offenders may also be disqualified from driving.
Police said they take a serious view of motorists driving while impaired by drugs or other substances.
