A 22-year-old male rider has died after a collision with a truck on an M4 highway off-ramp in  Sydney’s west this morning.

Police say the rider was travelling east on the M4 highway when his motorcycle collided with a truck at the Church Street off ramp about 8.20am (Tuesday 30 July 2019).

“Paramedics arrived at the location and treated the motorcyclist before he was taken by ambulance to Westmead Hospital in a critical condition,” police say.

The rider died soon after.

Our sincere condolences to his family and friends.

Driver tested

The truck was towed for examination and the driver was taken for mandatory blood and urine testing.

There are no details yet on the tests.

However, the Cumberland Police Area Command has established a crime scene and an investigation into the crash has begun.

Police urged the public to exercise extreme care when using the Church Street off-ramp exit due to “heavy traffic conditions”.

After the incident, eastbound traffic on the highway was static for up to 11km.

Anyone with information about this incident is urged to contact Crime Stoppers: 1800 333 000 or https://nsw.crimestoppers.com.au. Information is treated in strict confidence. The public is reminded not to report crime via NSW Police social media pages.

Safety message

It is still not yet known what caused the crash and we do not assume any blame.

Riders should always exercise extreme caution when riding around trucks, especially in heavy traffic.

Trucks have a lot of blind spots and motorcycles can easily disappear from their view.
